My windshield sprayer does not work. Pump and fluid OK.
Disconnecting the sprayer nozzles verifies pump is OK. Nozzles clogged? Tried to unclogg. There are some electric wires to the nozzles. What are they for? Car is a 1994 C280.
Help please.

 

OK. No replies. I cleaned the nozzles with a long thin sewing-needle. It helped. Still do not know why the wiring?

 

Heated washer nozzles on most MBs. Not sure when they came into being but probably before 1994. Suggest you disconnect the supply again and try some compressed air into the nozzle to flush any debris back out the way it went in.
