Can you hear the motor humming like it's trying to run? Or completely quiet?
Any sound from motor with switch in Up or Down. There is a separate relay for up and down. Sorry, I dunno their designation or locations. Probably near the fuses.
2 fuses too. F51 for raise, F13 for lower. Huh, I didn't know that 'till just now.
I just fixed this problem recently myself with my convertible. Go on you tube and look up videos on how to fix the motor of your top. You will have to take apart your back seat to fix the problem. My fluid was out in my motor. I filled up the pump like the video said and now my car is as good ad new. Works perfectly. Thank God for you tube. Saved me some money.
