Hi,

I have a Mercedes W210 2001 Facelift.

I have a problem that I can not figure out. When I'm blinking and having a passenger with the seat belt on the turn signal is flashing faster than usual. When the person takes off the seat belt the flashing is at normal speed.,If the person takes it on again its back to flashing quickly. All the turn signal lamps is flashing quickly.

Only noticed the problem on the passenger seat.

What can cause this problem?

 

it might be helpful to know which light is blinking. when you continue to say "I'm blinking" I'm sure that is imprecise

 

Sorry, I forgot to mention that. Its all the blinking lights, rear and front

 

What he's trying to say is, the turn signals are blinking at a faster pace when the belt on the passenger side is in. And when the passenger takes the belt off, it's back to normal.

 

Yea, pretty much
