Wiper and Tail-light problem
Just bought a silver 330, 2004 with 90k for 11 grand. Pretty happy with it.
Few problems, the intermittent wipers don't seem to work. I notice the auto function, that doesn't seem to work either? The other wiper settings seem to work just fine, any thoughts?

More on the wipers, the car is equipped with "auto" mode. It was pouring down rain last night on the way home and in the 1st stage on the switch, nothing happened regardless of the amount of rain drops on the windshield. Other features work just fine.
Still looking into the high brake light issue, it seems to work off and on.

I would have to dig into the wiper issue. But for the 3rd brake light, Push the brake light assembly to the passenger side of the car i believe, and pull up to remove and change bulbs.

Simple enough, I will replace the high mount brake light.
The wipers, I read that its possible to reprogram the switch so they function like normal interval wipers, is this true? Is it something I can do?

Just found this:
"Yes...here in Texas we have drizzle too! Lexus "rain sensing" wipers are a JOKE. They suck. I want my ES300 intermittent wipers back. I'm totally disappointed that Lexus would put such a poorly performing feature on their automobiles. It shows that poor engineering and product testing was done before committing to production. A big BOO to the Lexus/Toyota engineering team for this lemon.
So I just spent two hours figuring out how to solve the problem. I won't bore you with the details but what I figured out is that if you DISCONNECT the rain sensor the ECM unit (which controls the windshield wipers) will think that the "rain sensing" option is not installed. In this case the ECM reverts to speed adaptive "intermittent" mode. Hurray! That's just what I wanted! Above 20mph the intermittent period will shorten and below 20 mph it lengthens.
The wire going to the sensor module has a latching connector. Squeeze the latch properly and the connector will unplug.
Presto! You're done! You now have speed-adaptive "intermittent" windshield wipers. The adjuster ring on the wiper lever sets the wiper period.
I call this the "Charlie in Texas" mod. "
