I had the same problem. The mechanic could not get the compressor to take in new freon. It has to do with the car's memory. You have to reset it by disconnecting the hot wire from the battery which for thirty seconds. This resets the cars internal memory, so it won't remember that it's out of freon. Reconnect it turn on the car and turn on the air the compressor will start.

Look online for the automatic hvac diagnostics , the diagnostics work through the a.c. control unit, you first have to clear the codes stored in the control unit before you can install more freon....

Hi! My 1999 Cadillac Deville for about 2 weeks started messaging low refrig-ac-off. Check engine light on!.


When you change your oil is up to you,you set the
months & miles you go. Any car with a reminder
for oil is just a gadget

You were told that your low on a/c refrigerant by the
message

Now the check light related or not has to be addressed,
by checking for codes & diagnosing the effected system

Your a/c system needs repair,not added to, only to leak out
& polute the atmosphere

Low ac refrig is on center console should i add freon or could it be a compressor problem.


You have a leak somewhere in the ac system. I'd add some freon for now, but you need to get the leak fixed eventually. Just go get a can of freon and follow the directions. It's really easy

Want to know what to do to get the compressor to turn to put refrigant in a/c on my 1998 cadillac deville.i know how to put it in ,but don't know to do to reboot the compressor.the dash says a/c off low...


you can locate the low limit switch and unplug it and use a wire to jump the terminals in the socket..that will start the compressor, car running of course, then add proper amt freon and plug switch back in
The switch should be on an ac line and have 2 wires

if it's like my 1997 Cadillac Deville, it has a bliue cap on the valve on the accumulator. This is a good spot to charge the a/c system with r134a.

Low rear suspension on my 1999 Cadillac DeVille


Do you hear your compressor running? It may be that it is getting tired and ready to burn out on you. I replaced the compressor twice on my Deville before I found that there were so many holes and nicks in the air bags and it was going to cost me almost $1500 to fix the whole system. I went online and found Strutmasters. I got a non air conversion kit for my car and love it. Saved me money and headache.

Why is my cadillac rear so low


You may have a leak in the rear air bags or the compressor for the air bags is not working,listen when you turn on the key to see if you can hear the compressor run ,if you do then likely the bags,if not then likely the compressor.

'96 cadillac deville has no air.cond./heat


Unfortunately for you ( i had the same problem) The A/C compressor HAS to be in working order on these cars or else all heck breaks out with the climate control.

If it's a nice car, get a new compressor installed. If it's borderline- get rid of the car.

I paid 2200 to Cadillac to fix the A/C and climate control only to have the transmission fail in my '93.

I dumped the car soon thereafter....

1999 Caddy Deville A/C problem


A/C systems are hard to diagnose without having access to the vehicle. One of the most common problems is undercharge (Not enough freon in the system) indicating a leak somewhere in the system. Other causes could be a burnt A/C compressor clutch fuse, defective compressor clutch, defective compressor/belt, defective High/Low pressure switches in the system, defective evaporator icing switch, defective wiring... Basically, you're better off getting the system diagnosed by a good A/C knowledgeable mechanic...
