I am sure this has been discussed somewhere and I wish I had the time to just search every post but I don't. Does anybody have any prior experience troubleshooting the pull-down motor on the trunk? We started out checking the fuse. We just replaced the part that plugs into the wiring harness. Still will not work. It goes up but will not pull down. Just installed a new motor and entire assembly gears, switch and all. Same thing. It will go up but will not pull down. Any suggestions?
