Good job man and ya I've been there before but for changing my ac expansion valve and mine is under the dash on the classic, I had to take all the heater hoses off to the bunk today and now I'm replacing the heater core tomorrow while I'm replacing them. Like you said if you're already doing all that work and in my case draining all the coolant nows the best time. Keep up the great videos man.
Man i admire you...im a company driver but its a mom and pop and we basically talk/schedule work with the mechanic ourselves...the boss just gives the green light, but the mechanic has thrown on a new condensor, compressor, dryer, everything..but he keeps denying its my evaporator! I think hes scared of taking that dash out...its frustrating...i get the metal tube going into the cab freezing up and i also get the fog...if i had the right tools, i think i could fix this!
Yeah the mechanic is being lazy. They don't like taking the dash apart. More than likely that is where your problem is. Good luck to you. It really doesn't take many tools to do it. Trust me, you can do it yourself.
I feel you homie. I do what I can myself. With a little help of UA-cam. I have an a/c condenser, brand new hoses. Ac dryer and a new ac compressor. Bout to tackle it as soon as I run out of my 70 and do it thru my 34. Gna take your advice on that heater core and evaporator. Thinking I should change the expansion valve too. Idk.
Hi, great video , having same if not similar issue , been having costant leaking of freon from behind a/c compressor, changed compressor thinking it was that with brand new one , few months later did the same with new, was your leaking freon from back cover plate on the compressor, also that.noise you were referring to does it sound like a winding noise get louder and louder and comes and goes ? Having same issue never changed evaporator core thinking its plugged up just like yours . Appreciate your help thanks

Is the ac evaporator a pain to get out?
@@robertcordero2134 It's pretty easy once you actually get to it. The most painful part is actually taking the dash apart. Just remember to have the system evacuated before you start. Even if you think the system is empty, just go by a shop and have them be sure it's empty.
If my air only blows cool while sitting you think that could be the same issue? I also have fog blowing of my vents a couple times throughout the day as well.
It could be that or your refrigerant could be low, or your dryer may need to be replaced, could be a leak, etc... it could be a number of things. If you have tried everything except the evaporator and heater coil, then that may be your problem. You will have to explicitly tell your mechanic to change the evaporator coil under the dash because they WILL NOT WANT TO DO IT. They are lazy and the job is labor intense. Unfortunately that is why I had to do mine on my own.
@@natcoziay The refrigerant was put in April so i'd def have to check bout a leak. And i do know my condenser, evap core, and heater coil hasn't been replaced. Im gonna do everything myself as well, i dont need them giving me "the shaft" in labor lol. Preciate it homie!!
@@natcoziay Thank you for replying 👍 I'm having some weird noises coming out of the A/C system I believe it comes from the evaporator, I thought it was the A/C compressor but it is not, the sound comes every time I turn the A/C on and it sounds like a whale crying in the ocean very weird the sound comes and go every 10 to 15 minutes, but the A/C blows very cold the A/C vents sometimes they get wet from the humidity so I was thinking about replacing the expansion valve before replacing the evaporator, I have replaced the condenser and the a/c air dryer couple of weeks ago but the whale sound still there lol, but thanks again man.
When your a/c compressor goes out standard procedure is to replace the compressor, condenser air receiver dryer and the expansion valves and flush the lines.
i have seen vapor and my ac constantly fails it seems to work better on certain areas. im currently havjng to use my rear electric ac at all times while i drive. its a 2018 cascadia. anyone can confirm ehat the smoke on vents mean. it doesnt do it all the times. air does smell or feel a little humid or burnt
Dam im in the same boat. Im changing my evap coil the pipe leading to the expansion valve by the firewall snapped in half huge leak. Its a $300 part one unit and let me tell you its labor intensive. Still trying to figure how to take it off its a 2022 truck. Im 100% sure the lines snap when you drive over nasty potholes. If you cant find your ac leak anywhere check your firewall leading to the cab. If its leaking there well your out of luck and welcome to the party. Im sure this is at least a $2000 dollar job.
@@rigobertoespinoza1685 Yes! It's best to drain the coolant before you start. That's what I did. Also if you can, get the refrigerant evacuated, you definitely don't want that nasty stuff to spew out.
Why did you tear apart the entire dash? I have a 2015 coronado glider and it's just removing the hvac cover in the cab. Change your blower motor filter and get an evaporator cover gasket from freightliner, part number BOA f7928. Bro, you did way too much work, pop the trim panel in front of the passenger seat, remove screws from the lower hvac panel, exposing the blower motor, you can change your evaporator after removing the air filter housing under the hood etc. We change coronado evaporators every two years, my mind is blown when you showed the entire dash torn apart.
I changed the heater core and evaporator core. Didn't know of any other way to get to those parts without taking the dash apart. The key phrase you used is that you do this every two years. I am not a mechanic and have never claimed to be a mechanic. I'm just a guy doing the best he can. Regardless, I got the job done. Sorry it hurt your feelings for me to take the dash apart. Some people always have to complain about something.
Same problem here. I have had everything replaced except the evaporator. Can’t wait to replace it and have an ac that works. Thank you.
Hope it works out for you!
Great job man, I have the same problem 🙏🙏🙏bless you brother
Thank you. I hope you fix it
I have the same truck and the same problem, thanks for sharing this Video 👍

Did you get it working?
@@natcoziay ya I fixed it all up saved a fortune because I deleted everything going to the bunk. One less issue to worry about on the road.
From a diesel mechanic, thank you
No problem. Hope it helped.

Iam about to do the same job Iam replacing every single component on my AC 💯🤘🙏🏼
Good luck to you. Save a lot of money by doing it yourself.
This was a very very helpful video!
Glad to be of help.
Very helpful video , thanks buddy

Thank you for posting this video.
I feel u on that I try to do almost everything my self lots of thieves out there
Exactly
CONGRATULATION, YOU DIDN`T PAY NOBODY FOR THE KIND OF JOB

@@ashmat410 I feel you man...you gotta do as much as you can on your own, especially in today's market. Good luck to you.
Did you ever replace the expansion valve before replacing the evaporator core?
Yes, that was one of the first things the mechanics changed but it didn't fix the problem.

How’s the engine? I just had an American fleet put in my Coronado. 25k miles it’s fine so far.
Solid as a rock, as long as you got genuine detroit parts. I think American Fleet only uses genuine parts.

How you flush the lines?

Good luck to you. Hope you can fix it. It's too hot now to not have A/C
@@natcoziay i got it out just now holy shit man had to disconnect coolant lines in the cab to take the assembly off
@@rigobertoespinoza1685 Yes! It's best to drain the coolant before you start. That's what I did. Also if you can, get the refrigerant evacuated, you definitely don't want that nasty stuff to spew out.
@@natcoziay had none left the pipe nipple was crack.
@@rigobertoespinoza1685 Oh wow. So it all leaked out huh?
Put a shutoff valve on the sleeper heater core also, i was to lost my engine because of that
Lol that’s every shop, you gonna be the only one that cares about your own truck
You are a mechanic
Lol...thank you... I guess !🤷
How bout changing that filthy recirc filter.
Where
I notice so many vids on freightliner trucks and the driver either has no filter or its filthy.

Yep. Many of these mechanics are thieves.
