thought it was the fuse. turned the wipers on with ice on the windshield. Stuck o Mundo! Fuse is good got power to the relay module. Put a new module in and still no go. I guess it's the switch or wiper motor, got no way to tell.
I'm putting a new motor in, the assist spring came off the spindle, and I don't know what position to put it in
The blower switch on the ECC stopped sending an electronic signal to the resistor relay unit which controls the speed of the blower fan. Bought a $15 all in one heater switch for some older truck, 4 positions; (OFF), (HIGH @10 amps), (MED @ 2.5 amps), and (LOW @ 2 amps) the resistors on the back got red hot, can't use it. A new ECC is between 1400 and 1600 bucks. Would an older buick blower and resistor assembly work if I affixed it some where and by-passed the diabolical and evil ECC. Presently I spliced into the cigarette lighter wiring and stuck a toggle on the dash to power the blower. Everything else on the sinister ECC works.
