We've had our GS430 for a month now and wanted to see how the headlight washers spritzed. Pushing the headlight washer button didn't have any affect. Is there a control setting someplace? Seems like a call to the shop is is order.

 

I think the headlights have to be on. Thats how my ls works.

 

that is correct lexusls430.

 

Interesting, I didn't find anything in the manual. I'll give it a try tomorrow.

Thanks

 

Lights have to be on for sure.

 

From this, could we assume that the power for the headlamp washers is tapped into that of the headlamps?

Hmm...
