Question about 1992 Cadillac DeVille
I would first reset the low refrigerant safety feature by disconnecting the battery for 3 or so minutes.
Then, I would charge the system with 2 or 3 cans of R134a if equipped with the quick connect low side port while the car is running and the a/c is on the lowest temperature setting (60 deg. F).
