Hello, I have a clean 96 Eldorado with only 25,000 miles on it. Looks great, runs great, but the A/C blower motor quit on me, at least I think. When I purchased the vehicle the previous owner mentioned that the blower motor quit working and needs a new one. Ok, so when I brought it home, I started playing around with it. All fuses were good, and I can hear and feel by the vents a slight coming and going noise as if it wants to kick up but it doesn't. This is intermediate too. I disconnected the wiring harness to the motor (Red/Black/Grey wires) and I have 12 volts to red using the black wire in the harness as the ground and it shows .02 to .03 on the grey when I have the dash controls on High A/C. The blower kicks up so very slowly for a couple seconds then stops. It repeats this. Even when the ignition is Off! The next day I went out and started the car and everything worked perfectly fine for a couple of weeks. Now its back to doing the same thing. This time I ran hot from the battery directly to the motor where the red wire would be, same with ground. Leaving the grey wire disconnect, the motor will slowly wind up a couple seconds, but very slow, and stop again then repeat. I then ran 12 volts to where the grey wire would be on the blower motor and same thing. Now I hook the harness back up, probe the wires while everything is on and now I'm seeing 18 volts to red and grey?! I'm at a loss, please any info will help. Thank you. Steve

 

It turned out to be the blower motor
