Blower fan not blowing
Hi all. I have a 99 diamante LS with the didgital environmental control unit. My blower motor is is not working. the mechenic i took it to said the blower was good because he grounded the relay and the motor spun. I have also replace the ECU with one from Ebay that was a working unit but still no joy. Any ideas as to the problem or ways to test the components involved? I am an electronics tech so I can do what ever electrical testing needs done.
Thanks in advance
Joe

Turns out, my blower motor was bad. I removed the motor, applied 12 volts to it and it ran intermittently. I connected it to the car harness and turned the switch on but it would only run if I gave it a shove with my hand. Bought a new motor from autozone for 67.00 and now she's blowing like never before .
