s500 coupe wipers
 

Can anyone tell me the location of the windscreen wiper relay module on a W140 s500 coupe. On the intermittent setting (position I) the wipers do not cycle smoothly; seems as if the relay is switching on and off quickly causing the wipers to 'stammer' across the screen. On wiper positions II and III the wipers operate normally.
Many thanks in advance for any info.

Here you go...
 

The intermittent relay is attached to the wiper motor assembly.

The wiper motor is located in the cowl area, on the driver's side.

Good luck! Hope this solves your problem.
