Vehicle system and function
The combination relay controls the left and right turn signals, the hazard warning light and the alarm flashing of the anti-theft alarm system. It also handles the wiper control (interval, flick wipe, after-wipe, speed 1 and 2) and switches the rear window defroster. In the wiring diagram it is designated N10 (W140) or N10/2 (R129). In trailer operation it takes over the turn signal monitoring with a trailer.
Installation location: In the fuse and relay box in the engine bay below the windshield; on the R129 under the cover behind the fuses.
Condition: Used genuine part in ECE version with trailer operation. Print on the housing: MERCEDES BENZ 140 820 71 26 [06], W.C 140/R129 ECE, 05 3904 00, 12V 2x1(4+2)x21W / 3x1(6+2)x21W, trailer symbol. Housing with slight signs of use, plug contacts bare. Price is per piece. The photos show a representative example.
How to recognize a defective part
  • ● Turn signal jumps into fast hazard flashing, the instrument lighting pulses along (often cold solder joints)
  • ● Turn signal stays on permanently
  • ● Interval wiper stops on the windshield
  • ● Wipers or rear window defroster cannot be switched off
