Hey guys. I have an 07 H3. Awhile back both my side mirrors quit working all the sudden. They are just power mirrors. Coincidence, the sunroof controls have quit working as well. By pressing the sunroof button I can open and close it however the automatic one touch button for the sunroof doesn't work....I have to hold the button down to open or close it. I have checked all the fuses and cant find anything wrong with them. Any help would be greatly appreciated

 

Start by checking / replacing fuses:
#9-15A(sunroof module,turn signal/multifunction switch, AT floor shift control)
&
#56-30A(mirrors, Front turn/hazzard/courtesy:BCM)

______________________________________________

#57-15A(sunroof motor) Good.

Under hood fuse block, make sure you have the right fuse as fuses are color coded to amps.. GL

 

did you look at the wiring diagram to see if the notorious driver door switch module is involved?
check connectors.
try the old reset trick,unhook the batt,touch terminals together,pray,,,

 

Here's the simple fix for hummer mirrors that quit. lift out the switch module with all the switches on driver door. It juust picks up and out.skin back the orange wire feeding the mirrors..See if you have battery voltage. If not its failed in the bc module. NO BIG DEAL. The other orange wire three inches away feeds the door locks. I ran a jumper from the door lock orange to feed dc to the mirrors. works perfectly. For safetys I soldered in a 3 amp spade fuse on the jumper. works perfectly. 10 minutes.The hot circuit failed in the body control module. if you have hazards and courteysy lights it's not the fuse. it wont damage or back feed cause its open in the bcm.

 

Thanks for the assistance in this 3 year OLD thread.

 

I had this problem and suffice to say I purchased a whole new sire mirror ... set me back $350 bones!

 

i think i paid a yard $125.
always shop yards first.

 

I meant to say "side".
