Chasing this gremlin but could use some help. When I wash the windshield with the standard beams on, they dim to almost off then come back when I release the washer. It doesn't happen with high beams or the fogs. No idea how long it's been happening as I just noticed at night. No changes to the truck that I think might affect this.

anybody seen this before?

Thanks!

 

They actally dim or is the water jets blocking the light? Mine dim but it's because the water is blocking the beam...

 

Well Holy Cr@p!
I honestly don't know, but I'm going to look tonight!
Crazy that the stream of water wold block the beam and it would look light the lights dim so much.

Thanks for the good lead!
