Rear bower control failure

[75anders]

My windstar -00 rear blower doesn't work. The fan works when hotwired directly and on relay sockets(excludes the resistors?). The relays work separately when tested with 12v on manouver connections. It seems like I get no control voltage to the relays. I do get 12v to the relay mains.
Any Ideas someone?

Are you saying the motor runs if you jump over the resistors?

Another poster had to replace the resistor pack.

No the resistors are fine, so are the relays and motor. It seems like the relays that feeds the resistors dont get there manouver voltage.

The fan doesn't run at all? Or will it run in one speed only? Just curious I had a similar problem with the rear blower not letting the relays close. My fan ran in low speed no matter where I put the blower selector. In my case it was a bad fuse. I have wiring diagrams for 2001 Windstar, if you would like a snapshot of it for this circuit let me know and I will do my best to get it to you.

No It doesn't run at all unless I put a jumper wire over the relays. I would love to get a wire diagram!
