    So based on all the information presented, we can confidently say that it is indeed a beneficial practice to run the blower and engine for a brief period after turning the AC OFF in order to dry out the evaporator and prevent mold and corrosion, right @KDH? @hasithayad? @topkollek?
    I agree that running the blowerfan can help reduce odors and harmful microorganisms, but I’m not sure it will make the evaporator or other air conditioning parts last longer. running the blowerfan for extra time could actually shorten its lifespan, and replacing it is a PITA because it required to take out the dashboard. also, it could drain the battery since the alternator is no longer running and the blowerfan is completely running on the battery. :confused:

    Mold growth definitely matters because it retains moisture, which in turn speeds up corrosion

    Eh? the blower fan would keep running either way, it's just that we turn the AC off about 5 minutes earlier than the blower fan

    Furthermore, the blower assembly can be replaced by simply removing the glove box in most cases, without having to take off the dashboard. Replacing an evaporator is 100 times harder.

    also, it could drain the battery since the alternator is no longer running and the blowerfan is completely running on the battery. :confused:

    You misunderstand. The advice is to switch off the AC approximately 5 minutes before you reach your intended location, with the blower running.

    Doesn't matter the order but turn off your ac before you leave the vehicle if you have a decades old vehicle. It becomes much more forgiving on battery and starter motor when you are turning on the engine next time. You do not have to do this if you don't have an extremely old vehicle.

    You'll always get two camps. Ones that don't, ones that do.

    Rather than saying there are no benefits, the statement actually emphasizes that running the blower with the AC off "provides additional protection" particularly in climates with high humidity and the AC is highly relied upon, such as in Sri Lanka.

    Given that it only requires a simple button press, why not do it?

    මේකත් හරියට කොන කපන එකද හොඳ කපන්නෙ නැති එකද හොඳ වගේ ප්‍රශ්නයක්. දෙපැත්තටම තර්ක කරගන්න පුළුවන්.

    ඒ සී රෙපෙයාර් කරන තැන්වල දවස ගත කරලා තියෙනවා මේ කියන 'මෝල්ඩ්' මොනවද කියල මම දැකල නෑ. සමහරවිට එහෙම දෙයක් ඇති.

    එකපාරක් වාහනේ ඇතුලේ පට්ට ගඳයි. හොයල බැලුවම ඇතුලේ මීයෙක් ගිහින් පදිංචි වෙලා.

    You have a point. but from what I know, evaporators are made from materials like aluminum. according to chatGPT, some evaporators also have special coatings to protect against corrosion, moisture and refrigerants. So, I don't think turning off the AC for 5 minutes would make much of a difference.

    based on your screenshot, the volvo afterblow function runs the fan for about 30-40 minutes. my LG AC also takes 30 minutes to complete its drying process. do you really think just 5 minutes will be enough?

    Nah water does accelerate corrosion, that's one reason radiators made out of aluminium require coolant that contain anti-corrosion inhibitors instead of water even in tropical climates

    Read again, it says the blower kicks in 30-40 minutes AFTER shutting down the engine, not that the fans run for 30-40 minutes

    Oh, my mistake...

    you’re right. it seems that turning off the AC and letting the blowerfan run for 5 minutes is beneficial (y) ;)

    It looks like you're micromanaging, and it’s PITA for me :lol:
