BillWill, the wiring diagrams show 1 connector for what looks like the A/C fan, from what I've read, all the CRD's had 2 electric fans and the mechanical. I've got another plug coming out next to the front A/C fan connector, I assume it's for the other fan. Need to find the female side or make my own. Not sure how to test that connection, wiring diagram shows a low and high speed relay, presumably in the power distribution module..going to need to dig deeper into the manual to figure this out. The connector shown in the manual looks similar to the one on the fan, different from the one I found.
Thanks for the help..
The CRD has one electric fan with two speeds. There is a High Speed Relay and a Low Speed Relay in the PDC under the hood.
What year is your CRD...so I can look up the correct circuit diagram!
Looking at the 2005 CRD circuit diagram (8W-30-37) the fan should have a Black wire for the fan ground, a Dark Green/Dark Blue wire for High Speed and a Dark Blue/Dark Green for Low speed.
The ECM decides which of the two relay coils to supply ground to so either high or low is activated; fuse 2 and fuse 16 need to be OK.
If you remove the two relays you can jumper pins 30 and 87 together in the relay socket of the Low speed relay and the fan should go at low speed. Remove this jumper and put it in pin 30 and 87 of the High speed relay and the fan should run at high speed. The two relays locations will be marked on the Lid of the PDC under the hood.
