My air conditioning does not work on low or medium--only on high. Any ideas what I should be checking or how to fix it?
More info---car is 1998 Chevy Prizm.
Blower motor resistor block. Get a new one.
That is what I was going to say.
RandomSD has hit the nail on its head.
This is a common problem with this design, and I hope the resistors are not too hard to access.
I like your handle, did you get it fixed yet so we know there is not a bad relay in the circuit (if it has one?)???
