SOURCE: 2004 gmc canyon fan moter for ac dont work

There is a fuse I would check first if you haven't tried that yet. They had problems with the switches in some of those vehicles. If you could take the control out and unpug then reattach the plug it may start working meaning the switch is bad.
You may have a bad fan motor. Do you have a test light to check for voltage at the motor itself?
Lastly, there is a resistor set that changes from low to high that may have one or more resistors burned out.

SOURCE: abs

Disconnect the positive lead on battery wait about 30 seconds and reconnect. Take it out somewhere where you can floor it and go through the gears a couple times. This will clear error lights and establish a new acceration curve. If the error comes back then start looking for loose connections or alignment problem for abs stuff.

SOURCE: heater fan only works on the high position?

There is a plug up under the glove box that loosens and you need to snug it up.

There isn't one. There's two fuses for the turn signals. The flashing is controlled by the Body Control Module.

you probably have corrosion in the power train control module and connector.it is located under the hood on the passenger side on the fire wall.remove the connectors from the module and clean the connectors and module with a soft brush and spray them with electrical cleaner.i have seen this problem before.

Reduced power


This is what is called 'limp mode', the computer detects a problem, and to avoid damage to the vehicle, limits the power, and kicks on the check engine light. Bring it to a parts store where they will plug a hand held scan tool into the truck's diagnostic port, check for codes stored in the computer, and tell you what they are, what they mean, and suggest a fix(es) for the problem. This is a free service at most stores. If you still have questions, post them and the codes here for further help.

2005 GMC Canyon engine dies while im driving


Sounds like it may be a loose wire or connection that reacts at a firm bump. I'd check at the starter, and coil. Also check the battery ground at the body and block connections. Hope this will help. Best wishes.

Our 2004 GMC canyon will not start from time to time.


sell the truck and get one that does not have the security system that locks out the engine starting. I wish I could but I can't for a year or so.

Brake light switch


In the 04 models there has been a recall on a part in the brake lights. You can look it up and it gives you a number to call GMC. If you truck is one of the affected models they will replace it for you.
