Does anyone have problems with the headlamp washers? Sometimes it works, sometimes it doesn't. I was in Tahoe for New Years and didn't work when needed...

 

Were your headlights on?

 

Was there water/washing fluid in the washer jar. If there was water it was most likely frozen since this happened in Tahoe.

Otherwise I would take it to the dealer to check the Headlight cleaner motor or relay circuit

 

When you pull the wiper/washer stick toward you to wash the windshield, if the headlights are on (or in automatic after dark) the headlight washers will do their thing. Otherwise to engage the headlight washers only, you have to push that little button ahead of the gear selector next to the heated seat switches.

Since I'm not in snow and slush very often down here in the Texas tropics, I really don't need those headlight washers - they just came with the (what I consider mandatory) heated seats. Because I'm not often a mud-bogger, I don't often need to wash my headlights, but pulling the lever after dark usually make me smack my head as it can totally screw up a good wash job by spraying the lights, hood and sometimes the windshield with washer fluid.

Wish Lexus would disconnect that interlocked control - and let me choose whether to wash my headlights or not.

 

Hmmm, wonder what year we are talking about? In my '05 330, the ONLY way to make the headlight washer come on is to:

1. have the headlights on
2. push the button on the lower, center dash between the seat warmer buttons.

Is yours different in that they come on with the activation of the windshield washer? On my new BMW 3 series, the headlight washers wash after every 7-10 activations of the windshiedl washer. I have heard different numbers, thus the variance.

 

Mine didn't work until I filled the WW washer fluid container back up with almost a gallon of fluid. The WW washers worked fine. SO, my guess is that maybe there are two different feed tubes so the headlight washers don't run you out of fluid.........Just my 2 cents.

 

The headlight washers on my '04 RX 330 (April '03 build) spray when the headlights are on and I pull the windshield washer stalk. They can also be operated independently at any time by pushing that button just forward of the shifter, beside the seat warmer rotary switches.

 

Yep thats the only way!!! if your lights are OFF and you clean your windshield the headlamp washer will NOT spray--But if lights are ON and you wash the windshield they will Spray!!
OR push the button as stated above at any time

 

Wow. That is a huge change from the observed operation in my '05. I wonder why they changed? Anyone with an '06 care to share how theirs works?

Thanks,

How does yours work then?

 

Uhm, what I initially wrote when I responded?

"In my '05 330, the ONLY way to make the headlight washer come on is to:

1. have the headlights on
2. push the button on the lower, center dash between the seat warmer buttons."

I have had my car for three years, actually read the owner's novel (sorry, manual) and know it pretty well. That is why I am surprised at the difference between the '04 and '05.

SO If your lights are on and you pull to clean the windshield your washers do not come on? They should My 04 did as well as the 08

 

Thanks guys! I think that b/c my lights were on "auto" so it may not be on when I test it since it is during the day time. Now its working fine! I just thought that it would work since the windshield one works when you press on it at anytime.

 

Pardon my ignorance, but is it the same on the 08? I was unaware the headlight washers were able to be activated by any means other than the manual switch on the dash. If driving with the lights in auto mode, but they are on due to darkness, if I pull the wiper stalk back to cleanse the windshield, the headlight washers come on? I haven't had the vehicle long and have yet tried or needed to try to operate the headlight washers, knowingly.
Thanks,

 

Yep the headlights will get a wash too
