2000 cadillac deville recharge ac how to

did you use the correct type of Freon for the compressor type?

Under the right dash. It should be the second one from the left, on the bottom.

might not need recharged. could be a bad high pressure switch. you will need a scan tool to test this.

you should have a shop evacuate system to see howmuch freon is in the system and pull a vacuum on it to make sure there are no leaks if no leaks if system was low they can recharge to proper level if u buy a recharge kit at parts store you risk blowing seals or hoses if you over charge

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.

Here's what you do.

Get an R134a recharge kit or R134a recharge hose (with an optional gauge) that has the adapters to put on to the low side port located near the firewall on the passenger side.

If the system is down already, the computer may have disabled the compressor.

To reenable the compressor, disconnect the battery for a few minutes and reconnect.

Charge the system with about 2 or 3 11 oz. or so cans of R134a while the car is running and the temperature is set to the lowest (say 60 deg. F).

If your recharge hose has a gauge on it, the right pressure should be in the green area ranging from 25 psi to 45 psi on the low side when the compressor is running.

Just get an R134a recharge kit, and follow the instructions.

The kit contains canisters of oil and R134a and a hose with a gauge on it.

Add about 2 or 3 cans of refrigerant on a system where the refrigerant leaked out.

One may also want to add leak sealer. which comes in a can like the pure 134a.

Alot of the time the cooling system will only work in Economy when your cooling system needs to be recharge. It does this to protect AC pump. Recharge and check for leaks. Should solve your problem.

Must be Air-Condition System Lines/ Hoses leaking R12 Freon (gas).

MAYBE THE PULLY HUB BEARINGS FAILED OR
DUE TO VERY LOW R12 FREON (GAS ) will not work.
Because there is a switch in the receiver/dryer prevent AC from working when low R12 Freon present, to protect the system & compressor damages.

You must fix the leaks, before recharging it.

They must **** the old (residue) gases from the system & lines / hoses...... & stay in the vacuum pump 30 minutes to proof no more leaks.

Recharge some oil for the old type R12 Freon gas.

Before recharge it to 62-67 psi R12 Freon
