Question about 1990 Chevrolet Cavalier
When I turned the air conditioner on the fuse under the dash blows. I have changed out the blower motor. That is not the problem. When I have the heater switch on, then turn the key on the fuse does not blow. Could it be the relay?
There is a loose ground and or wrong size fuses for the air
if loose ground you will want to have a certified mechanic trace the grounds back to source
i dont think it could be relay but there is a way to check this
find the relay panel in the engine compartment open it
find the relay that says air conditioning
pull it out
now there are numbers on that relay
in that same relay box theres relays about 6 to 8 of them that look similar to the air conditioning relay
this is where the numbers come in if the numbers match switch with other relays
mark the air conditioning relay with black marker or nail polish so you know which relay is which
if its the relay thats bad the new relay from the relay box put in its place will work fine
put the old one back in the slot where you took out the other relay out of and then proceed to dealer to purchase new relay for your vehicle if the relay was the problem

verify that there is power to the blower motor and that a fuse is just not blown.
if the fuse is good and there is power to the motor you will need to replace the blower motor.
