the heater motor wont stay runnig at any speed, each time it quits like in a day or two the only thing that gets it to run again is to move the line to the motor at the base of the fuse/relay area and not at the motor connect like I thought it would, motor direct to batt checks good, purple wire from motor to high speed relay good but dont know if relay is faulty?black wire good to the firewall harness,after removing fuse/relay unit from firewall saw no burnt wires, cleaned all plug connects, I havent found anyone with this problem thru internet yet.
