Not getting any power to the windshield washer pump(front or rear) wipers do turn on, but no fluid. I've seen lots of threads about the pump not turning off but haven't found solution to no power.

I pulled the reservoir out to get to the pump. Applied 12v and ground both ways, and pump functions as it should.

I Have checked fuses inside and under hood all seem to be good. I swapped the relay with another but no luck. Relay does NOT click.

Pulled the switch for the rear wiper and it has power and output wire has power.


Anyone experienced this? Could it be the wiper motor even though the wipers work correctly?

 

Mine is dead as well. Went out about the same time as the seat heaters and power seat.

How did you get to the pump? I haven't tried to take mine apart yet.

To get to the pump I had to take the entire resevouir out. Unbolted the brace/hours bump that sites over the top of the reservoir and removed the air filter housing. Pump is on the back side of the reservoir.

I went ahead and checked the wiper motor module and it was definitely corroded, tried cleaning it but made no difference. Ordered a new module from Amazon hopefully it will be here tomorrow, and I can find out if it will work out not.

I hate shotgunning parts, but haven't seen another solution except for bad wiper modules.

 

Had a similar problem with just the rear washer and it was a corroded washer module (see pic)

In my case I desoldered the washer module PCB and some of the relays on the underside, there I found some of the PCB tracks had been eaten away, so jumpered out the tracks, cleaned up the PCB and it works fine. A new module is expensive in the UK, sounds like your new module should fix it ... Good luck, keep us posted!

 

Just an update. The module PCB was roughly $60+ from Amazon and solved the problems that I was having.

 

Glad you've fixed it, good job

Wish I could have got one for $60...
