SL55/63/65/R230 AMG: 2003 SL55 AMG AC/Heater Blower doesn't turn off
The EIS IgnitionModule has been checked, The rear SAM, the front SAM and the driver SAM havebeen replaced still won’t read or communicate with the diagnostic. The Shop I took it to gave up after spending hours and hours trying to find the problem. this all started after one of the batteries going dead and I replaced both.
