You need to replace the blower, cut out a section from the hood side then replace it with a new one and place insulation layer glued to the casing

if it was replaced them most likely the terminals in the connecer ar sloppy and need to be tightened unplug the blower connecter and look at the terminals a small pick is udes to prise the trems up and tighten them

Check the ground wire behind the alternator.

A 1998 Cadillac Deville does not have a blower relay. The system has a fuse and a controller to feed power to the blower motor.

The blower motor relay on a 1980 Cadillac Coupe Deville is situated on the passenger side. It is located in the vicinity of the firewall and is just below the windshield.

Probably the blower motor, wiring to it or control switch

The blower motors only work with the engine running. If the blower motor has three wires on the electrical plug, then the blower motor module is built into the unit & it's very expensive. Sometimes, you can tap on the motor with a hammer & it may work or slowly turn. If this is the case, replace the blower motor.

Assuming that the a/c was in good shape before it suddenly stopped working, the problem is probably the blower motor. As it turns out, this is very common. Try searching answered questions under "blower motor 1997 Cadillac Deville" I just had to change mine in a 1996 Deville. Motor aprox. $240.00/Labor aprox. $100.

Open hood . Disconnect blower module located near blower fan. Disconnect, if blower shuts off, repalce module

The blower motor fuse protects the blower motor electrical circuit. The blower motor relay operates only the high speed function of the blower motor. The blower motor speed resistor operates the lower speed functions of the blower motor.

under hood center of firewall / on my DHS it's under the dashboard on the passenger's side.

Right side under dashboard. Remove plastic cover then look for a Round plastic cover.

I recently had mine replaced on a 1996 Deville. The motor was $238.00 and labor was $97.00 ($335.00 + tx). I went to a local a/c shop 1st and was quoted $500.00 for the same thing. It pays to shop around.

It appears your blower motor is not working correctly on your 1980 Cadillac Coupe Deville. The vents are for both AC and heat. You may also be losing vacuum pressure. If you cannot find the source, your mechanic can help you do so.

just a guess because im not positive but may be in center of firewall. that's where they are on 95 and newer. you can do it yourself but its hard to get at.
