Power Window Relay Test

Remove power window relay from underhood fuse/relay box. Check for continuity between terminals "A" and "B". Continuity should not exist. Using jumper wires, connect terminals "C" and "D" to battery voltage and ground. See Fig 1. If continuity does not exist between terminals "A" and "B", replace relay.
