Hi there! Sounds like the power transistor may be to blame. Before you point your finger at the blower motor, perform this check.
Wire colors are black/yellow and black
Disconnect the 4P connector from the power transistor.
Measure the resistance between the No. 3 and No. 4 (4-door) or No. 1 and No. 2 (2-door) terminals of the power transistor. It should be about 1.4-1.5 kW.
If the resistance is within the specifications, go to step 3.
If the resistance is not within the specifications, replace the power transistor.
Where is the power transistor located?
Here is the graphic that includes it's location. You can see it if you look from the passenger side under the dash. You may have to drop the glove box down by un-clipping the support strut on the right side of the box then pressing in on both sides.
Ok, Here is the deal. I feel like an amature. I replaced the power transistor unit, but pryor to complete installation I ran it to see if it would work. It did, for about five minutes then shut down again. I realize the air in the A/C unit acutally cools off the unit. Did I over heat it by running the A/C without the power transistor installed correctly in the air path? Or is there possilbly another problem?
