Current Draw Test

BLOWER MOTOR CURRENT DRAW TEST
This current draw test will determine if the A/C blower motor is operating properly.






1. Connect a 0.0-30.0 ampere ammeter, ground the negative lead of the A/C blower motor and measure the heater blower motor current draw at the high-speed setting.
2. If the A/C blower motor is operating properly the current draw readings will be within 20.0-25.0 Amps.
