Hello,

I am a Newbie to this forum traded a Trailblazer for this Avalanche. I had pedal adjustment, mirror adj. drivers side heated seats, mirror pull-in both mirrors, and puddle lights. All have ceased to work--fuses seem o.k.

What to do?

 

You are going to need to get an electrical diagram, a test light and a dvom then start testing. Try to find the common denominator between them. How did you check the fuses. Did you check every fuse inside and under the hood?

 

not sure what is pm?
