Hi. My 1998 C240 estate seems to be acting wierd. All works fine then it won't open from passenger side with remote key,opens from drivers then the passenger window and mirror dose not work. Disconnect the battery reconnect all is fine. Then will do the same sometimes from the drivers side. Sometimes you have to open it withe the blade of the key. Car will start and drive fine. But then it will have no indicators horn windows mirrors. Do a battery reset and all is fine for awhile. Very annoying. Could anyone shed any light or experienced this. Thanks.
