My '05 Mazda Tribute (just over 200,000 miles) is having problems with the A/C. A while back it was the freon according to the previous owner. I connected a pressure gauge to the low pressure end of the A/C tubes, and the pressure wasn't dropping once I turned the car on (my understanding is that it drops as the clutch engages - if that is wrong, please correct me). So I checked the clutch to see if it's spinning, and it is not. From there I check the fuse, and it is still good. After that I check the relay, and it appears to be good. When I later turned the car off and turned it back on, the A/C clutch was intermittently spinning for a few minutes and then stopped spinning all together.
Here are the three questions:
- Can the power supplied through the relay go in and out(causing the clutch to start and stop spinning)?
- Does the fact that the clutch is only spinning part of the time mean that I should replace the belt? And if so, any special requirements other than releasing the tension on the belt, remove old one and repeat for installing the new one?
- Does the fact that the clutch is only spinngin part of the time mean that I should replace the clutch? And if so, how do I do that?
