Fix It and keep it

A problem with my 1995 Ford Taurus LX wagon caused the blower motor to operate at high speed with no way to slow it down. It just happened one day when i went to drive the car that the climate control fan ran out of control. The day before it had been fine so there was no warning when it decided to go haywire. The car has an electronic climate control system that regulates the fan speed electronically when you roll a wheel in the direction of either fast or slow.

I checked the climate control assembly by swapping it with another one that I had and there was no change. Checking further into the schematic I noticed that there was a variable blower control, (Ford part number: E9DZ-19E624-A), mounted in the ductwork to feed the temperature and motor speed back to the climate controller. Together they formed a feedback loop.

I removed the variable blower control from the ductwork and noticed that there was a damaged part of the circuit board rendering it inoperable. Since the variable blower control is a dealer item I had to order it from the dealer. I checked several aftermarket auto parts stores and none of them had a part like that so the dealer was the only option. It turned out that the dealer had one nearby at one of their other dealerships so I was able to have the part in a few hours. When I got it and put it in the blower worked fine. So it turned out to be a simple problem requiring a one hundred and twenty dollar part to fix.
