Power Windows do not Operate at All: Wiring Diagram

1. Remove the fuses from the instrument panel J/B.
2. Check the resistance.

   Standard resistance: Below 1 Ω 

NG: REPLACE FUSE 

OK: Go to next step. 

1. Remove the relay from the instrument panel J/B.
2. Check the resistance of the relay.

   Standard resistance
