300 SE Residual Engine heat utilization
 

My REST Remains On All The Time And Won't Go Off Until The Battery In Drained. WHAT IS CAUSING THIS? HOW DO I RESOLVE IT? IS This On A Separate Fuse Circuit?

Programming issue in the A/C controller. MB issued bulletin back in 1994.

Replacing the controller is the only fix.

Thanks
 

Thank You Very Much. Mb Doc You Are The Man!!!!!!! No Mb People Are Up On That Service Bulletin. I Have Been Try To Get An Answer For A Year.

I guess you could switch the power supply & eliminate the system UNLESS you live in a HOT climate.

The SI was number MBNA 83/48 dated April 1993. Can e-mail you a copy if you want it!

same car 300SE. ALL FUSES HAVE BEEN REMOVED AND BATTERY IS STILL DRAINING VERY FAST. WHAT COULD BE CAUSING THAT?

You've probably already removed the positive cable from the battery and checked for a short to ground, I'm guessing?

Thank M.b. Doc. I Am A Retired Guy I Don't Have $1,100.00 In The Middle Of The Month To Replace The A/c Controller. I Am Using The Following Work Around. When I Park My Car For The Night I Take Out Fuse # 18 That Stops The Electrical Drain. I Put The Fuse Back In When I Drive.
