Cadillac Seville / Cadillac Eldorado Forum Discussion, 1995 eldorado fan blower problem in Past Cadillac Vehicle Discussion; OK, these are the things I have done:
Checked all fuses in engine compartment and trunk
Replaced fan motor, because ...
Well, hopefully someone will respond some time. I see 111 views and no reply. I have an update.
I puled my new blower fan and decided to bench test it again. Well when I connected the battery positive to the blue wire on blower and battery negative to black negative blower wire nothing. So for kicks and giggles I switched my battery connection around and the fan spun. (put battery negative on blue wire of blower and battery positive to black wire on blower) What gives???
Hopefully I can get some type of response from this forum. Thank you in advance for any information or help.
I reversed the positive and negative wires on the blower and plugged it in to the car. The fan turned on as soon as I had the connector plugged in. The car was not turned on or anything, so that is not the problem. I have since switched back the wires on the blower. I am getting power to the red wire on the blower plug and the black ground wire is working also. I jumped the red to the black wire and getting power. I know the red wire is always hot and connecting it to the black wire confirms hot wire and good ground. I am inclined to think it is the climate control module (middle wire), but how do I test. I don't want to spend more money on something I don't need possibly.
