SOURCE: Electrical Problem with 90' Cadillac Sedan Deville

the climate control is intergrated through the pcm and ecm i would advise you to take the vehicle to the service shop they have a diagnostic scanner that will access the ecm and either clear a code that prevents the climate control from working or find a more severe problem that requires you to replace the hole unit. please rate this solution. thank you and good luck.

SOURCE: Fuel Data Center and Electronic Climate Control not funtioning

This is defenetly the BCM, I had a 1990 with all of the same problems. Buy a rebuilt and install it behind the clove box. Remember that you must install you memory prom into the new unit as they don't come with any in them (it is what is memorizing your miles driven.) You will get off pretty easy on this one as they are available and not too expensive.

How do i turn on my climate control


Climate control is turned on by pressing the 'auto/econ' button.
There will be a temperature control for it that lights up on the right hand side of console display. One can also control the fan speed there or leave it on 'auto'

I have a 1996 Cadillac Sedan DeVille. This spring...


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.

89 cadillac deville - both climate control and fuel centers are blank. Fuses are ok. any ideas


Those service windows are lit by tiny halogen lamps. Unfortunately, they can be a bear to get at. You will need to remove the front of the dash to gain access to the lamps. If you decide to do the job, do yourself a favor and replace ALL of the lamps while you have the dash apart.
