Yes. Had this happen a Micra my mother had about 8 years ago.
Yep, I just noticed it in my 03 rx 300 yesterday. Has anyone out there found the culprit, and fixed it. Where would the aircon drains be?
I've also heard that the Windshield wiper grill areas have drains in the front firewall that can get clogged up, causing water penetration into the cabin area, common on a lot of cars, not just lexus, my dads camry had it, really hard to fix, had to remove the dash, to find clogged drain pain, drain hose clogged.
