This is the 2nd spring that I have had this particular problem. Last spring, I noticed my A/C would cut entirely on highway driving. Sometimes it would come right back on if I toggled the switch off then on, but sometimes the remainder of the trip would be hot. Then the problem completely fixed itself, worked normal up through November. This spring, same problem. It works fine in stop and go traffic, even for hours, but will occasionally cut out. Any ideas? Today was around 70 degrees F, and it cycled only every 40-50 seconds or so.
