No They are heat sealed Job for glass specialist

I would guess that your blower motor is toast.

5 1/2" bolt pattern: 4 1/2 backspacing, tire size for winter tires is 235/75 R15

you'll need to remove screws that are by the door handle, arm rest, under door and side of door and then gently pull back on the panel as there will also be retaining clips attached and you don't want to break them. Then pull back the weather seal (can't reuse it, but it's not that important) and you will be able to access everything.

Check the blower resistor pack - usually located in the heater air ducting in the blower fan airflow. Check for loose connections and open circuit resistors on the unit.
If speed 4 works always, its unlikely to be the blower motor ground connection.

The fan may have to be replaced. Do check the back of your control switch to make sure all vacuum hoses are connected.

If it's an Automatic and you have a check engine light on, it's best to have the the 3/4 shift sylenoid checked out.

Replaced connector and everything is perfect. Several canyons have had this same issue . looked through several forums. Thanks Guys

It has to be for the 2004 Canyon.

Hi there,

Fan Blower - First turn the fan on low or med then tap on the heater motor w/ a screw driver, if it try's to turn on or does turn on its the brushes in the motor (thus you need a new one). Second you can try testing the switch w/ an ohm meter to see if the switch is burnt out. If this doesn't fix it then your into relays and such.

Sunroof - There are cables on each side which pull the glass when moved in sync. The cables have slipped out of sync. The sunroof frame will have to come down and probably replace the cables. If you are handy, take the glass out, run the motor to the "closed" position. Remove the motor. Pushed the slides to the fully closed position and re-install the motor. If the cables are okay, this should put them back in sync.

Emergency Brakes light - It's used to indicate that the parking brake is "ON" and also to indicate that the brake fluid level is below minimum level. If your parking brake is indeed off then check the brake fluid level. If it is near minimum it will sometimes flicker on & off when your car goes up or down hill. With disk brake systems the fluid level goes down as the pads wear. By the time it gets to minimum it is a good bet you're about due for new disk pads. It's at least a good idea to have them checked. Replacing the pads will expand the calipers pushing the fluid back into the reservoir and curing the low level.

Its better to Do Some Maintenance on your car....
Good luck...
Thanks

brake light switch,replace it
its under the dash at the top of the break peddle takes about 5 min too change

You probably have a screw in a wire that grounds the connection turning the light on. The white wire will be the one that the screw is in. The orange wire is a 12 volt wire so it can't be shorted because of a blown fuse.

do you have the key , or the key less entry?

using keyless entry wont work you need to use the key it self.


here is how a car thief will do it.

1,) crawl under the hood and locate the lock for the hood. it should be just behind the radiator.

2.) stick your hand up until you feel the cable.
you have 2 choices..
a. cut the housing from the cable and pull the
cable itself to open the hood
b.) trace the cable up until you find the lock the
cable pulls and use a long screw driver to
pry it loose.

or.

1.) remove the driver side tire. (yes jack the car up.
2.) reach under and locate the main harness.

3.) locate a red wire in the harness, A THICK WIRE OR THE MAIN POWER WIRE.

4.) splice it, connect it to another battery POS terminal. connect the negative from the battery to the ground of the car. Now you have power :)

Warning using the wrong wire will blow fuses.

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.

it sound like it may be a fuse the fuse box is either under the dah or in the engine compartment. if the fuses are ok you may have a bad earth you can test this with a multi meter.
iff you are still lost get back to me hun and i will see what else i can do keep on trying and good luick Lindz

Well not being and expert! I fixed two of my gmc's but you need to get under the car, and check the points of contact on the harness, both of my trucks had corrosion on one contact point, so I cleaned them, and stuck a short piece of copper wire in inside to insure good contact, check engine lights are off on both trucks now!

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.

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.

the heater motor should be located on the passenger side either under the dash by passenger's feet or under the hood on the firewall(wall closest to the windshield) there should be a wire or small wire harness going to it .
looks like half cylinder bolted to firewall
