Hi Guys, I need a new resistor for the blower motor on my '68 GS. It is a 3 speed fan with A/C. The unit I believe is the 490000 automatic climate control (or some name close to this). Anyway, there are 4 connector blades and 3 resistor coils. OPG says I can't get a new part, I am desparate! Any help would be greatly appreciated. Here are pics: Michael G
