I purchased replacement washer nozzles for my 1989 300E. My old nozzles have
3 wires, plus the water tube inlet. Two of the three wires lead to a harness
that runs to the underside of the fuse box. The third wire connects to a
heating wire that it embedded in the washer fluid tubing coming from the
The replacement parts have only two wires. I spoke to two Mercedes Benz
dealers parts departments, and confirmed that this is the correct
replacement part. It doesn't make any sense! Do I leave one of the three
wires disconnected? Do I need to connect the odd wire somewhere else???
Another issue is that the old nozzles have ~120 degree bend in the water
input connection. The new nozzle has no bend at the water inlet.
Any help would be greatly appreciated!
