Mirrors not foldinh
Hi there just wondering if you fixed the problem yet ? I have an 03 tahoe with the same problem. Thanks
I finally solved the problem.
There are various solutions out there. There is a TSB that suggests the mirror folding system can just get out of sync. To correct this manually fold the mirrors and then use the switch to open them. You should see the mirrors open and then hear them click into place. The solution then requires you to cycle them 3 times (which I assume means open and fold 3 times) before switching off again.
However this did not work for me.
The clue to my problem was trying to set new postions for the mirrors on the 2 drivers settings. If you are not familiar with this just set the mirror to a postion and then press and hold either button 1 or 2 - you will hear 2 beeps when its memorised the settings. You need to set distinctly different postions for the 1 and 2 buttons for both sides.
The idea thus is hit button 1 (driver1) and the mirrors should move to the memorised position. Then hit button 2 and the mirrors should move to the other memorised different position.
However in my case the mirrors didnt work as they should - the drivers side did but the passenger side didn't move.
This is important as the folding mechanism first centers the mirrors then folds them - if it cant move the mirrors and get a signal back to the driver's door module that they are BOTH centered then neither will fold.
Having found the probelm was in the passenger mirror I then carefully pulled at the glass and it eventually popped off the round mount at the back. Be careful as the mirror will have wires to it (well if its heated) so support it - be careful as if you fold it you may jam the glass between the body and the mirror mechanism.
In my case a large rubber boot that stops water and dirt getting into the mechanism appeared to be out of place. With the mirror off I cycled the mount (so selected the mirror switch to passnger side by depressing the right hand side of the rocker switch and using the 4-way switch to move the mechanism up/down/left/right). The mirror movement did seem slow but quickly improved.
I popped the mirror back onto the mount - there are two half moon cut-outs you need to align and its just a hard push.
If that doesn't solve your problem then you can get a technisican with a TECH 2 diagnostic scanner to force the mirrors to move - that way you can identify if its the mirror or the wiring or the modules.
By the way the other thing I did was to pop the plastic trim off the inside of the passenger mirror on the door - just pull the front edge and it will eventually pop off (I was worried I was pulling so hard but it was fine). I made sure the wire cable bundle was Ok and not rubbing.
Let me know how you get on - or if you fixed it already,
