One of the wires could be exposed and shorting out possibly which is in result not giving anything power, maybe the ecu/ecm is bad or something internal with the computer which isnt getting power or recognizing it

Automatic ?? You should be able to unlock the doors from the inside and open them. If someone set the child safety locks you may have to remove the door panels and unlock from the inside of the doors.

Check the connections at the battery for shiny and clean appearance when disconnected from the battery.

Charge the battery and replace if necessary as determined by a load test at your local Walmart, Sears, or auto parts store.

I had some dirty terminals on my 1997 Cadillac Deville Limousine that caused a no start condition just the other day.

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.
