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 terminal "C" to battery voltage and terminal "D" to ground. See Fig 1 . If continuity does not exist between terminals "A" and "B", replace relay.
