My blower moter won't turn off when I turns off my 93 cadillac seville it continues to run what could be the problem
One of the 4 very common problems. One of 2 things wrong depending on design. In the 80's they had a resistor module under the hood on the passenger side. If there is no module, the problem is in the BCM (computer). I don't remember the year they changed.
Answer is to rewire blower motor which is simple, but you will only have high and off. If this is acceptable let me know and I will give instructions. VERY VERY common problem since 1982!
