Are you looking for the heated glass element relay?
Ok. If the switch on the dash operates it, I wouldn't think the relay would be the problem. I would be leaning more toward the switch on the tailgate. He has determined that the switch on the tailgate is functional?
Alright, so needless to say, all ground connections have been checked and no bad connections were found? If it were a relay I don't think either switch would work. I would suspect a bad switch or ground connection if directly grounding the motor operates it.
