Question Details

2003 e500 both heated seat switches start flashing 5 seconds after turning on switches.  Aux battery & main battery are at proper voltages & alternator is putting out 14 volts.  No codes in the seat heater module.  Using star for diag.  Any suggestions?

Try doing a full system scan and see if there are any codes. Also is there any chance that any module have been replaced? If the module is not programed or lost programing it could do that.
