Heater motor. 1972 Lemans

[Johnnyj]

Finally got my car back from paint shop after almost waiting a year!! I'm starting to get the dash ready for installation.
The only wire I see coming from the duct area is blue.(I think that's for the air conditioner). Should the one I need for the heater be brown? How do I get
To the heater motor if I have to replace it!

you are doing a major project like this without an AIM or a factory service manual with wiring diagrams?
The 1971 factory service manual shows a 16 gauge black wire going to the blower motor.
the factory method to remove the blower is to cut a hole in the right side inner fender or you may gain access by removing it.

Or you can remove the inner wheel well, I have done it may times on 64-72 GM A-Body's
