How to program the ac


It sounds like you have either a low pressure cutoff switch that is faulty or connection at the switch/wiring. The computer will only see the fault while it is operating and it will only set the code after 2 consective faults. Make sure you have the system checked by a professional to make sure pressures are correct in the system first.

Low-refrig ac off message is on


Does the AC system show normal pressure readings and maintains at least 28-32 PSI on the low side charging port?

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

On the dashboard of my 99 deville it says a/c off low refrigerant. how do I turn the ac back on to recharge ? thank you ...


You will need to recharge it to get it to come back on, it has a pressure switch that will prevent operation until the level is brought back up to normal.

My ac went out on my 98 cadi deville a few month ago. It just tells us low refridge. we tried to put some more in and the gage to fill it up says it is still full. but since then my econ/vent; heater; rear...


on those caddys you disconnect the battery and wait a few seconds and reconnect and it will reset ac system. when it goes into service mode the system just shuts down. the battery procedure is how to reset. when the ac compressor is not engaging you will not get an accurate reading on your gauges. it might be low but the compressor must be engaged for the system to take more freon.
