Greetings ,
windshield reservoir is full , pump sounds like it’s pumping , but no spray coming out of nozzles
I pulled off the cowl and a few lines , could not see any thing out of ordinary. I did try to blow thru drivers side with no luck , are the nozzles replaceable ? Any thoughts ???

Thank you

 

Have you tried spraying with just the feed hose and nothing attached, just to see if the fluid comes out of the feed hose?
The parts are replaceable or you can clean them. I think it's section 8R-30 in the service manual.
The part number is 5099970AA (This is the heated version with the wires).
They are available at Rockauto and e bay.

My right side nozzle just sprays to the cowl and no pressure behind it. I bet it's clogged but haven't figured out how to fix it yet. I tried poking around in there with a paper clip etc but haven't had any success. Maybe I should just buy a new one 🤔

 

Watch this you tube video. This may be the answer.

 

You can also try what the guy in this video did:

 

Thanks. I’ll give it a try 😜

 

If at any time plain water was used in the reservoir slime occurs and this plugs everything up. In this case the tank has to be removed and the pump, fluid level sensor and hoses have to be cleaned. I had this when I got my car.
Try removing the lines from the nozzles and pump fluid through them.
The nozzles can be cleaned by blowing air through them.
The fluid jet can be adjusted with a paper clip in the hole, the nozzle is a ball and can be removed by snapping open the nozzle body.

 

What is the way to actually remove the nozzle like the guy in the video and submerge in vinegar? I'd like to try that method. Don't think it's the reservoir/pump as the right side works like a charm but the left side doesn't.

I'm assuming the nozzle head can be detached from the hose?

 

I found a video on you tube. You can try this or check the service manual in the tech section.

 

Thanks, I knew you can pop it out with a screwdriver, but can the nozzle head be removed from the hose without breaking it to a) put the nozzle piece into vinegar and b) maybe maybe blow some air through the hose?

 

It looks like you can disconnect the hose. If yours has wires, you could probably push air through from the connector or use a large syringe and push vinegar through it.
Here's a picture of the dorman replacement nozzle.

Is there a MB part number for these? Unless I missed it in the post, all I saw was a Chrysler part number?

I bet it's just clogged at the front nozzle piece so I will try to fix that first. If I really can't figure it out, might be time to pay the $100 (or hit up a junk yard) to purchase assembly, hose, connect all in one. Thanks for your help!

 

There are 2 part numbers for the SLK 320;
