Air ride
I have a 85 buick riviera and the air ride is sagging
in the back. I tested the pump under the hood and
hooked to 12 volts and it works. When i bought the
car the owner said he unpluged it because he
thought the level sensor was bad. I plugged it in
and nothing happened. My back end rubbs my
tires. Is there a way to either fix it or at least raise it
up?
