I have a 1996 Explorer. The A/C only comes up when the fan speed is on its highest. It's not doing anything at the other speeds. Would that be a belt problem?
Could you rephrase the question?
Are you talking about the blower motor inside the car?
Yes; when we're sitting in the car, and turn on both the A/C and fan speed controls, no cool air (or any air for that matter) comes out unless the fan speed control is on its highest.
OK, then you are simply referring to a problem in the blower resistor circuit. (Resistor assembly, wiring, or control head)
Is it easily fixable by a mechanic? We can bring it in when it's scheduled for inspection. Not a great rush now.
Yes. The hardest part will be access to whatever component has failed, and for an experienced person, that's not a big deal at all.
