My passenger seat is very difficult to tilt forward. The release feels fine, but need 2 hands to push it up. I was away for 2 months, and it was fine last time I used it which was a little before I left. When I got back, batteries were dead and this. Any clue what could be causing this? Is there a spot that maybe needs to be lubricated? It was extremely wet while I was gone (probably wettest Aug & Sept on record), not sure if that may have done something. Car was under a cover, but outside. Any thoughts would be appreciated.
