Bought a 15 passenger Ramn Van 3500 in april . Fixed both AC units and Rear air worked great but only on High. I bought 2 resistors and changed front never could find the rear one .. It worked on high for a while but finally just crapped out . And does nothing .

Help I can not find the resistor for rear AC. The parts place said it was same as front and I see nothing that looks the same anywhere !!!

Help
