After cleaning out both the connector from the wiring harness and as well the 4 pins of the relay, I'll see what happens. Again, I could have remedied the problem by cleaning the relay contacts. From reading posts, I'll also try turning on the AC and seeing if all fans come on.
If the relay you cleaned was the coolant fan relay you can jumper A to D and the fan should run. The relay is also fused so you might check the fuse BUT I believe the fan and AUX share the same fuse so I'd think that's NOT your issue. Jumper to the motor to see if the motor is good. Does all wiring appear to be original?

Do you have the FSM for your car?

Hey "Seabright" how are you? Good to see you around!

I noticed there had been a few posts through the past couple months and I thought I'd just try to accommodate the "newest/most recent" poster rather than just mention to "START NEW"!
