My 1978 Rolls Royce Corniche convertible (45,000 miles) soft top does not go down or up. The motor and hydraulics are apparently ok. The shop has dismantled all the soft top hydraulics and pumps again to have them re-checked.
What else could it be? Any possibility that it is an electrical issue?
A few hours before the top refused to go up, the driver's window stopped working. The reset in the fuse box did not help. Then suddenly, it worked again.
After the first inspection of the hydraulics, it was all put back. The top would actually go up but not down. Now it has stopped going either up or down.
It has been months since I had the car. The shop could be out of their depths here. Any suggestions?
