This is the dismantling manual I found.
As always, a disclaimer that it can be a dangerous process and your Lexus might not need it. if you see the instructions in the SB above, only vehicles like taxis might qualify for the amount of use you would have to be doing in order to have to clean up the blower once in a while.

i wish that i could find out for sure is this fan at the top of my 2016 HV battery or is ti only 2013-2014 cause the two posts that are above say those years specific and when looking online at HV EV battery the 2013-2015 have differnt part number than the 2016-2018 so im now wondering and trying to find out for sure about this
so am i understanding correctly that to get to the fan if it is in my car where the lsits say it is going to be though the trunk not the back seat ?

thank you for the link to this I appreciate it it helped me with a good portion of my questions
after watching this video
i am wondering is my back seat of the ES300H 2016 support to flip down like that or do I need to take the entire back of the back seat out of the car not just flip it down and then also remove the paneling in the trunk
the fan I didn't see it assembled on the battery when I saw them dusting it off so is it right to think the fan sit on top of the battery to the left ? or is that incorrect been looking trying to find photos of the fan on the battery where I can find it on the 2016 ES300h but cant seem to find a full assembled picture that shows that clearly so I know what to do
and I'm happy to find out that I don't have to dissemble the battery at all that helps me to feel safer about this.

I read that post and the guy says he got close to 500k before having to change the 12v battery. I find that hard to believe and credibility of the post is in question because he's in texas just like me. The heat and humidity is the arch enemy of batteries and I've been through 2 12v batteries in 100k miles. No way in gods green earth I'm getting 500k miles out of the 12v battery under the best driving conditions. 😏
omg maybe if he drove 500k in 2 years perhaps
but i don't think that's going to happen
my 2016 was just a few months under 4 years old with 37k when I bought it and the battery tested bad the 12v

Fan is the white box sitting on the top left of the battery. When you look at it from behind.

i don't want to sound like an idiot here
its just whats confusing me is I guess with my learning disability if id not see the exact process of it being done and it has to be detail like have to see steps for it in my car how to get to it and see how people do that so that i can copy what they are doing in real life than its very hard for me to learn and understand how to do it.
i even called up a Hybrid Battery company called priusKings in Utah asked them if they could do this for me what they would charge for the service and the reply i get back is
our tech does not have parts for lexus form someone who clearly doesn't speak English well
then explained i don't want or need parts its not bad its fine just want it cleaned
i get a reply saying our tech does not work on Lexus vehicle
im like the first instinct is to reply and say you Stupid Iginorage Idoit B are so dumb you can't even understand English to say hey lexus is Toyota and if your name is prius kings then yous should be able to work on lexus
take my money do what I'm asking your to do as a service but no i did not say all that but i wanted to.

Yeah i called some guys too. A few know about it others don't as it's too new. But take a look here. You should create a video too on how to clean it. You can see him disconnect the fan on this 2014 lexus es300h. See https://youtu.be/4V4ypK3F2rY
it is a little overwhelming at first a bit fo anxiety over will I be able to do it without doing more bad than good
im the guy who put the computer back together and I forgot to plug the internal battery back into my laptop I realized so had to take the entire laptop apart again just to do that all because I wanted to upgrade the ram lol.
BUt i think I can do this.
my question is since I'm not taking the entire battery out all I'm going for is the Fan to the HV battery do I even need to remove the back seat at all ? bottom or top
or should I be able to get that fan out without having to remove eth ebakc seat parts also ?
another side note off this topic
i spoke with Dave one of the forum administrator and he said that when he has a moment near the PC he will start to work on a separate area for the ES hybrid since the other models have them he will work on that for the ES also

You are giving people here too much credit if you think they will be able to properly post only hybrid-specific question on the hybrid forum and all other questions in the general forum. From my experience such division only creates more mess. The only result is that now you will need to search two forums for any questions instead of just one.

Having a bank of information related to the ES hybrid would be helpful and probably stimulate posts related to it. I actually have to search through other model forums to get hybrid specific info. Mods can always move posts. Why open it up to other models but not the ES?
