Hi,

Try to reset the computer.Just disconnect the battery power for 8 seconds, this will reset the computer, then reconnect the battery this should get the message to erase and your AC should work.

If problem persists, check the pressure sensor ( Usually located in the high side line ).It might be due to fault pressure sensor.

If still, it would not solve, get back to me.

Hope i helped you.

DO RATE THE SOLUTION.

Thanks for using 'Fixya'.

You may have a bad dash control switch for the air-conditioner or a relay that is not functioning properly.
Your problem is most likely the controller system. I would suggest you to contact an aircon tech, this is a job for an expert because of the injuries that could result when the job is done wrong.

Have a great day!

1993 Eldorado Cadillac ac compressor won't take freon. Display says compressor off, low refrigerant. How to bypass computer? Can compressor relay be jumped using paper clip? Which holes? to


Grab some refrigerant gauges and take readings. If the low side has more than 40 psi or so of pressure, the low limit switch will close and allow the compressor to run. If there is indeed low pressure causing the compressor not to run, you will need to flush the system after eliminating the source of the leak. If the a/c compressor has never been changed, it is probably the source of the leak.

I have 1988 cadillac allante the lh rear brake line rusted through know the brakes wont bleed no mater what i do even tried staring at abs pump and master evev replace some calipers


You may need to go to the master cylinder and release the piston for the rear brakes circuit. It is best to get a manual for this operation as it may require the removal of a switch in the master cylinder or a threaded pin between the pistons. There are two pistons that are spring actuated and when one circuit loose pressure a piston is stuck in the wrong position.

93 Allante AC Compressor won't come on to recharge system


On most models you would need to jumper the low pressure switch while you are recharging the system. There should be a low pressure switch on the low side line and a high pressure switch on the high side or on the compressor.

Recharged a/c do u have to clear ecm or bcm what is the codes


You do not have to clear either module. If the AC still doesn't work then there is still a problem like an AC compressor clutch or compressor cycling switch in the low pressure refrigerant side line..

Where is the ecu for the 1987 allante?


It is behind the right side of the instrument panel.

With that said, it deserves mention that your 1987 Cadillac Allante is capable of self-diagnostics and system status/fault code display through the Instrument Panel Cluster (IPC) and the Climate Control Driver Information Center (CCDIC) panel display. It is like a professional scan tool built right into the car.

For information on how to use this feature and complete diagnostic instructions, I recommend that you subscribe to alldatadiy.com. The pricing is extremely reasonable, and all the technical/repair information you will ever need for your Cadillac can be found there. (It is the same information that I would use if you brought your vehicle to me for repair.)

Air compressor on 1988 cadillac deville will not turn on. Have installed new electronic control module and we think that has gone bad. Cannot locate a new one? Any suggestions


2 fuses under hood fuse box. makes sure there good. under the back seat there is a fuse and a relay. The fuse box cover will tell you where they are. If all fuses are good and the relay is good. Then you will need the control module located behind the trunk cover lining on the right side or the air pump located under the car next to the right rear wheel. My bet is on the air pump...

AC runs for a few miles,then says it's low on freon and the compressor kicks off. It is not low on freon and I had a mechanic working on it for months. New compressor, dryer, orface tube, etc. Can you...


What is the pressure when the compressor running? should be between 25-35 PSI no more then that cause it wont get cold and might even say low on freon.
