Blower Motor: Description and Operation
Blower Motor Start-Up Control
This system consists of a coolant temperature controlled switch that keeps the blower motor from operating at coolant temperatures below 122 deg. F, an
in-car sensor switch which activates the system when vehicle interior temperature is high, and a DEF mode which allows normal operation of the blower.
