Blower Motor Keeps Running

I have a 98 Sable and the A/C - Heater fan will not shut off. I have un-pluged switches and it still runs. I also understand that there is a blower relay in this car, can this be the cause? I have checked to make sure ing. is turned offf and it is. No other problems except for the blower.

Hi, Either the relay is stuck OR you have an electrical problem which in MOST cases is a bad ground in the circuit., Get yourself a ford shop manual and electrical diagrams for the circuit and follow the flowcharts to the letter for BEST results at diagnosis, GOOD LUCK,........, Clay..
