I've got a 2007 Navigator and the A/C works great when the truck is first started, but once you start moving, it shuts off within a couple of miles. We thought it was stopping when the truck got up to temp, but when sitting still in the mechanic's lot, it ran fine and blew cold for over an hour. But as soon as they took it out onto the road, the compressor cut off in a mile or two and wouldn't come back on until it completely cooled off.
It's not a blend door issue or blower issue, all that still works fine, it's just the compressor kicking out and staying out. There are no codes from the EEC or from the climate control module either.
Just an FYI, we had the whole system repaired last August with new compressor, evaporator, dryer, etc. They also just checked the freon level and it was a tad low, but not much. They did top it up and made no change.
Any ideas of what to look for? The mechanic (not a dealer) is stumped.
Thanks!
