Using my volt meter, I checked for voltage at the blower. With the fan set to the highest setting, I saw 12 volts so I thought the blower motor was bad replaced it.
The new motor ran for 5 seconds then stopped. Still getting 12 V at highest setting and 6V at lowest fan setting. I've read that if the resistor goes bad, the fan will operate only at the highest speed, however mine doesn't operate at all.

It is the SE1 model and doesn't have dual climate control nor the heads up display showing temprature. The problem that I am having is the the Compressor clutch will not kick in toturn on the air. I checked Ra levels and the system was full, so I replaced the AC Pressure Sensor thinking that it was the problem from some other threads that I have read and it didn't change a thing.
I checked all of the fuses and the are good, I even replaced the Relay in the Fuse block and still no cold air. I took off the outer casing to the relay and manually forced the contacts shut and then the clutch kicked on. I pulled out the relay and it isn't getting the grounding pulse that triggers it to kick on. Does anyone else know what else I can check? About the only thing that I haven't done yet is pull out the cluster to see if the switch is working, I am just taking it at face value that it is working since the light is coming on.
Any help is greatly appreciated. Just bought the car 2 days ago for my wife and she is ready to put it up for sale. Thanks Allan. Could be low coolant or blowen fuse, I'd check coolant.
Good luck. Even if you replaced it, you could have gotten a bad one. I checked the coolant and it was up there and all fuses seem to be good. The other thing that I noticed is that the Cooling fans don't come on when the AC button is turned on. Which 2 wires do I jump. My sensor is a 3 wire sensor.
