I just got my AC working again (with new compressor, dryer, expansion valve, AC thermostat). After returning from the shop, I notice that the cooling fan is always running, even at start up early in the morning. I also notice that the temp gage rise steadily after 20 minutes of normal freeway driving (no up hills). It heats up an extra 30% from average. As soon as AC is turned off, I can see that the temp gauge drops down to where it's suppose to be. Are these two problems related or what can I check to diagnosis the issue?
