hi.. i have a 1993 300se mercedes and my wipers stop working how can i tell which wiper relay need replace. i cant guess because the cost to much thanks for the help i really need it.

The 140chassis wiper relay is located on top of the front fuse box. The connector is known for corrosion problems. Pull the harness out of the relay and check for corrosion. You maybe able to clean the contacts but most have to be replaced.

ok.. thanks for the info sir.
