Hello my name is ***** ***** i will do my best to help you , i strive for EXCELLENT service and nothing less. If you have your wipers set automatic they will wipe once every time the car is started and then periodically as you drive to let you know that automatic wipers are on. Make sure the stalk is in the O position. As for the horn , the contact or airbag may be slightly loose so as you steer or hit a bump it will accidentally sound the horn. To tighten or remove airbag you just need a 2-1/2 Inch long t30 bit and you can unscrew the 2 screws from behind the steering wheel.

They both go off at the same time and it does not happen all the time and when I start the car the wipers do not go on it also happens when car isstopped

Stopped as in the key is not on ??
Customer: replied 2 years ago.
Key is on stopped at light it is light the horn and wiper is an alarm or so

Ok here's the options. 1- the steering column control module located inside the steering column. Or the left front fuse box control module called a "left front Sam". Does this happen when it rains or is wet or humid outside ?
Expert:  Lou P. master tech replied 2 years ago.
hello, just following up with you, Lou
Customer: replied 2 years ago.
It happens whenever there is no set time sometimes it does not happen at all weather is not a factor
Expert:  Lou P. master tech replied 2 years ago.
ok, so all the systems inside a mercedes work off of communications and lots of modules, there is nothing that is not controll by a control module inside a mercedes, so the left front sam ( signal Aquisition module ) is connected to the underside of the left fuse box and that is what activates the wipers and horn . now if you can start the car and rotate the steering wheel and adjust it up and down and in and out and bang on it , see if theres anything you can do to set the actions off, if not then the fault is most likely inside the sam and will need replaced, they are really easy to replace and you can probably find a used one on ebay, it will need to be coded to your car but if you get lucky you may find one from another s calss with the same options and not have to code anything. but that is probably going to be your issue, does this sound helpful?
