Power MOSFET

POWER MOSFET

INSPECTION
1. Ignition "ON"
2. Manually operate the control switch and measure the voltage of blower motor between pin 1 and 2.

Specification:

3. Select the control switch to raise voltage until high speed.
4. If the measured voltage is not specification, substitute with a known-good power mosfet and check for proper operation.
5. If the problem is corrected, replace the power mosfet.
