Window Relay

With one test lamp lead connected to relay output side and ignition in "ON" or "ACC" position, test lamp should light. If lamp does not light, check continuity of wiring harness from ignition switch to actuating terminal on relay. Check voltage at input terminal. If wiring and voltage are good, replace relay.
