You should never replace computerized electrical components without first disconnecting the battery. That and the unit is grounded by the mounting bolts (which were not installed upon start-up) so that too could potentially damage the unit. Other than that, God bless you, Charles!
Humans helping humans. So marvelous!
I had a "no crank, no start" condition on my 2003 Town and Country - 216,000 miles - babied it's entire life. I had two "hiccups" in the month preceding the ECM/PCM totally failing where I had very brief "no crank, no start" moments but they were so split second, I second guessed if I was actuating the keyed cylinder completely. Once I was "into" the condition fully, I started to troubleshoot fuses, relays, starter, battery, ignition switch and surmised that the ECM was the culprit. I ordered a replacement from All Computer Resources in Homestead, Florida (couldn't recommend them more strongly - they were awesome) and it fixed me up. Back on the road, van running as good as ever.
THANK YOU, Charles!!! May blessings come to you 7-fold!!!❤️And YEAH, Denoy!!! SO HAPPY that now you, and your precious family are SAFE & mobile again!!! 😊
Thank you Charles! I'm sure God will bless you for that! What blessing to see Denoy helped! Denoy, a lot of us pray for you!
How can I get a hold of Charles I need him to do me a computer and I can buy it off of him or whatever and I have a 2003
Charles, you little beauty. What a great guy you are to help Denoy in this way. You are a hero!!!!
way to be a friend Charles
Thank you Charles. Thank you God.
Little Blue Two,
We Love You.
Charles ROCK!! U owe that man big time.....free service at that also wow.
Thank you CharlesThank you God Little BlueTwo,We Love You.
Awesome job Charles. Hello Denoy the problem to the A/C blower only working on high might be a defective HVAC blower motor resister. They usually default to work on high only when they go bad. If you have a friend that has A/C gauges he might help you if you need freon or tell you if it is completely empty of freon. God bless you Danoy keep on vaning
I’m Just looking at ur video now and reading same time.. I’m not sure if fig out blower motor issue.. I have a 2001 DGC and my blows every time in summer time .. idk if they are ongoing issues or when the dealer I bought it off from it was Nissan dealer put in cdc player..
It’s inside the glovebox I replaced mine like 4xs each year.. it seems to blow at lower levels then high.. I hope u got ur fixed…
Comment about compressor now mine was under a recall it was replaced.. idk if ur your included
thanks Charles!... subscribers can really blow your mind
Awesome! great to see Lil's blue running well. hopefully you'll solve the AC problem as well.
Truly plug and play, awesome! Tx for the great video!
Pick up a 3M headlight lens cleaning kit for $10 on Amazon so you can see at night...will make those yellowed lenses new again. Also, a new blower motor control/resistor will allow all fans speeds. Cheap and ez to replace, about $8 Rock Auto. God bless.
Can also try wd40
Next time, disconnect the battery first, when you plug in the new unit.
ggin nj Thanks. Hopefully, others who may need to do this are reading this.
@@LivingInAVan I would put that in your description at least in bold letters.
@Jesse 4R My car won't start, but every other part related to the ignition is good. Battery, fuel pump, starter, and alternator. I have code p0401, I failed the smog test. I'm about to replace the EGR valve and the vacuum hose. What are your thoughts on this?
Yea agree bcz DGC are very touchy.. I just wished my family listen to me I told them that.. I would put that in description on all ur work
Well I need Charles's help my 2003 is broke down and somebody said I need a computer how can I get one without it costing $700 at the dealership plus however much it is for them to put it in there's only three bolts
Check the resister blower motor in the glove box to repairr your ac problem, you must drop the glove box down and the motor is there
Like wise lol
I don't know why Chrysler did this but the check engine light in 2002 was on the stupid piece of plastic on top of the dash. In 2003 they moved the check engine light to the gauge cluster and then they replaced the oil pressure light and check engine light that was on the piece of plastic on top of the dash with warning lights for diesel vehicles a glow plug warning light and a water in fuel light and I'm guessing they moved the oil pressure light to the gauge cluster too
LIL BLUE LIVES
Good video! Charles saved your but and you saved ours. Good pay it forward video.
