So you have a new alternator. I S IT CHARGING ? If the answer is yes , and the battery still dies, I would say there is a 12 volt drain in the electrical system. Hope this helps

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.

My 1988 Cadillac Deville has a new battery and alternator but still looses charge over night,Checked lights everywhere none are on at night??? why does it still discharge??

A 12V battery drain, doesn't necessarily mean a bulb is on. There could be 17,842 other reasons such as a sticking seat switch, blower motor staying on, I could go on. Need to have it tested for that,and identify the circuit with the drain on it. Then beginto search and see what is the cause. Hope this helps

Car won't stay running.

alternator does not hold a charge it simply charges the battery by unhooking the battery you are taking all voltage from computer and car will not run the proper way to test your alternator is use a multimeter and check voltage at battery while car is running if you have 13-14 volts it should be fine.
