Where is air conditioner relay switch on 1992 Buick Lasabre?

1992 Buick PA,if you add power directly to the clutch and it comes only obviuosly you have a power supply problem or low freon,Your system basically has a low pressure switch this is located on or near the filter drier,if you jump the switch together,you have low freon or a bad low pressure switch,

it could be your control unit also id check the fuse/relay otherwise blower motor i hope this helps please give me a good rating

its either a fault with the switch or the reostat

change blower motor you probably have something in there messing up the cylinder for the blower

The EGR valve may have a protective cover on it:


After removing the cover, the egr valve is beneath, you will need to remove retaining clips to remove the egr valve.

Check under the hood in the fuse/relay box there should be a relay for the headlights,have it tested its probably gone bad and needs replaced.

It should be in the relay center right above the blower motor.

It is located in the trunk under the carpet on the driver side

a few phillips head screws mostly around the door handle then just pop in plastic plugs
