Crank shaft position sensor is bad. This is the most common failure. Its location is on the rear drivers side of engine, where the transmission bell housing mates to the engine, only one small bolt and a two prong electrical connector hold it on. Usually will not throw a trouble code. If you remove it you can test it with an ohm meter, will have an erratic reading or read open loop, can malfunction intermittently or permanently after parking vehicle and won't restart. Applying some heat source to it during ohm testing with a hot air heat gun will usually cause the sensor to read open loop if your not sure if its bad or not. This reply is probably way to late, but I just happened to come accross it while online. Harry (master certified MBZ diagnostic tech)

most likely dirty switches or bad fuses. Try rotating fuses and then try moving them again. Corrosion on the fuses cause "gremlins" in the system. If not find a junkyard and pull out a set of used switches or try autohausaz.com for new replacements.

Check the underside of your hood for a belt diagram. If it's not there, call your dealer with your VIN number to get the correct diagram.
