Wow, I had to get this far before this comment. I thought that it would be sooner in this thread.

They may not know where the on/off switch is for the wipers, but they should have at least seen them when they wash the car..

I replaced mine also. It's under warranty, but it's just a $23 part, and a twenty minute R&R if you have the tools organized. That's about what it would cost me to Uber to/from the dealership, plus they don't get the opportunity to break something else in the process while doing this job...like they did when they changed one of my TPMS sensors.

To add something of value to this thread, the bolt on the bottom of the plastic wheelwheel piece that needs to come off is a 7mm, and the 3 torx screws that need to be removed are T15. A standard blade screwdriver will be useful for removing the wiring connector, and a flashlight might be of value, though not completely necessary. There are no clamps holding any of the lines on, or holding the pump in place...it just snaps into the plastic surrounding it.

Be prepared to get wet if there's any window washer fluid in the reservoir. A finger placed over the hole asap, and the new pump within reach to quickly plug into the hole will reduce the loss and mess.

My wiper fluid has stopped spraying as well on my 2017 at 12k miles. I checked to make sure the fuse was good and that the hoses were clear of debris.
Thank you for the information. If I had the spare time I would probably replace it myself, but at least it sounds like it won't take the dealership long to replace the pump.

This just in and yes I am bringing back this thread from the dead. My 2017 Z51 stopped working at 3200 miles. Just dropped it off at the dealer today very nervously. Why? because I never used this dealer before but I am taking the advice of my neighbor who had his past 3 vettes serviced there.

HOPEFULLY it’s a simple repair like stated in the post above. Im still under warranty so should be covered plus I’ll have a chance to see how this dealer operates when I return for my next oil change.

Please respond if you have had a failed wiper motor on your C7?

The dealer did well. Had me in and out in 2 hours. Faulty washer pump.

Part number 22999423

Replaced under oem warranty and they treated my car well..mileage in 3721 and mileage out 3721.

Thanks Hampton Chevrolet of Hampton,VA.

I had a failed washer pump on my 2016 Z06 last year, bought with 5400 miles on the clock. I systematically went through the controls and switches to see if everything worked just after I bought it. Took it to the dealer in August and it was replaced under warranty. All the tech said was that it was dead.

Waking up an old thread with a question.
Is the windshield washer pump referred to as the headlamp washer pump ?

E Z06

Anyone replaced the windshield washer pump ? What brand did you purchase ? Part number ? I looked at Rock auto and they have 2 different names although they look the same. Windshield washer pump and Headlamp washer pump.

nwalker

The short answer is no. They are 2 different part numbers. Apparently, headlight washers is an option on the C7. The GM part number for the WINDSHIELD washer pump, at least for my 2016, is 22999423.

Not uncommon. That's the same part number I used for mine as well. Got it from Amazon in two days, and it's real easy to get to.





Apparently they were redesigned to correct this issue.

Wow, and I thought I was the only person who tries to fix defective parts, I don't feel so alone anymore.
PS Just realized I've had my car almost a year and a half and have never tried the wipers let alone the washer. Need to drive this thing more (at least in the rain).

May be an old thread, but thanks for the info on the pump. Will save this for future reference.

Also bought mine from Amazon. Mine was/is still under warranty, BUT, due to the cost (about $16.50 from Amazon), plus the fact I didn't want anyone mucking with my car (the wheels have never been off), I decided to do it myself!

nwalker

Thanks for the heads up on tools required!
Mine was also under warranty, however, I didn’t mind spending $16.50 on Amazon, and an hour of my time, to do it right, myself, so I didn’t have to let someone work on it that didn’t really care about what he was working on. The wheels had never been off this car, and I had just rather do it, myself!

+1 another happy customer here, thanks for the info on this thread! One thing I didn't realize, is that the little rubber sleeve needs to be popped off of the old pump and onto the new one - I had a completely full reservoir and no helper (and wasn't planning on "catching" the fluid). Unfortunately the hose side popped off, vs. the pump side, so it was a little tricky for me to get it back onto the hose while keeping one finger on the pump outlet to try to keep as much wiper fluid from spilling as possible.




I also "fixed" the old pump afterwards by shoving some old wire into the outlet side, and then applied 12v power, it un-jammed quite easily. So, next time (and there will be a next time), I'll be sure to either have a helper, or, just plan on catching the fluid.

nwalker

I left the grommet in the reservoir, and pulled the pump out and pushed the new one back in. It made for a much smaller “hole” with much less fluid loss!
If it had been an expensive fix, I would have had it replaced under warranty. As I stated above, I’m very happy to have not had someone else mucking with my car...you can’t tell it was ever into!

Here is the part number used for my 17 c7

Read about a lot of C7 washer pumps going bad.
