I recently had work done on my clutch, I noticed I had no power steering or controls on the steering wheel. I hade a new clock switch fitted but all I managed to recover is the horn. I’ve also tried having the car coded but the mechanic has said he can’t do it. Is it possible when the clutch was being removed they have damaged a switch or equivalent under the car?? Any suggestions would be much appreciated 👍
