Auxiliary Blower Motor Control Module
WARNING: This page is about a different car, the 2007 Suzuki XL7. However, it is still accessible from the selected car via links, so may be relevant.
The following are auxiliary blower motor control module circuits:
- Rear blower motor speed control circuit - When the auxiliary blower switch is placed in any speed position this circuit is a pulse width modulated signal that is sent from the Auxiliary HVAC control module to the auxiliary blower motor control module.
- Ground - A constant body ground is supplied to the auxiliary blower motor control module.
- Low reference - This circuit is grounded through the auxiliary blower motor control module only when the auxiliary HVAC control module is in high speed. In all other blower speeds this circuit is a pulse width modulated signal (PWM). The longer this circuit is pulsed the ground the faster the blower speed will be.
- Blower speed feed back signal - This feedback circuit displays in percent on the TECH 2 the commanded output blower speed that the auxiliary blower motor control module is sending to the auxiliary blower motor.
