My car door won't open from the inside. I took my door panel off to check what was going on and everything is connected properly and nothing is loose. When I pull the handle, the rod extends but just doesn't extend far enough to pop the latch. I can manually pull the rod the the extra distance to pop the latch. Wondering if anyone knew if there was a way to tighten the rod or do I need a new rod, door handle, or latch assembly?
