I have a '70 that I recently acquired, and the defrost blower doesn't work. I need to pull it out and check it, but not sure where it is. I remember changing one on a '75 Trans Am back in the day, but it's not in the same place on the MC.

 

Your talking about the fan motor correct?

Its under the hood passenger side connected to the heatercore box....

heres a diagram...

thank you sir. will have to do some detective work tomorrow in the daylight; it appears mine has been removed and replaced with some sort of cover over the opening.
