Window Motor
NOTE:
Window motor testing procedures not available at time of
publication. However, system is unchanged from 1990, (except
for some wire colors). The following 1990 testing information
may be useful in diagnosing vehicle.
With motor and drive assembly removed from vehicle, connect a fully charged battery to motor with an ammeter connected in series. Current draw from this no-load test should not exceed 5 amps at 12.8 volts, and should not fluctuate. Reverse battery connections. Motor should reverse rotation and current draw should remain the same. Motor must be replaced if current draw exceeds specifications.
