My seat heater light indicators went out on the drivers side so I ordered a new module. The new module doesn't seem to light up like the other dash lights around the radio although the indicator lights come on when the heater is on. I took it apart and there appear to be light bulbs to illuminate the seat heaters and the traction control so you can see them in the dark but they don't work. Ordered another module from eBay and same thing. 2 modules (plus original) not lighting up, what are the odds or am i missing something?
