Levi, If you have the same climate control, then below is a link to a repair video for your climate control. Sorry, this is the part 3 video, look a the side to find the part 2 video and watch it first.
If the a/c does not engage as a result of the electronic control system in your 1996 Cadillac, the climate control system may need to be replaced.
However, if the problem is being caused by low charge of R134a in the system, have the system charged before changing that electronic part.
I have never seen a Cadillac Climate Control System do this, which leads me to believe that it may be more electronic than refrigerant pressure related.
If the refrigerant pressure was low in the system, the climate control system should still stay on 'auto' mode, I think, and simply blow warm air.
IT MEANS THAT A FAULT HAS OCCURED IN THE SYSTEM AND THE SYSTEM HAS BEEN DISABLED, TO FIND THE FAULT YOU MUST HAVE THE DEALER TEST IT FOR THE TROUBLE CODE THAT IS STORED WHEN THE LIGHT STAYS ON.
the problem could be the engine coolant tempature sensor. all1992 through 1994 models equipped with electronic climate control can display trouble codes.replace coolant temp sensor.if problem contines have powertrain control module checked
One of the sensors at the wheels are not working right. Located on the backside of the spindle look for a wire running to a black plastic sensor. It's possible it might have a crack in it or they are just getting old. ABS- for panic stops if light is on you will have normal brakes. Traction control- for wheel spinning out or burn outs slows motor down so wheels get traction if light is on next time you stab the gas you will have a nice burn out. (Normal driver)
