Blower motor won't blow on low or high
OK on my daughters 77 TA I've got a bit of a weird problem. The blower won't work on low or high. It's fine on the center 2 settings, but no go on hi or low. The car has a brand new wiring harness so I don't think it's a wiring problem. I bought a brand new hi blower relay thinking that would at least fix the hi speed. No difference. I installed a new switch on the control head itself and that didn't help either. Her car has some type of switch mechanism on top of the evaporator box that my 79 does not have. It makes a clicking sound when moving the control head so I guess it's doing what it is supposed to do. Any ideas?
