No, switch pod checked fine. It outputs the proper voltage to the HSCM.
I do believe that the seat switch puts out 12v to the HSCM instead of the 5v that I had read. I'm going to do more investigating on it Sunday when I get off shift. If that is the case, I'm going to try to install the aftermarket seat heaters.
