wiper problems!! please help
Hello anyone out there that can help I appreciate it! I drive a 2004 c240 the other day I was driving and all of a sudden my wipers started going crazy like it was raining heavy. I turned them off then turned them back onto auto. The next day it started to drizzle wipers didn't turn on. The only time they come on is when I push the knob in the use my washers. I checked the fuse for the relays for the wipers it was good. Is it my combination switch or could it be my relays?

Perhaps there is dirt on your windshield. There are four infrared LED's by the rear view mirror. There are also four sensors. When dry the light reflects from the outside surface of the glass. Water drops on the glass change the optical refraction angle and the light is bent away from the sensors.
You can check if the LED's are on. After dark use your camera phone to observe that area of the windshield. The LED's will glow in the camera image.
