I have a 72 Corvette and have had the A/C reapired but the blower motor does not blow good at all.
My mechanic has looked it over and said there is nothing he can do.
Does anyone know of a fix for this?

 

First off tell "Your Mechanic" to "Forget about it". What do you mean the a/c doesnt work? Does the switch go Off-Low-Med-High? Check fuse box, If no high check the fuse in the engine compartment, on the left fender. When was the last time it worked properly? Check fan belt? Vacuum switch? Vacuum cans and hoses? Carpet hot got insulation? Transmition cover? Leaking window rubber? Does the a/c compressor go on? Got freon? Is the heater control valve stuck open? Hope this helps.
