 blower motor problem on 99 contour
Having problems with a 99 ford contour blower motor. At first blower only worked on high, couple weeks later didn't work at all. Checked resistor and it was bad and replaced. Worked fine for a couple of weeks and then quit again. As I was going threw the system checking for power unpluged relay and plugged back in and the blower works fine again. Now during this whole process the lights(interior and exterior) have stated pulsing all the time. Any hints on what direction to go next?? |
