Tonight I had an interesting electrical hicup with my 2003 MCS. It has xenon lights. When I started the car and turned on the lights everything but the actual headlights turned on like they should. Driving lamps and fog lights could turn on but nothing else. I then flicked the switch again and they started up.

So I drive off and begin to turn the heat on and to my suprise the entire control system for the heating/cooling is dark. I figure okay, no big deal just hit the auto button. No luck. At the next stop light I quickly turn my car off and back on and everything operates as normal.

I am chalking it up to computerized systems needing a reboot . I will watch it a little over the next few weeks to see if its an issue. I have 9 months left on my warranty.

Anybody ever experience any of these issues?

 

Once my aircon system in my 2003 MCS had a similar issue, wherein it was dead when I went to use it. After an engine restart, it was fine and never it happened again. I always forget to tell the dealer about it, if it never happens again I will continue to forget.

 

Last night I was driving home and the the control system for heating/cooling went off. Simply turned the car off and it worked great. It has only happened to me once.

 

Been posted about here many times. In each case, turning the car off and on fixed it. For most, it's so rare that they don't worry about it.
