Well- about 15 years ago, I had water into the passenger well, and it was the drain hole clogged under the windshield plastic dam with debris ; The car does sit outside, and about 5 yrs ago I had prophylactically removed the wipers, sub-windshield plastic dam, and cleaned things out. I need to do it again, but try to keep debris out of the grille area above the 'dam', on a daily basis... The blower area now is dry, and so's the cabin, so I suspect the resistor is ok; easy enough to change it out at this point, I still have everything out for my aborted vacuum element repair.... I will try the new trimmer/potentiometer . Is there a writeup anywhere on removing the vertical PCB that the pot is soldered to? Ive seen some talk of removing the thermostat wheels on either side, and the hex-keyed white plastic struts that they attach thru to their pots. There appear to be a dozen small plastic tabs that lock the PCB in place, and the front control ***** of course need to be pressed off the front of the board. I just hope I can figure it out without damaging anything.
Thanks again for the feedback and information- mrw
