When I try to turn them on only the wipers move. I hear no motor trying to push water. I checked the fuse box and it said number 48. There's no fuse! Duuhh that's the problem, NOT! I put a fuse in(correct amperage) and still nothing. I'm so confused and my hands are too big to put a multimeter in there.
Just plugged in my Schwaben tool and I got a code, A6D3.
What should I do? Motor burnt out?
UPDATE
Using my Schwaben I was able to find the activation for the washer motor. When I do the windshield nothing happens, when I do the headlight washer(don't have them) I hear a relay click over. Bad relay?

Why are you asking this in the stereo section

Why are you asking this in the stereo section.
Are you using the correct fuse map for your year
of car?
Was is working before?
Check fluid and Hoses would be my first step.

People either pull the fuse or code the headlamp washers (assuming your car did originally have them which is a possibility and the bumper was replaced) to be inactive (clean car mod). Sometimes these amatures can do it wrong when deleting the pumps or maybe those pumps need to be worked every so often or they get gummed up (assuming washer fluid was in them when they were coded off years ago) with old fluid and 'algae'. Yes they have been an issue with algae/mold build up in the E90 washer system that blocks the fluid and create havoc on that entire system.

Looks like you are going to have to get inside the passenger fender and do some work! It isn't easy to DIY and it isn't cheap!




BTW wrong section for this ish!

I had no idea where else to put it. The washer pump using electricity and it said electronics. Yes it was working before I went on deployment 7 months ago. I checked fluid and its full.

More likely a clog or disconnect than electrics

More likely a clog or disconnect than electrics.
Pull hose just behind the spray nozzle and activate to see
if any fluid comes out.
Remove hose from pump activate and see if fluid comes out
then.

"Windshield washers spray a very low volume of fluid, or no fluid at all.
The strainer (arrow) on the windshield washer fluid pump may
become clogged by debris or an algae-like substance.
The algae-like substance is typically caused by using non-approved
washer fluid or straight water in the washer fluid reservoir.
To replace strainer:
• Remove washer fluid pump, located in lower part of right front wheel
well.
• Drain existing washer fluid in reservoir and properly discard.
• Replace strainer, which is installed on end of pump. An updated
strainer has a larger mesh to avoid future occurrences.
• Refill washer fluid reservoir with BMW washer fluid at specified concentration.

Do the wipers work?
Do the headlight washers open?

The wipers do work. I don't have headlight washers. I think that I have the wrong fuse diagram in my car and that its just a blown fuse. it says its fuse 48 but there is no fuse in that spot.

I do. It says that fuse 48 is the one for washer pump, washer pump heat, and headlight washers, but there isn't a fuse there.

Fuse 48 is only for the headlamp washers.

Fuse 48 is only for the headlamp washers.
See diagram in previous post I added the circuit diagram
the main pump motor does not appear to be fused.
Well at least fused by itself. See the diagram it looks like
f50 runs it and a bunch of other stuff.
