91 350sd blower problem.I have 6.5 volts at plug going to blower regulator in high,and about 1.5 volts at low.With blower motor unplugged from regulator but connected plug I am getting no voltage(at blower leads).
...Does this prove a failed regulator ?
...Blower works on bench with 12v applied, any help would be greatly appreciated, TIA Johnny

The blower regulator completes the ground! THE power comes from external strip fuse.

Thanks for the help,I was kinda hoping I might be able to do a continuity check on the regulator to prove it was indeed bad but I dont have a schematic,I feel pretty confident the regulator is bad however ,again thanks,Johnny
