Morning all, my mate has recently acquired a 94/95 byzanz cabriolet and has a queerie regarding the electric roof operation.
When purchased, the rear deck lift ram had been removed thus the lid had to be lifted manually.
He has bought a damaged donor car for leather trim upgrade etc which also has electric roof so decided it may be prudent to swap the deck lift rams between the car.
The operation is now good but when the rear deck lifts it gets to almost full travel and then slam/drops to the closed position.
Any clues as to whats going on here?
