Question on fan blower and aftermarket AC relationship on a '73
My fan blower does not work. The car had dealer installed AC but the lower dash hardware was removed prior to my acquiring it and replaced with a non AC lower dash. I know the AC was dealer or aftermarket installed because I removed the rest of the hardware and it was pretty obviously a typical crude job with US parts.
Anyway to the question. In trying to troubleshoot my problem (I'm a complete novice on auto electrics) I noticed when looking under the dash at the backside of the slider mechanism and it's connections that there is a yellow/red wire coming from a metal plate which is part of the slider mechanism. The yellow/red wire eventually meets up with a black wire and both are joined in the back of a female connector on the other end. The connector is just hanging there without it's mating half anywhere around. In other words two wires in the back of the connector but no mating half on the other end. Also, right next to that connector is another female connector with a blue wire that is also just hanging there. Both have no place to connect to any longer. So the question is does anyone know if the blower system was integrated into the aftermarket AC and now that it has been removed my blower circuit is just open? Does anyone have any idea where to proceed next???? Thanks

The A/C system should have been totally self contained. It would not connect with your dash heat/vent panel.

Flintstone is correct. I had the same aftermarket set up on my 73 and there is no integration with the factory cool air system. If your blower doesn't work, try the electrical diagrams on this site--there is one for the 73--and see if the wires you describe can be traced.
http://www.pelicanparts.com/911/911_Parts/911_electrical_diagrams.htm It looks like the wires you describe are for the optional webasto heater that your car does not have, thus the wires end without a connection, ditto with the blue wire. Sounds like some other problem with the fan motor itself--could be seized or blown fuse (#7, I think).
