Condenser fan not working. Checked fuse and relay they ok. Changed transducer switch and still nothing. Ran jumpers to fan from battery and fan works. No power to fan at plug at fan. System is charged fine. Compressor runs and cycles fast due to building high head pressure. Any clues to why I can't get power to fan???

 

Sounds like you've narrowed it down to the cable. Run a continuity check on the cable conductors.

 

Could be pdc also if the year of the truck falls right

 

Well I turned ac on and while compressor was running I put test light on prongs of relay by pulling it up a bit. Got power on 3 legs while compressed is on. So I guess I got a broke wire somewhere. I pulled fuse box out and traced wire from fan up to fuse box but it goes into a cluster box of wires on fender. Don't know how to find it.

 

Matt,
You really need to post up the year truck you have and the engine package. The computer controls for these trucks vary greatly from different years. Its much easier to find the stuff in the FSM, but really need more info to help

 

It's a 2002 ram 1500 3.7L auto trans.
