Where is a blow motor on a 1990 lumina?
up against the dash under the hood on the passenger side, to the right of the circuit breakers. Its black and rounded/cylindrical, but stubby you will see a wire with a plug coming out of one side of it probably the right side, or the underside.
I just replaced the starter motor on my 1990 4 cylinder engine Chevy Lumina. The starter is located in front of the oil pan. It was reachable and can be seen from under the front of the car a little to the right. You have to remove a three bolt attached plastic part by the oil pan to be able to get to one of the starter motor bolts. Good luck.
