Driver and passenger side power mirrors do not function, will move outward, but not in, up, or down on my 2000 GMC Sierra 2500

Question edited for clarity.

This is a job for an auto-electrician unless you can read wiring diagrams.

I had this happen on my 2004 also. I have the climate zone control module that allows for adjustment for driver or passenger temps. I had to cycle between hot and cold on the passenger side and switch it between defrost and feet, then power off everything for a long period of time using the power button on the control, this finally got the solenoid to become unstuck. If that doesn't work then you have to get into the heater/air ducts under passenger side, which is difficult, to manually unstick or replace the locked solenoid.

I would raise the hood and check the powerwindow fuse..

the headlight housing is held in by 2 L shaped pins that rotate outward and pull up and out, then it can be pulled out.

For 2000 GMC Truck Sierra 2500 4WD 5.3L SFI 8cyl the Fuel Filter is located: Under vehicle, driver side, below seating area, near fuel tank, mounted on frame rail in fuel line.

Hope this help (remember comment and rated this post).

You should be able to replace the glass, but I believe it is glued in place. You should be able to tell as you remove the old pieces. It is a special white glue.
I was able to get a great price for the whole mirror on ebay. even the ones with signals and heated.

Hope this helps

sounds like a switch as common error oboth sides unlikely

FUSE AND MAYBE LOOSE WIRE CONNECTION

I just spent about 2 hours trying to resolve the same problem, and discovered that there doesn't appear to be any way to repair the mirror without purchasing a whole new one. There a 3 screws you can access by slanting the mirror to the extemes in both the up or down positions. Once they are removed I discovered a 4th screw (once I broke the plastic pieces surrounding the mirror appart) that there is a 4th screw that is impossible to reach without removing the actual mirror part. In any case I discovered that the reason that the mirror was floppy is because there was a funny looking nut that is supposed to lock in the spring mechanism that was completely stipped and non functional. Better luck than me!

go to a glass shop they will replace just the glass I just had mine done
