Hello, I drive a 1999 Ford Crown Victoria LX with 146,550 miles. Ive been having a weird AC problem. There are times where the AC will blow cold and the heater will blow fine, and then randomly one of the two will stop going. The AC will blow cold and the heater won't blow hot or vice versa. To do a temporary fix, I disconnect the battery and let the computer reset and it fixes it for a while, but im becoming tired of doing that. Ive checked and replaced all fuses, brand new alternator/battery, new coolant, and I even recharged the ac system. However, still no go. The AC will continue to stay stuck on one of the two. Is there anything else I can do besides disconnecting the batter to fix it? Maybe change a circuit breaker? Thank you from California!
Well you have an electronic problem. It's easily could be a bad body control module to computer module n**** bad. You'll get weird crap like that. For my experience it's either bed module or a bad control unit , the part that you turn with your hand those will go bad. Do the same thing
