Location of the fuse for the mirrors on a 2001 yukon denali

SOURCE: location of fuse box/panel for 2004 yukon denali xl

There are 2 fuse panels in the Denali.
One is a panel on the drivers side, its on the dash but facing the door.

The ohter is under the dash and above the pedals, this one is much tougher to access.

Your Owner's Manual should tell you where the fuses are that you need to access.

the relay is built into the speed resistor or motor control module ) depends if you have automative or manual heater controls. is automatic it will be motor control module and manual is the resistor module. these units are located beside the heate fan motor. the motor helps keeps the unit cool. just unbolt the module, unplug it and install new one. Just check to make sure the connector is good.. The heat created by the connection sometimes melts the power or ground leads (red or black) and if this is so you will need to replace the pin.

SOURCE: How do I remove and replace the power side mirror

2003 GMC Yukon - My power mirrors stopped working.... all fuses have been checked and they are all good. Any ideas? These are the power folding mirrors. The function that allows you to fold them in for car washes etc still works.... they just will not adjust when you change drivers, or when you try to adjust them with the controls. Any ideas would be appreciated!

Seems like a common problem with these trucks. I thought I was the only one. I just posted this comment for someone who has a 2003.....I'm not an expert and not sure how widespread the warning message can be, but in my personal case: I have a 2001 Yukon Denali.....I have the same problem and have for many months. I took it in a few times and the GMC Dealership finally told me that It's the ride air bags. In my case they are leaking. Its not the same safety airbags in the front dash to prevent injury...but these models have air bags under the truck that automatically adjust to level when weight shift...you might hear the occasional sound coming from the back while driving or when more people are in your Denali. To me it sounds like a power tool. The Service tech told me it's not harful nor will it damage anything, but it costs about $2000 to fix, because they have to replace the whole thing. He said you may notice the sound coming on from the airbags more often because of this..because the system is working harder to adjust the weight due to the leak/loss in air. So occasionally for about a year...the light comes on....but it has done nothing else.

I hope this helps.

The security system (Passlock) is having problems, it's typical on those trucks. You can find a great write-up here: http://newrockies.ca , it was the only thing that saved my Park Avenue.
