I noticed my heater control has a penta-star logo on the back. Does that chrysler logo mean this part is common to other chryco products? I want to try and get the circuit board at a self service junkyard. They think loose boards are "miscellaneous" items, and price them real cheap. Once I have it, I will experiment with boring holes in the light bulb location and inserting standard illumination bulbs in place of the stupid soldered in ones.
