Windshield wipers AND sprayer not functioning.
checked wiper fuses (32 and 33) under hood.
Having a hard time finding any info on wiper relay location.

 

Pump probably failed. Most folks never use them due to the mess.

 

I had the infotainment panel out a month ago and forgot to plug in one of the connections.

 

Sorry for digging out that old thread... but my sprayers are not working neither, even though the wipers are functioning...
Are you referring to that pump #3 in the diagram?


Thank you!

 

Yes, #3 is the dedicated pump for wiper spray. I would check hose routings for kinks before condemning the pump. Open the hood and manual latch the hood latch. Then unclip the hose at the passengers side hood hinge to verify it hasn't kinked.

 

I tried running it with the hood open, no juice coming.
Will the car not spray if it detects the hood is open?

 

Correct, no wiper/washer operation with hood open.

 

Thanks for the info!

I’ve pulled up this thread because I have the same situation as the original. To emphasize: NONE of the functions condoled by the wiper stalk are working. No intermittent wipers, no regular wipers, no washer. Zip.
I recently pulled the infotainment panel, removed the nav unit, and installed a “Mr. 12 volt” Bluetooth upgrade for audio streaming. Put everything back except the nav (I used the nag’s power plug to power the Mr. 12). Put everything else back together. Mr. 12 seemed to work. A few days later i hit the wash button on the stalk. Nothing. Uh oh. Tried the stalk in every position and nothing worked. Fortunately it never rained on the trip. Got home, found this thread, pulled the infotainment panel and made sure everything was solidly plugged in. Still nothing. Desperate. I pulled Mr. 12 and reinstalled the nav unit. STILL nothing. Virtually everything else in the cockpit works as it should, so I’m at a loss for what to do. The 3 fuses associated with the wiper system are fine. Suggestions?

 

Following up with the fix that worked for me. It turned out to be a weak female PIN number 2 on connector 0428 at the back of the Centre Counsel Module (CCM). More detail:

—The CCM is occasionally mentioned in the shop manual but it is not well defined nor is the location described. It must NOT be confused with the Central Electronic Module. The CCM ls found at the back of the vertical panel housing the clock, the radio display and the a/c controls. It is a black plastic box attached to the tear of a white box that houses the 3 rotary ***** for climate control.

— 3 separate female connectors slip into cavities on the back (firewall side) of the CCM. Looking at the back of the vertical panel, from left to right the connectors are numbers 428, 429, and 430.

— Connector 428 has 20 female pins. Looking at the connector's face, Pin 2 is the second one in from the connector’s right side. It carries the 12v switched, positive power that runs to the wiper control on the steering wheel. In my case, no 12v emasculated getting to the wiper switch. Female Pin 2 was not making a good contract with its male counterpart in the CCM module and no current was flowing to the wiper stalk. The female Pin seemed a bit loose in its cavity. Sometimes you shore these up by sticking a separate wire in from the connector’s rear, taking away the wiggle room. I did this and apparently got lucky, as the wipers have moved from totally dead to fully operational.

— Except for 428/pin 2, all of the wires from the wiper switch/stalk run to the CCM at connector 429, which is a 10-pin female connector.
