Hi,
I have a 2009 GL550 that ran out of washer fluid the other day. I refilled the fluid today and the car still tells me to top off the fluid. I tried a using it a few times to see if it needed to get the fluid "flowing" and then after 2-3 tries the system stops responding and won't try to spray nor will it wipe the window. If I turn the car off and on, it will try again 2-3 times, but then stops again. If I try it with the car off and listen closely (key on), I hear a "clicking" like it's trying to active the spray, but no sound of a motor that I can tell.

I looked for a fuse specific to the washer spray, but don't see one, i only found fuse 100, 30amp for "wipers".

Any idea on this? Keep in mind, the front and rear washers worked perfectly prior to this.

nope get a new washer pump not a used on but a real pump

Thank you! Just curious, did the act of me letting it run empty kill the pump? I need to take the car into the shop for something else, so I'll let them handle it.

There are two (2) fuses for the wipers: #60 (5 Amp, in the trunk fuse box), and #100 (30 Amp, in the engine bay). So, check your other fuse.

If both fuses are ok, then troubleshoot as per the following link: Troubleshooting Mercedes Windshield Washer Problems

Thanks, I'll check both fuses this afternoon!

Washer pumps frequently fail ... they aren’t really heavy duty items and consequently aren’t so expensive. A blown fuse is almost always indicative of a component failure ... not a fuse failure.

well, took care in today and the mechanic tried it and it was working perfect! I’m guessing when it went empty for a few days and it was so cold something froze up. After it warmed up a bit it started to work. Thanks all!
