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

See the web site like www.youtube.com/video site to see How they service & repair air-condition system?

The gas tank door wont open for my 1994 Cadillac deville

Sounds like the door release actuator is sticking. Try lubricating the latch when the door is open. In addition to using the button on the dash, you should be able to open the door pulling the wire adjacent to the fuel door inside the trunk.
