without more information, check the following:

Make sure there's plenty of coolant in the Radiator / Coolant reservoir.

Does the engine warm up to proper operating temperature? If not this would indicate an engine thermostat that's stuck open.

Does the blower motor come on when you turn the heater or air conditioner blower on?

See if the AC fan at the front of the car comes on when the AC is turned on/ It needs the extra air flow.

1. Check the air conditioner fuse and replace as necessary.
2. Air conditioner system discharged. Have the system evacuated, charged and leak tested by an MVAC certified technician, utilizing approved recovery/recycling equipment. Repair as necessary.
3. Air conditioner low pressure switch defective. Replace switch.
4. Air conditioner fan resistor pack defective. Replace resistor pack.
5. Loose connection, broken wiring or defective air conditioner relay in air conditioning electrical circuit. Repair wiring or replace relay as necessary.

You have to see if the fan works, see the thermostat, check if you have no drain coolant.Nota You should vary the thermostatato.Gracias good luck and I hope your comment ...

hole in radiator. water pump leaking. leaking coolant into cylinder head from bad gasket. bad radiator cap can cause it to loose coolant . also check the hose to overflow resivore.coolant could be boiling away due to overheating. check the thermastat and the fans. all fuses and relays.as far as the codes check the wiring. if u have to unplug all the connectors and remove the loom and visualy inspect the wiring harness. i had to do this on my 93 deville. i found the reason my ac wasnt working my cruse control . and throttle position sensor. my temp sending unit was seting the idiot light . and the alternator was seting the charge light. all becase of a bad spot in the wiring. i seperated the wiring and tapped each individual wire up. re loomed it and taped over the loom . now my car runs and drives as if i drove it off the show room floor.amazing what a few hours of checking and repairing a few wires willl do. the cadillac dealer ship estimated around $2,000 to fix my problems depending on hours involved at $100 an hr. it cost me 2 rolls of electrical tape and $10 in loom. and like i said a few hours.

check fuses

on my 99 devillle concours cold air blows from left and back vents but hot air blows from right vents

check the compressor with the ac running and make sure the compressor is kicking in and out in not the compressor might be bad or te clutch on te front of te compressor, sometimes u can get to much freon in them to i did it ounce

the problem could be the engine coolant tempature sensor. all1992 through 1994 models equipped with electronic climate control can display trouble codes.replace coolant temp sensor.if problem contines have powertrain control module checked
