Oldsmobile Questions? Ask a Mechanic for Answers ASAP
Hello I will help you with your question,
Are you sure the fan motor is OK?
It is just the control for the fan that is the [problem?
Does the fan run if you turn on the AC or defrost?
Does the AC work?
OK, there are two relays and two fans, the high speed fan should come on when you turn the AC on, does it?
If the high speed fan works leave it alone and just find the low speed wire in pin socket #6 of the blue C1 connector on the engine computer (PCM). Tie a wire into that wire (don't cut it) and to the switch, connect the other side of the switch to ground and it will turn on the low speed fan.
Be sure to turn the switch off with the ignition

I need to know if the fan comes on with the engine running and the AC ON, If it does only use the low speed fan connection.
Look that over and let me know how I can clear up what you need to do
OK, I need to go move a tank so let me know if you have questions
