Just had to get the 2 Front springs in my 307 replaced. The garage I sent it to called the other day to ask if I had noticed any issues with the wipers, which I hadn't. The mechanic said that something was off with the linkage when they were trying to remove it to fit the springs. They had the car over the weekend and I called them on Monday to see if it was ready. He told me that they had to fit a new linkage, which is costing me £135 and that the old one had cracked the windscreen when they were removing it. They are paying Auto glass to fit a new windscreen, but I can't figure out how a wiper linkage would cause the windscreen to crack?
