I spent a year and a half and $$$$. At dealers trying to determine why my top would not go up or down! By pure luck the owner of Top hydraulics, Klaus Witte, asked me to check the two travel sensors on the left main lift cylinder to see if they had inadvertently been switched around when someone replaced the cylinder.
sure enough, that was the problem! Now my top works perfectly! I find that Klaus and pizzaguy are the two best experts on the crossfire!
