How to install blower motor relays??
I think I have it figured out, I'll put up some detailed diagrams of what I end up doing. To do it right, you need 4 relays, 3 for A/C mode, and 1 for heat/def mode. As it seems that when on heat/def mode, even high speed runs through 1 of the resistor coils via the 14BR wire instead of bypassing all of them in A/C mode via the 14T wire. In heat/def mode, there really is no way to not have the current run through the L-M-H switch.
High - Heat/Def mode
