I just replaced the blower motor resistor, which works fine now, and noticed the driver's control of the other 3 windows quit working. At the same time, the power locks quit working (via either switch or the key fob) AND the interior lights do not come on when any of the doors are opened. The lights on the bottom of the individual front doors DO come on, but not the interior lights.

We also noticed the gauges on the dash also jump for a few seconds now when the car is turned on.

I thought I might have unplugged a wiring harness during the resistor replacement, but have checked this. I also checked the fuses.

Any ideas? Thank you.

 

Just to clarify; the front passenger's, right rear, and left rear windows all work from their switches, just not from the driver's master window switch? Also, is the driver's door lock switch the only one that doesn't work? Do the other locks work from each of their switches?
