My 70 Charger has factory A/C. The A/C function seems to work as advertised. The blower works at all speeds.  But the blower fan doesn't work in the HEAT or DEFROST mode. Any ideas? :shruggy:

I found this 1969 diagram that explains the routing of power to the fan motor, pretty sure its the same for 70...my guess would be its that white plastic switch with the vacuum ports...

check out this link too...
