Q: Issue with my A/C, what is the most likely problem?
My trucks ac has worked flawlessly all summer this mornitwas the first real cold snap. I adjusted the temperature to warm this morning on the way to work this afternoon when I got back in the truck the air will do nothing but blow warm air. I have checked all fuses I have checked the fan and compressor they Both activate when the ac is turned on. I have no reason to believe I'm low on coolant it has always blown very cold. I suspect the temp control module has malfunctioned because there is no noticeable change in temperature when I turn it all the way to hot or cold. How do I test my theory
