The two lowest setting of four settings do not work. How to trouble shoot the switch setting or motor itself?
Your posting does not include what settings on what you are referring to
Look at the blower resistor block. That's what control the speed. It is generally located next to the motor. Look for electrical wires connected to it.
I am surprise your valve covers aren't leaking.
You have two other places to look at.
Look at the oil pressure switch. Sometimes it will leak.
Look at the rear oil seal on the engine. This of course can not be seen, since it is between the engine and transmission. But will will leak after awhile.

Thank You
I'm trying to pinpoint a leak of oil from under the engine. I've put a piece of cardboard on the garage floor, placed it just forward of the front axel line to help locate its origin. Due to minimal ground clearence, I am unable to crawl underneath to witness as it drips. Losing about 1 quart of oil every two months, and it does not burn oil. I've cleaned off the visible road grime and checked the dip stick connection bolt, oil pan plug, head gasket bolts, and all are tight. With the age and mileage of this 4cyl '01 Cavalier, is there an oil additive to assist in locating this leak ?
