Question: I own a 1981 Rolls-Royce Corniche Drophead Coupe. The windscreen wipers have always parked nicely aligned at the bottom of the windscreen after being turned off. Now they have suddenly started to park at about 30° sweep angle. All seems to be OK at both continuous and intermittent wiping, and there is no excessive play in the wiping mechanism. I would very much appreciate any advice, thank you. 

Answer: I would suggest changing the wiper rack CD5395 this is the tube that bolts into side of motor all you have to do is remove wiper arms so wheelboxes can turn as you pull the rack out this could be neccesary as parking switch broken on rack. We hope this helps.
