So I bought a new car and knew the front wipers and pump don't work .
On further research i read it could be the sam

Does anyone know how I could test it and any where near to get it repaired

Please help
 
No one knows :/
 
It will need to be hooked up to diagnostic equipment called star, any local Mercedes specialist near to you should be able to help
 
Well i would think that op first port of call would be the fuses ......>>>>
Things that go down like this must be coverd by a fuse to start with .

Thank you for the reply :)

I have checked fuses 11, 13 under bonnet. All ok,

Does anyone have a link to a fuses layout ? maybe its a relay

i have it booked in tomorrow with a guy with a star kit, will he be able to see the faults on the SAMS?
 
So tonight I checked over fuses all ok.

The battery was not connected securely:/ now I've secured the negative terminal all is ok battery side.

Still no wipers tho. Is there a way to check my self if it's a SAM unit ? Like power to motor ? Etc

Thanks
 
You could be looking at a heater resistor and a combination switch, or a sam or an ignition switch or water ingress it could be loads of stuff, you really need to let a specialist look at it.
 
or check bonnet is shut as it cuts power to wipers

Thanks.

Does anyone have the electrical drawings for the c lass c320?

I can see the bonnet switch but can check its closing if i see where it goes,
 
Juat alam the bonnet firmly my c class had wiper problem and it was vonnet not shut tight
 
Thank you,

I have taken it to a a garage and they say its not the sam unit, but possibly the rain sensor?

looks to have had a new windscreen?

Would this stop the wipers all together ?
 
so tonight i unplugged the front fog lights, i checked them with a 12v batery all good,

checked the plug read 12v, however when i plugged them in didnt work

any ideas?
 
Well of anyone is following this and has the same issues with the fog light.

I have had to fit s load resistor. As the guy before obviously didn't buy canbus led fog light strips.

Now the dogs are working
