I have a 02 ram 4.7l and the in cab ac/heaterblower just quit working. I am not getting any power to the switch and I do not have a wireing diagram. I have checked all of the fuses but if someone knows the exact fuse to the blower I will try replacing it in the case that it is a bad connection. The fuse diagram is not that in depth. I am pulling my hair out tried everything I can think of please help.
