Cadillac Repair Questions? Ask a Mechanic for Answers ASAP
Your vehicles ac system is computer controlled & when it blows cold on one side & hot on the other it is usually a failed temperature actuator motor for the side that blows hot.Since your problem is now hot on both sides ,I suggest you have the system checked for the correct amount of freon.If there is a low freon code in the computer memory this will need to be cleared after charging the system for the computer to turn on the compressor.
Its blowing hot now on both sides now but i got a gauge meter to read how much freon is in it and its reading full
