Hi there, I have noticed that my climate control now does this too. It's annoying having to reset the controls on every startup. Did you get yours fixed?

Yes, drying out the evaporator definitely helps. I just need to make it more of a habit. Out of interest, does anyone have any a/c cleaner aerosol recommendations? Having used the Toyota/Lexus one cited my original post, I'm really not that keen on its 'perfumey' smell.

Since my original post, I've taken the advice of members and I've found that that running the heating on max for about an hour really helped eradicate the foul smell. Now when I use the a/c for cool air, I always try and switch the a/c off, heat on high for the last 5-10 minutes of the journey. I've also disabled the recirculation mode as I found that was keeping the moisture in. Appreciate that this isn't ideal, but if it keeps the smell at bay then I'm going to continue. Running the heater on high temperatures during the winter will hopefully also help.

Thank you @royoftherovers Much appreciated.

Cheers @chris1601 I'll park it in the drive with engine on, switch the heating on max heat, leave a/c off for 30 mins to see if that makes a difference. Do I need to have the A/C switched on for hot air to circulate around the evaporator? Also, do I keep the recirculation switched off? If this works without any maintenance then I'll be chuffed! 😀

Thank you everyone for the advice. I think I'm going to definitely use the a/c on auto more, then run it on hot once the weather cools down and change the pollen filter. The Lexus air con cleaner looks like its worth a punt, will get it up on ramps to locate the drain holes, hopefully this month. If any one has any recommendations on which interior smoke bombs are good then please let me know. @Jayw13702 may I ask which fogger you have? Looks like the smoke thoroughly goes everywhere in the cabin!

Hi everyone After searching for a recent thread on how this can be resolved I thought I'd see if anyone else had a similar experience/fix. On my 2014 Lexus IS300H, I've noticed that if if the A/C is on regardless of the air circulation setting it does not smell. However, as soon I switch the A/C off the smell that is emitted via the vents is vile. The A/C blows ice cold, but in the winter I do notice that the windows 'steam up' more often than in my previous car. Especially on the rear screen. So far I've tried spraying the pollen filter area with Dettol Antibacterial along with each of the vents, followed by running the a/c on an off on a high heat setting for about 30 minutes. The pollen filter was changed recently and when I took that out there was no smell. I've also checked the small black rubber hose in the passenger side foot well, removed it and some water came out but quickly dried up in the recent heat. I've read that spraying a specialist air con cleaner such as this (https://www.lexuspartsdirect.co.uk/parts/lexus-ux/lexus-ux-2018-present/lexus-ux-cooling-heating/lexus-air-conditioning-system-cleaner/) via the drain pipe could help, but not sure how big of a job it is to access the pipe from underneath. Any advice or fixes will be appreciated. Thank you.
