can you tell me how to fix a problem with the blower motor changing position when the motor is under load. a/c works fine but jumps back and forth between a/c position and defrost when engine is under load. seems to be a dodge thing. i have two pickups that do the same thing. had vaccum lines checked (cursory) but nothing apparent. thanks

Hi there,

I would be checking the actuator vacuum system, get the system check with a hand vacuum pump, i feel that you will soon find a leak, also check the vacuum supply is sound.