that is so awesome! I can stop worrying about you getting stranded in the middle of nowhere! And it gives me just a tiny bit of hope that just maybe I can find a Prius before I have to be out of this house!I would be happy with any vehicle but as you know a Prius would be the best option.cross your fingers!I wonder how much farther lil blue II will go,maybe you can make that million now! lol
charle do you r my hero.....🎉🎉🎉
Thank you Charles
simms196 God bless you charles
Good luck.
The fan only working on high is the resistor pack. About 30.00 or 40.00
ggin nj knows the right answer!!! its definitely the problem...... if the fan only works on high its the Blower Motor Resistor for sure
Really mine only cost me less 20$ with lifetime…
👍🏻 Charles
You're awesome Charles!
If you didn't change your injector harness... You'll be replacing that pcm soon. The injector harness is that causes 99% of the issues with the pcm in these vans
What is the link between the injector harness and the PCM ? My injector in the center front of the motor don't work. I mesure 13 volts on one of the wire of the connector and 0.3 volt on the other wire. So, I suspect it is the PCM/EMC that fail to apply the ground to the injector. Can I change the ECM for a 2007 version instead of 2005? And if I change the ECM, will I be able to start the car or does it have to be reproprammed at the concessionary first? And what is the link with the injector harness?
@@alainlangdon it melts and short circuits when the wire coating comes off. Then it burns out the coil drivers in the pcm, making the pcm trash
@@goclunker Thank you for the information. For the other problem I mentionned in my question, I just disconnected the battery for an hour or so. It resetted the ECM and now it seems that the injector works. Because the ECM detected something was wrong with that cylinder, it shotdown that injector even though I had change the injector and the harness. The trick was to reset the ECM.
@@alainlangdon not quite. This car doesn’t shut down individual injectors. They can overheat and stop working, from experience. Usually caused by: clogged cat, melted harness and or broken tps. Any combo of these.
@@goclunker You are right, the problem came back today. My injector number 4 in the front center is still not working again. I tried the battery reset again but it did not worked this time. I'm not sure what is going on. Maybe reprogram the ECM/ECU ? Maybe change it ? If only I knew which wire to test on the PCM/ECU...
yeah little blue two. yeah Charles.
I'm about to do this on my 2002 blue Grand Caravan SE. My problem was the 5th cylinder was misfiring while driving. A repair shop replaced the harmess but could not fix the issue. I brought up the computer and they kinda dismissed it.
Me working with computers as my job-I know even something like a PCM could get hosed up.
The power steering reservoir leaks on the assembly and causes problems. I think that's what was wrong on mine and not the pcm...so double check the ignoring coil, sparkplug, cable, etc.
For those who are watching this my 2002 grand caravan had similar fan speed issues the blower motor needed replaced cause it burned up due to me being to change the blower motor resister and it allows all speeds to work it's under the glove box take it out it's the one with all the wires going into it, for your information also the blower motor is a pain in the ass to change do to a bolt in the back that requires a flexible ratchet avoid that
Yea that’s what I’m worried about bcz I’ve replaced the resistor so many times and one winter my blowe motor was catching and u could smell it.. it is a pain had a friend of friend that help me and clean it and greases it and working but Ik it heading to go out again..
@@theresam8809 the bolt for the blower that is hard to get out, just keep it out when you get it, there's no reason to put it back the others are important for making the cover solid that one is ridiculous, and be careful, I'm a bigger guy I got stuck in my glove box, but don't worry I think you'll get it... Just go under there you'll figure it out friend
@@erichart2756 oh ok, thank u for ur reply and help.. sorry to hear u got stuck lol. Not fun.. I appreciate it… thanks!
