There is a step that is crucial to this repair that is not mentioned in most of the videos in regards to the resistor. The reason these harnesses are shorting out and getting too hot is because of a bad design in the ground wiring. Under the hood on the upper portion of the passenger side wheel well just behind the air cleaner cover (which you'll need to remove), you will find a bolted harness attached to the side wall. This harness includes a good amount of your ground wires which includes the ground that comes from your blower resistor. Chevy for some reason decided to mount this ground wire harness to a PAINTED piece of metal, thus not allowing it a proper ground. Remove this harness from the wheel well panel and grind off the paint from where it is bolted on to using a tool such as a Dremel. Also grind off the paint from the grounding harness itself where it will be attached to the side wall. Once both the harness and the side wall have been ground free of any paint, apply some electric conductive grease on the area before re-attaching the harness to the side wall. VERY IMPORTANT YOU DO THIS! IF YOU DO NOT.... YOU WILL JUST RUN INTO THE SAME PROBLEM IN A SHORT PERIOD OF TIME!
2008 GMC Canyon. Exact problem and the third wire was burnt as shown. Just replaced mine in less than 20 minutes. Works great. Thanks. Have not performed the step to remove paint under the ground wires as stated below by TJ Jones.
@@opera93 I have not had a problem with it since I replaced it, 2 years ago now. My how time flies. I used all the parts TJ recommended. I did leave the wires a bit too long, I was chicken to cut them off. 1 note: Add some shrink fit hose on wires and heat to shrink. I wish I'd done this. Good Luck, Jay.
jaime sosa I’ll look up a diagram of the fan control an see where 4 goes through an let you know what I find. Basically just tracing the wire back and checking for continuity from wire to wire am seeing if something might be burned out if not getting a good connection
Me too, i have 2007 CANYON, *& ::: random no start engine “” occasionally , & 10 min later STARTS“ , and FAN SPEEDS 3-4 stop a lot…?.HOW DID YOU FIXED.?
@@opera93 Jay here again. This is the security system in the radio. I think it even says in the manual that you have to wait the 10 minutes for the system to reset. It does suck. The only way I've found around it is to have a booster pack available and jump the truck as if the battery is dead. Good Luck, Jay.

