I got a Lexus gs300 year 1998 and I found clean water in the driver's side. I check and is not antifreeze fro

Do not you have warranty? Just take it back to the dealer and ask that question.

It could be coming from the AC evaporator, due to condensation and drain alleys are clogged. Check also the AC status through the sight glass, it maybe low on freon.

most likely its water from the Evaperator in your AC system. The drain tube is prob clogged or off where it mounts to your HVAC system.

Take it to a shop and have them either clean out the tube, or reattach it.

Worst case scenerio you have a leak on the seal of your windshield.

Good luck!

Sorry..it was not clean water.. your window was cracked.i had to go..badly.maybe a heater core leak.

It can come in thru a windshield is molding leak. Take a good time with good light to inspect it. If you find something weird, get clear silicon and cover it up.

There are drain hole in the bottom of the door that are designed to allow the drainage of water that might run down the window glass during a rain storm. Over time these hole may become clogged causing water to run into the footwell.

Could easily be a bad heater core.. if you dont fix it yourself the dealer will charge you like $2-4k in labor alone if it is not under warrantee.. pray it is not that.
