I had a similar problem with the dash light fuse blowing on my 93 Lumina APV. Had it back to the Chevy dealer several times but they were not able to, or didn't want to take the time to look for the problem. I finally took maters into my own hands and took out the cowling around the instrument display.I found the problem was in the wiring bundle that was against the steering column. The insulation was worn where the wires made contact with the steering column. A little electricians tape and a piece of cardboard fixed the problem. No trouble now for 5 years.
The relay is sticking or the horn button on the steering wheel is going bad. Most likely it is the horn button.
probally wired the pump wrong
first thing I'd check is THE TAILIGHT fuse--if it blows, no tailights AND no dash lights. Good luck
Maybe a bad valve
Maybe a stuck thermostat, or a broken radiator/heater hose. Sometimes the radiator itself blows a seam. Water pump seal, blown head gasket, etc.
Should be the same circuit as parking/tailights Check all sockets for short to ground or overload Remove all bulbs and replace one at a time until fuse blows that will give an sidea where to further investigate
You have a bad fan clutch..............
There's duct work in or under the dash. Check to see if some of this duct work came apart.
the system is probably out of coolant.
check your PCV Valve
my chevy blazer 1984 the air conditioner blows from down side only.
Yeah, Cavaliers are a good car to start off with!
