:cry:
I have a 1995 C280 (South Africa) and have had some strange electrical faults.One recently was a misfire and was quoted by the agent the equivalent of R 14,000 (1,400 pounds) to renew the electrical engine harness, due to degradation. Due to the high costs, took to a private auto elec who did it for half the price. The MB delaer was unwilling to help, despite it being a known problem, this depite a fsh. Subsequently, a similarly aged C 220 was done with full compensation from MB, for the exact same problem (Bio degradable wirring??)
Also, recently, my exterior radiator fans were running continuously, without the a/con being swithched on. Suggestions was that the viscous fan was losing its 'tightness' and the viscous fluid was renewed. Problem still persisted. The 2 switches, one being the water temperature sensor on top and the other being the a/con temp switch. with a hit and miss diagnosis, the temp switch for the a/con close to the chassis was replaced - the fans are still running at the slower speed - disconnecting the water temp switch has not helped - any other areas that would cause the fans to run, even in cold weather without the a/con being switched on?

Ok, looks like I got th problem sorted out. I took back to the auto elec who has been working on it before and found some of the wires to be shorting, causing the fans to fans to run, even in cool weather. The wires (bio-degradeable) have been patched and re-sealed and hopefully, OK .
