On my 93 Loyale SW, 5 spd, 4WD, 225,000 miles, the blower motor, after running for months only on the highest setting, finally quit. The Haynes manual and the internet suggested the blower motor resistor was the problem, so I located and removed it and found its wire coils in shambles. Got a new one and installed it and still no blower operation at any speed.
I pulled the blower and tried testing it with a wire from the battery pos terminal to one of the terminals on the motor and grounding the motor housing to the battery neg teminal. (Pardon my ignorance, but is that one way to test the motor? The Haynes manual says use a jumper to the blue wire at the motor when it is in the car, but I had the blower out to check for mouse debris).
Meanwhile, another possible culprit is the blower motor relay (according to Haynes and the internet) which I cannot find to save my life! (Red/Yel, Red/Wht, Blu/Red, Grn/Wht wires to it, per the Haynes schematic.) Where is that located?
Finally, I have not posted much to USMB and am wondering if one can search archives somehow. I cannot figure that out either, sadly.
I have checked the fuzes and they are ok, and actually got a heater/defroster/AC control assembly and 4-speed blower switch today from the salvage yard but before putting them in, I want to make sure the motor functions.
1) How does on test the blower motor out of the car?
2) Where the %***&% is the blower motor relay located?
3) Is there an archives search feature for the older Subs?
Any help greatly appreciated. I am the original owner of this car and cannot let it go, rust and idiosyncracies and all. I have put in new radiators and front CV axles, replaced the timing belts, and done homemade "bodywork" on the car for twenty years but this one has me stumped. Got to get another 250 K out of it. (:
