Relay Test

Remove power window relay from underhood fuse/relay box. Using a DVOM, check for continuity between terminals No. 1 and 3. Check for no continuity between terminals No. 2 and 4. See Fig 1. Using jumper wires, connect terminals No. 1 and 3 to battery voltage and ground. If continuity does not exist between terminals No. 2 and 4, replace relay.
