Vinod's rear wiper stopped working. So far his mechanic has replaced the motor, a coil, and a switch, to no avail. What can they try next? Car Talk suggest he try a different mechanic!
Dear Car Talk
Shirley's defroster seems to make her engine run rough. Has Car Talk ever seen this before?
Robert is looking at a VW Tiguan, but he really prefers diesel. Can he just buy the car anyway and swap in a diesel engine? Is this more trouble than it's worth?
