SOURCE: 1996 cadillac sedan deville

have your plugs been changed,sounds like a wire may be crossed

SOURCE: 1996 cadillac deville lost instruments and died while driving

This is how I fixed it, I took the plastic cover off the fuse box under the hood and found a "maxi fuse" was out and replaced it. I was suprised that a fuse could kill all electrical on the car while driving it. How scary is that?

remove your license and behind it you will find i think two screws then remove that panel and you should be able to get to it.

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.

P0717 Input/Turbine Speed Sensor Circuit No Signal
The system uses a reluctor wheel and a magnetic sensor to aide in shift patterns. If the sensor wiring, sensor or wheel inside the transmission become damaged, it can trigger this code. This should be looked at by a trusted transmission tech in your area. Cadillac does some wierd thing things when it comes to placement, wiring and repiar. Get someone who knows Cadillac to get this done for you. It will save you a lot of heart ache and cursing at the car. Hopefully it will just be a bad sensor, and you will be back out on the road in just a afternoon. Let me know if you need anything else or wish to tackle it yourself. I think I can find some instructions.
