intermittent heater blower problem
Hi
I have a heater blower problem on my 1997 Aerostar~the blower does not operate at times. The motor test ok and the fuse is good. If I remove the fuse and put it back, the blower will operate for a while until I hit a bump in the road then it will cut out, hit another bump sometimes it will start up again. It's the same thing if I bang the dash, or wiring under the hood. It's an intermittent problem, but where to start checking?
It's -30c to -35c up here these days so the fan switch gets a good workout.