The AC issues might be from a bad resistor. Especially if Its not blowing on all settings
I was working under the hood once with a nice gold 3 diamond ring on. It shorted out between a positive and ground, getting super hot melting a little piece out of the ring , and burning my finger. I took the ring off my finger and stuck my hand in the snow. Super nasty burned.
I have a 2003 Chrysler Voyager LX and my ECU has went on it and needs to be replaced, can you hook me up with your friend Charles so I can get a new re-programmed ECU for my van, I would greatly appreciate it
I would like the same please
THANK YOU VERYMUCH
Hi, Thanks so much for this video! Will you tell me what problem(s) you were having with your van before you replaced the ECU? I have the same van. When I start mine and put it in reverse or drive it will move about 4 feet and then cut out.
Check the distributor rotator cap and spark plugs and cables.
3 days to program? Huh. They need to be "flashed" at a shop. Carquest does it. But if you get a salvage yard ucu the be surevto get the VIN off that car. The shop will use that to program fit to your car.
Idk if carquest bought advanced auto or vise versa but Ik know advance auto that only sells CQ now but they don’t flash them .. with mine being 2001 DGC they claim it too old to flash, they don’t have the software.. I floored that’s insane if u do need flash that u can’t in Ohio here..
AWSOME 👍👌👏👏👏👏👏👏👏👏👏👏👏👏
Wow, you didn't even disconnect the battery. Also, did the light every come back on...like 2 weeks later or something? I would be disturbed if the part numbers didn't match up 100%
By now you probably sold the van, but I had similar trouble with the ac due to a TIPM issue..
This series of caravans had bad fuel injection engine harnesses. Hard to find must cut the harness open and take a look at the main plug
What can be done to fix it
@@kolriehill7082 You can (or could) buy the complete fuel injection harness from eBay. It was 125 bucks and not hard to change, plus at this time you can relocate the harness away fro the exhaust. Amazon sold them also....
what went wrong that you needed to replace the ECU?
How was the van acting before you replaced the ecm...? Think I may have the same problem... I have 2001 chrysler voyager 3.3 blowing out black smoke idle is bad acts like misfire.
Check the thermostat inside the glove box for fan setting on high
Where can I find Charles? I need a plug and play PCM
What issues were you having before you changed your ECU? My car won't start, but every other part related to the ignition is good. Battery, fuel pump, starter, and alternator. I have code p0401, I failed the smog test. I'm about to replace the EGR valve and the vacuum hose.
Did u find out if it was the EGR? I have the same code and I replaced mine since it was the original.. but didn’t fixed it .. did u find out what’s wrong with it? I have 2001 ..
@@theresam8809 The main wiring harness was burned through the wires, because It was resting on a manifold; and that caused the ECU to burn out, so I had to replace both. Car is running fine now.
Thanks
Stuck with a fried ECM in a small town in the bush of Northern Ontario. No Dodge dealership anywhere remotely close to even reprogram an ECM with part number P04727318AC even if I purchased a used one online. Any help would be much appreciated as we are a family of 5 with 3 young boys, all under the age of 5 and desperately need the van!
Justin, I'm looking for one for my mom's 2005 Caravan and came across a website that sends them to you pre-programmed after you supply the pertinent info. Good luck ... carcomputerexchange.com/contact-us/info_2.html
HiBuzz52 Thank you. I've already resolved the situation thankfully, but appreciate your response. Merry Christmas!
@@justinh.8019 what did you do to solve the problem
I have the following situation: Only the passenger side headlight is ON. When I switch to high beam, only the driver side headlight is ON. When I switch high beam off, again, only the passenger side headlight is on. The lamps themselves are fine. So what could be causing this? Do I need to replace the Front Control Module?
Try switching the lamps. Put the left on on the right side and vice versa. What is the behavior when you do that? There may be 2 fillaments in each lamp...and both lamps have a broken fillament?
