I just remembered that last year I had to have the dash and heater box removed to replace one of the doors. Maybe the shop didn't get something right when they put it back together and some wire has worked loose. Jumper wire is a great idea--I'll give it a try if I find the ground.

 

Hi I am new to this site and I am having the exact same issues with the blower motor, door locks, dash lights, ..... I was wondering if you had figured out what was wrong with yours any info is appreciated.
