My power fold mirrors are dead

[08grey]

Anyone ever have the power fold mirrors just have no power? No response to the switch, happened all of a sudden all other electronics seem to be working fine? Any help would be greatly appreciated.

Check the fuse. #14 on the dash fuse panel is for power mirror

Does all the other switches on the door work (windows, locks, mirror adjust)?

There is a fuse for the drivers door module, not sure what all that controls, but it's #4

Everything works but I also noticed my radio won't turn on when the key is in the on position only when the truck is turned on.

Notice any loose wiring under the dash? They can get knocked around easily. Might also see if you’re getting power to the fuse location. Can you hear the mirror motors trying to work? I wouldn’t think both gears would fail at once. You might also check your ground cables under the hood.

Also check under the driver's door underneath the body there are 2 grounds to clean.

I cleaned those after my stereo lost power and works great now

Just got my stuff in to fix my yukon. I am removing the poor ground for the battery with new #2 guage cable and other ground under the hood. As well the transgo is to fix the soft shifting my yukon has had. I have to let off the throttle to get it to shift.

I was informed to use welding cable as some automotive supply places will have copper coated aluminium. This stuff will withstand 2000 amps for just the battery ground. The roll of 20 feet wasn't too bad. About 60 bucks

Just need some wrenches and sandpaper or a dremel like I used. My cd changer never worked but lost power to the stereo and the mirrors would lose power intermittently. Just clean the 2 grounds under the driver's door. That should help. Mine were rusted bad. Soon as I did that power all the time now. Oh and there is another by the driver's side driving light. Clean that one as well it was rusted on mine bad. The computer grounds there.

What are the trouble codes stored in the BCM?
