My 2002 Ford Explorer developed a weak defrost late in the winter (I don't drive it all that much) and now in summer the air conditioning has a very weak air flow -- doesn't cool anything. I'm sure it's in the blower (last oil change guy said as much) but I'm afraid a dealer/service person will charge me an arm and a leg to do something radical. Just around 115,000 miles; no other mechanical issues ever.
I'd like an idea of what exactly would have to be done if it's just a blower issue. A dealer currently has the vehicle and will come back to me tomorrow with some kind of diagnosis/estimate. Can an independent mechanic work with blowers? How do I know any estimate will not be ripping me off?
