Joeyj Posted June 26, 2018 Share Posted June 26, 2018 I am a new owner of a 2002 ES300 and on the 1st long distance trip discover a lake on the rear passenger floor. I googled and found nothing for the ES300 that was helpful. So, this post might help others. Under the vehicle on the passenger side you will see a rubber grommet and a small hose should be sticking out. That will be the AC drain hose. That needs to be cleaned out. My problem was no hose was visible. I removed the grommet and stuck my finger in the hole and felt the hose. Needed a needle nose to get at it but once I pulled it out water began dripping. Problem solved. Hard pack snow or an ice chunk probably pushed the hose up in a kinked position. Quote Link to comment Share on other sites More sharing options...
Loubna Noureddin Posted February 17, 2020 Share Posted February 17, 2020 I'm having the same issue with my RX 350 2010. So what do you suggest I do? Quote Link to comment Share on other sites More sharing options...
