Power Window Relay Test
Remove power window relay from underhood fuse/relay block. Using DVOM, check for continuity between relay terminals No. 1 and 2. See Fig 1 -Fig 2 . Continuity should not exist. Using jumper wires, connect terminals No. 3 and 4 to battery voltage and ground. Continuity should now exist between terminals No. 1 and 2. If continuity is not as specified, replace relay.
