"You" wouldn't fix it. You would replace the compressor with another & give up the defective one as a core for rebuilding. This is what I am doing now in my 1995 ditto the rest.
I have a 1993 Chevy lumina van that has heat but doesn't have a fan how do I fix the fan?
Take it to the garage.
replace spark plugs and wires
If your lucky, get one from junkyard or from a cheap parts car.
Go to the parts store and ask for a new one.
CHECK YOUR FUSE
1999 Chevy lumina, won't start, security light comes on ,can jump the starter but motor will only run for a short time , strong battery ? tried different keys , no good ? help
take apart the dash, and reset it to park when the car is in park.
spend money,replace the compressor.sorry...
You could, but it would probably be a bit more effective just to fix it the right way.
possibly low on freeon. ** Fairly cheap fix from the local auto parts store.
