I purchased a used 2007 Suburban a few weeks back. And, there are a few electrical items not working on the front passenger door. The mirror doesn't move from the controls on the driver's side door (though the driver's side door mirror moves fine), the heated seat indicator lights don't light up (though I think the seat is heating up) and the auto-down function isn't working for the window.

I'm wondering if possibly there is a fuse that controls some of the electrical stuff in just the passenger door?

Any other ideas where I might look to fix these minor issues?

 

I'd start looking for loose connections. Start with the power window switch. It's easy enough to pop it out and make sure all your plugs are tight. The power mirror plugs into it, as does the seat heater switch.

The fact that the auto-down doesn't work, my guess is the switch is bad, and replacing it might potentially cure all of your ills.

 

Could be the master switch as power runs through the master switch, Chevrolet Suburban Window Switch these switches are functional upon installation except for the mirror functions which need to be programmed with the gm programming equipment 30 day return policy

 

What if I bought a new master switch and it only works on the drivers window but no other window works or the power locks?

 

My issue ended up being that the passenger switch needed to be programmed based on the options that the vehicle had.

If you put in a new switch, it too may need to be programmed. My mechanic said he gets charged $75 each time he uses the machine to connect to GM and program the switch..

 

Dang.. Ok I'll have to keep digging or fork up the dough I suppose.. Thanks for replying

 

I'm currently undergoing the same issue!! Check fuses, check the alternator replace the battery check relays.Check the ground wires replaces the motor and the door is still dead where u able to trouble shoot yours? ​​

 

My ‘06 2500HD doesn’t have auto-up or seat heat. But several years ago the window and lock controls on both doors started intermittent fails. Replaced them, problems all gone.
