We have a 1993 Mercedes 400 SEL. The climate control unit has a problem where it will keep turning on and killing the battery.We have been disconnecting the battery cables every time we shut down for more than a short time.Now other problems are occuring such as the ASR and ABS lights are on, and we are having difficulty with the way the car operates.Any input is greatly appreciated.

The ASR and ABS are voltage sensitive, so each time you disconnect them from power, they will reset. To cancel the ASR light, start engine then turn steering wheel full lock to right, then lock to left...ASR should extinguish. ABS light should then go out once you drive above 8 mph for 100yards or so. Until you can have the climate control looked at by a professional, I would locate and remove the fuse for it when you park up. Much better than disconnecting battery.
