Whatizzit ??
 

I already did a search and came up with nothing much about washer pumps. I am in the middle of replacing my w/s washer pump and there are two wires, one black and the other black with a blue tracer, imbedded in the hose going up into the hood. It looks like a heat shrink wrapped connector of some sort but it wasn't connected to anything nor did it look like it had been for a while. The pump itself is crapped out, I can see the corrosion through the plastic case and already bought it's replacement yesterday. '91 300SE w/ headlight washer/wipers. The headlight system is working perfectly so it is getting power. Any ideas anyone?

Thanks in advance, going back out to finish putting the new pump in, check back in a little while.

Hey - Ya know I drove a '78 Dodge Aspen wagon for 3 years and fundamentally the major difference between that car and my '94 MB wagon is when I heard a funny noise in the Dodge I turned the radio UP and now when I hear a funny noise in the MB wagon I turn the radio DOWN and say uh-oh what's that!

How true, how true dtf, I was just wondering what those wires are for. New and strange noises in my Benz do tend to cause me to investigate them, it's too good of an automobile to ignore minor problems. It'll take me a couple of days to change out the other parts I bought yesterday then an almost perfect Benz for my daughter to learn to drive in. :eek:

Bruce, your car has heated lines to the windshield washer nozzles. Those might be the wires to the heater elements. This came up a couple of days ago. Check the archives.

Hey Bruce,

Sixto is right. The lines are automatically heated when outside temp requires it. The wires you see recieve current on the nozle side and are connected to nothing on the pump side.
BTW are you shure your pump is cracked out ? Mostly it's the rubber washer underneath it that's gone. Easy to check, easy to replace and cheap!
You can simply pull the pump out ( straight up as it slides into a dovetail fit onto the reservoir ) to check this out. I paid $24 for the pump almost two years ago.

95300YDT-A, yup, pump is gone, I momentarily swapped the power over from the headlight pump and nothing. The rubber washer was good but had already bought a new one with the new pump and to prevent any problems down the road...... Works a lot stronger now, just gotta figure out how to adjust the nozzles so I'm squirting the whole windshield and not just the top of it, even at highway speeds. (I KNEW you'd think that I didn't think......) ;)

Bruce,

The nozzle is in fact a little steel ball. When you put in a needle that fits in the small hole, you can move the ball in its seat and reoriantate it as you wish...
Use the back of the needle and don't put it to deep.
