Re: popping sound when i put on A/c, losing power too!

Look at the A/C clutch when the A/C is turned on....is the noise coming from the clutch or compressor? May have a bad compressor that is putting a load on your vehicle......remove the belt, and grab the clutch(not the pulley), and see if you can easily rotate it.....

Remember this can happen when you turn the the mode switch to defrost, because the A/C will engage in this mode...

Does the engine run rough/stall, ONLY when the A/C clutch is engaged? Or do you also feel this when going up hills under a load?
