I am so sick of this crap. I knew one gear was gone. Replaced both with brass. That was2 months ago. So now the other day onl 1 would go up. Flicked the headlight switch a few times and both poped up. Now yesterday only 1 wil go up? So pulled the connectors at the harness and tried cleaning the connectors and they both worked for a few hrs. Then neither one worked. Did it again and both worked for a few more hrs. Now only 1 again Any ideas? Module or headlight switch maybe?
