I’m dealing with the annoying issue of flickering overhead lights, and it appears that it is related to the switch in the rear tailgate. Bumps in the road as well as banging on the upper tailgate cause it to flicker. I’ve tried adjusting contacts and catcher to try and get the latch to maybe hold better, but no luck to this point. Does this switch have issues like the doors and I just need to replace it, or is there something else I should be looking for? Any suggestions are definitely appreciated. Thanks.
