For about a week i have heard clicking behind my dash on my 92 300sl. It sounded like a relay constantly switchng on and off. My auto electrician figured it was the climate control unit behind the dash.
Anyway it continued to click after it was disconnected and finally went up in smoke when i was on the motorway ( literally ). I asume the relay eventually got stuck and burnt out.
The climate control / heater now doesn't work at all and as a by product the radiator fan is constantly on. I notice that the interior heating system shares the same fuse (which hadn't blown) but can't see why the system wuld have caused the engine fan to be constantly turned on.
Can anyone help? Any advice would be good.
Thanks
Tim
