Hi there. This my first Caddy and my first post. I hope you can steer me in the right direction. I have searched the forum and found no answers.

I have a 1988 Sedan deVille just purchased from the original owner with 94000 miles. The car runs like a swiss watch but has no AC. It is currently unplugged at the compressor to save fuses and the O/O was told that it will require a new compressor.
Here is what its doing. I plugged the wires back into the compressor, started the car, turned on the A/C and it cooled for 2 seconds then blew the 25amp fuse for the AC (the fuel display went dark as well).

Any suggestions?

 

He must have been told to replace the compressor for a reason. When you get a compresssor, rebuilt or new then you have to replace the ac***ulator and orfice tube as well. That's the only way that the warranty will apply and the system will be squeaky clean. Should cost no more than about $300-$400 if you do the work yourself, but you still have to take the car to an A/C place and get them to evacuate the A/C coolant. Then take it back after the work you do and they will recharge it.

 

Thanks for the reply. I am always suspect of surgeons and mechanics. I once had a "reputable" shop suggest that I needed to replace my rotted exhaust system on a car that,only the weekend before, had a custom stainless steel system installed.

This car apparently still has the original R12 refrigerant. I understand that converting to R134 is not a simple task.

Thought?

 

The changeover on mine was quite simple. If you are getting a compressor anyway it will be compatible with the R134 that's used now. You will also require about 6-8 ounces of oil in the system. Most of the compressors will have the option of being switched or unswitched also depending on what you have now.
