Hi, another question for all the experts out here. My sunroof/moon roof will only tilt open, not slide open. I was wondering if it works off of two different motors or if something is just messed up? I saw someone mention something can get out of sync that's why it has only one function. It seems like everything is connected. I would really like to get it open so I can clear up the drains, been having to cover it with a tarp so I don't get that tasty mildew smell.