@@LivingInAVan I finally figured it out. On the front of the actual fuse box (they call it IPM - Integrated Power Module) there is another module called the FCM - Front Control Module. It is attached to the front of the fuse box with 4 torx screws so you need a special screwdriver. By the way you have to remove the battery first so you can pull the fuse box out, which is done by inserting a flat screwdriver on the side of the fuse box and twisting, the fuse box then tilts, and there are light grey clips under there to release the other side under the fuse box. Anyway once you have the fuse box tilted up, you can remove the 4 torx screws and remove the FCM. There are a bunch of pins connecting the FCM to the fuse box. Some are round and the bottom ones are flat. The flat pins need to be twisted slightly and cleaned, so they make better contact when you plug the FCM back in and put the 4 torx screws back. Then re-attach the fuse box, put the battery back in, and it's fixed. Basically just a bad connection with those flat connector pins. Hope this helps someone in the future!
Can I ask if you put a scanner on it first and if so what code was popping up? Was it a code p0601?
Do you still have a contact for Charles? I need the same thing.
ALWAYS disconnect the battery before working with electrical components....shoulda described what was required to obtain the new unit....i.e....vin # and such....
Why did you get a new ECM?
dont you have to program the new pcm
Yes. Charles had it programmed before sending it to me.
@@LivingInAVan you repair ecms?
Where did you get your pcm? I just found out that I need one, but the mechanic says it has to be sent off and rebuilt for 260. I am praying for a miracle! I'm already having to put almost 700 in my 2003 Chrysler Town and Country, before the computer problem that my mechanic says happened whe he plugged in my fuel injector!!!
I do have question on anyone have issues of radio and CD player not working out of the blue when turn on my radio which is connected to the clock it starts blinking and my CD players acting like it try to eject.. until I turn off the radio, but even when it off sometimes it auto come on and starts the blinking light on clock and sometimes it do like static sounds, I’ve took out the radio and no missing or cracked or bad wires.. on top now if turn on my car to start b4 it did b4 crank the blower turn on auto too..
Maybe I have a ghost inside lol.. any info appreciated..
Sounds like you have a bad connection and the power to the radio is going off...then back on. The bad connection may be inside your radio or even the power line that runs to the radio from your car.
Can you give me some advice on my 2007 Chrysler T & C
Double-check the distributor and the spark plugs. The Power Steering Reservoir on these models like to leak all over the spark plugs causing misfires.
Hi I want to do the very same thing with a 2003 chrysler town and country.Hit a deer recently and messed up the pcm. are refurbished computers on ebay a good way to go? any help in
pointing me in a good direction would be greatly appreciated
You have to have it reprogrammed with your vin. My problem ended up not being the pcm but the ignition coil and sprk plugs/cable. The power brakes resevoir leaks and drips onto the coils causing misfires.
@@LivingInAVan yes thank you I was aware of the VIN/ programming and was just checking if anyone else had another pcm programmed thru buying it online with good success.There are some that do it thru ebay
ok thanks
how can programming a new ecu with different number for dodge caravan 2002 ?
www.solopcms.com/blog/dodge-pcm-reflash/
Why does it only blow on 5? Mine does the same
I think the location allows the fluid from the power steering reservoir to drip down into it.
Charles help me plz
I have the code p0601 but it still runs but runs bad.could you get me some info of the guy you got it from an how much it cost.thank
Usually $200-$1,000 for the unit. Then it has to be reprogrammed with your VIN and installed. Is yours a dodge grand caravan around the same year? You can have my old one for FREE just pay for shipping. It would need to be reprogrammed with your VIN. I think my old p.m was fine. The issue causing the problem was one of the injectors wasn't working.
@@LivingInAVan do you still have the pcm? I'd buy it
Hi I need one can you help
DRUM ROLL PLEASE LET SEE 🤗
Where to purchase ECM
Junk yard or online. It will need to be reprogrammed with your VIN for your car/van.
Check the antifreeze.
Thank you Charles. Thank you God.
Little Blue Two,
We Love You.
