1995truck
Newbie
I was at the pick a part today getting some small parts for my suburban. I was working on a 1997 suburban when behind the dash I found this odd looking part, it was bolted to the tube dash support in the center area. I know its some type of resistor with a large heat sink. It had a number on it 10094705, so I googled it and it came back as Resistor Rectifier. What is this used for. I have not been able to find it on the wiring diagrams. I know its not the blower motor resistor. I'm sure on of your guys know what it is.