@@opera93 There are ground wires on the fender under the air box on the passenger side., grouped on one bolt to the fender.. That ground is bad. Take them 4 wires out and clean them, and sand the fender, as there is paint from the factory under the bolt of the ground there. clean that , and the fan will work again. Also ,on the battery side there is another ground, with 4 wires. this one controls the pass code, and this is bad also, clean it, and your truck, will start every time... Stan from Hawaii Found this from another brother on utube.... let me know... most mechanics don't know this.
Find the ground wire on the fender by the air box on the2007, and clean the ground wires there.. This is why the resistor keeps on blowing wires.... Worked for me. There is a bunch of ground wires on the other side by the battery too. Fix that bunch of ground wires. and fix your ignition problems. let me know if it works. found on u tube from another brother
I cleaned the grounds under the hood as discussed below, and reused the resistor. I was able to remove the other three wires from the original socket and insert them into the new socket, so I only had to splice one wire. Preliminary tests are it is working - will report back if there are any problems.
BEFORE you go through the expense AND frustration of all this work, do yourself a BIG Favor and start where this repair is easiest and may result in making all of this Unnecessary. Locate your grounding module on side panel next to the Air Cleaner box. Unbolt it, then open from the top to access male & female connectors for a self servicing cleaning inside. Use some "Brakleen" or similar solvent cleaner, spraying down into the female contacts using small straw provided. Spray clean the lid's Male spade connectors as well, then spray into the mounting bolt's threads and let everything thoroughly dry (About 30 min). Reassemble and be surprised. Worked great for me and will probably for you if a dirty ground is the main problem.....
This is the problem.. I did this and it worked for me. Got all speeds back on the fan... There is also the same crazy ground combo wire bunch on the battery side, and I took brake clean, and did a cleaning on all the spades, and sanded the fender, and rebolted it to the fender... Fixed my starting problems.. My 07 colorado starts everytime now. Stan from Hawaii
@@jumpsouth1 ------Glad you have found success in the deep cleaning method that has worked for me. But I find that new contamination builds up again after just a few months requiring attention again. All my issues have been with the module behind air cleaner box. My plan is to replace the entire module soon. I'll first remove module from fender, cut off wires at mod, then strip back the insulation from about 3/8's inch from the wires ends that once plugged into module. Crimp bare wire ends into plastic sleeves collars of either ring style or slot type new terminals (heat shrink best for sealing) and slip over bolt (better to use a NEW one) that fits the screw hole at fender with star washer for enhanced contact. Tighten bolt as necessary . This method is the simplest if you don't want the hassle of incorporating a small grounding bus bar like others have utilized......
The best and cheapest (almost free) way of fixing that is to get rid of the socket and solder the wires straight to the terminals on the resistor. Most likely the resistor is still good. Thats what I did and I haven’t had anymore problems.
Thanks, interesting,,, how is it doing now, … I have 2007 Canyon, & like vehicle, and FAN SLEED 3,4 Seem to OFF quickLY:: BUT 1,2 work…..thouhg Memory has LOW SPEED 1or 2 quit sometime?? *****Interestingly, just have a “”NO START , Engine turnover works, no CHECK ENGINE LIGHT, no smells””,& starts 10 to 50 minutes later perfect ( good condition, fuel filter 60,000 mi plus, Running 91-95 Octane ALCOHOL free until I put **Fuel Injcetor “PEA” in gas *&;run through)………runs good, @19/mpg, & good maintenances….
I have/had the same issue on my 2008 colorado but now no setting 1-4 works. No air is blowing at all. Do you know if it's the same problem or something else?
I have that sAme problem and it still wont blow. I chNged tje resistor, I changed the wiring harness and it still won't blow then I changed the actuiator so it blow air then it stopped again then I changed the blower motor and still won't blow now it pushing me to change the AC controls next
Same problem here. Replaced all and it worked for 3 days. Now nothing... Sick of this! I want a fix! Its to cold to have no heater and to hard to drive with no defrost!
I just had that done and it dont work again...Went out coming home from hunting..Not a good time for blower motor to go out...Really sucks bad..Time for new blower motor i guess.
1,2,3 speeds don't work. I only have 4. I checked my resistor and harness and everything seems fine. Is the problem with the blower? Why would 1,2,3 speeds not work? I'm going to buy a new blower. If that doesn't work I'm lost...
on my truck for some reason the connector is lose and cause 1,2,3 to not work.. try turning it to 3 and jiggling the wires if it comes on bad connector
My harness from the resistor is fine. It seems when i wiggle wires there may be a shirt somewhere up by the glove box. It will work then shut off. I wonder if my resistor is bad. I doubt it though cause my wire harness is not burnt
+bill lamonte ok i can help u. like i said its recomended buy new harness because the heat from the resistor always damage and deform the plastic y recomended change harnees and for sure its ur problem
The problem I'm having is I replaced the resistor and it work fine for a little bit for some reason it come and goes check all the ground and fuse can't figure out
Make sure it's not loose. I assume you may have already done it but just double check. If it is coming and going then either you have a loose connection or it's melted again. It's a very common problem in these models of vehicles. GM is notorious for their poor designs. It's not impossible that it overloaded the resistors again. 3 will do it A LOT so if you get it fixed again, avoid using 3 if you can. IF it is working without a problem on 4, then it's either loose connection or melted. Sometimes you need to check your wire to make sure it didn't damage it down the line.
Saint Michael there’s a Colorado site called coloradofans.com that I went to and some of the guys there was saying that there’s a grounding location that’s around the air box on the passenger side that is not getting a solid ground. Because for some reason Chevy decided to paint the inner fender then add the ground terminal. So they say you’ll probably have to remove the air filter box and below where the box was there should be a ring terminal with some wires crimped to it. Unbolt that then use a wire brush or a wire wheel and a drill to take the paint off then bolt the grounding ring terminal back on. Then spray a some clear coat over it so it doesn’t rust. Then put everything back together. I’m sure the resistor might be going out but also do what I just mentioned to the grounding terminal on the inner fender because it might not be getting a solid connection. Also I would add a split ring washer between the inner fender and the ring terminal. That way when you tighten the bolt down, you’ll get a better grab into the metal and it will help to keep the terminal from getting loose over time. I hope that helps.
Hola una pregunta mi camioneta es parecida a esa y no prende el aire y cuando giro el botón para indicar donde quiero el aire solo escucho un ruido y no prende😥
alma disculpa lademora mira creo que es muy facil tu problema solo desconecta el cable y mira si esta quemado muchas veces prende pero no entodos los casos ho y el riudo que se escucha es el motorcito de la compuerta de de cambio de temperatura que elijas frio o caliente, vien cualquier pregunta dejame saber y la invito a suscribirse saludos!!!
Gracias por tu respuesta el ruido lo hace cuando dio vuelta el botón que distribuye el aire a las ventanillas, es un sonido como si se hubiera roto un mecanismo que hace que el aire no salga del blower incluso está sudado como que no sube arriba. Gracias
ok alma bueno entonces tienes problemas con el mecanismo de la ventana de cambio de clima es una ventana y esta ubicada dentro en la caja, su trabajo es dar paso al aire ya sea frio o caliente ocupas cambiarla es muy cumun ese problema ya que son de plastico, pero el ventilador si se prende verdad? solo que no sale correcto? bueno dejame saber cualquier otra pregunta
si escucha que truena algo adentro eso quiere decir que esta quebrado la forma de arreglar seria quitar el tablero y asi llegar a esa caja dentro esta el heater core y el condesador

Thank you! Ive been looking for a way to stop this. Ive replaced everything more than once and it just went out again..

if it wasn't for the fact that mine hasn't been replaced yet, I'd ask questions to see if that wasn't my truck. lol
hey good for you my friend and no its not ur truck probably look same we are in calif. thanks for wach
I know it's not, it's just funny to see one just like it. thanks for the video and replying. will be doing this to mine soon.
