I have 1997 Mercedes C200. Recently the air-conditioning failed and required a replacement. A auto-shop offered a good price and we went for it. After the installtion, the car was never the same; the car overheated and smoked. They fixed it a couple of times, replacing pumps, etc. A week after the electrical circuit smoked when driving and a fuse melted wiping out half the electric system. The auto-shop tells us it is not them who caused it.
Question: Can replacing the air-condition and tweaking the colling fan, etc, be associated with the electrical wiring? Should they be responsible for fixing the "damaged" electrical areas? The damaged area included car locking, indicator light, radio, etc, however, the dashboard, main light are still working. Please advise.
