I TURNED THE BLOWER CONTROL ON HIGH AND IT SOUNDED REALLY FAST FOR ABOUT 15 SECONDS BEFORE IT QUIT. FUSE IN FUSE BOX IS OK. THIS IS IN 69 BIRD WITH A/C. JUST REPLACED BATTERY CABLES AND WIRE AND NEW FUSE BLOCK AT BACK OF ALTERNATOR. IS THERE ANOTHER FUSE SOMEWHERE ELSE OFOR BLOWER AND WHERE IS BLOWER MOTOR LOCATED?
There should be two or three resistors on the top of the blower case, inside the passenger compartment, behind the glove compartment. You probably fried one of them.
D'Oh ... that might be on my GTO ... not on the Bird. Sorry about that. I'll look at mine tonight and see if I can help you a little better than that. Sorry for the screw up. I'll let you know tomorrow!
