Blazer Liftgate Pops Open
The liftgate frequently pops when shifting through reverse. This causes the interior lights to go on, and drains the battery within a few hours (if parked).
I started having problems last winter. I pulled the cover off the tailgate and lubed moving parts around the catch. Maybe I just need to spend more time doing this. This seems to fix it for a few weeks, than same problem all over again.
At this point I do not know if the problem is electrical or mechanical, although it seems to be mechanical.
I have used spray penetrating oil to try to clean the cable. Also used spray electrical contact cleaner as well as WD40.
I’m good at figuring things out, and following directions, but I’m no mechanic.
