Question
JDC2500HD
First off let me say how great this site is. Now for my issue. A/C started intermittently blowing warm air on occasion. Air starts out ice cold then goes warm. Might be 5 miles might be 20. Took the truck to a local shop and they told me that the system was low on freon. So they evacuated the system then recharged and added dye to check for leaks. Told me it might last all summer or a couple of weeks. This was on a Saturday. On the following Wednesday same issue, Took truck back to the shop following Saturday. The issue happened at the shop so the mechanic saw what it was doing. He ran some diagnostics and this is what he came up with. Power at the a/c clutch but would not cycle, scan tool shows switch off when it is on on the dash, I believe the high and low pressures were within range. Told me I need a new compressor and it would cost a $1000.00 to fix. My question, is it the compressor or the clutch? Again, it starts out cold then goes warm and may not go cold again for some time even after the truck has been run and shut off several times.
Thanks in advance for any advice. Jeff
