I have a 2004 C70. The air conditioner will run for about 15 minutes, very cold, then the compressor shuts down. I have given it as much as 5 minutes to cycle back on, but it never does. All I have to do is turn the compressor switch off for about 1 minute, then turn it back on, and the compressor will run for about another 5 minutes and I have to cycle it again. What needs changing? I presume it is some sort of switch, but there are so many. Which are the most likely ones?

 

thats an easy fix and work on ALL cars/trucks. Remove the front bolt on the compressor, slide the clutch assembly off the front, inside the center shaft you will find two washers, remove the smaller of the two. Reassemble the clutch onto the compressor and thats it.

The "gap" in the clutch has gotten to big and when it gets hot it quits working. They tell you to replace the clutch, but look at what one costs. I have done this fix on a 97 Expedition, 99 Explorer, 99 Grand Am, 96 325i, and 850 T5... worked on all!!
