Nice video, easy process to do, great that you have such direct access to evaporator...cheers!

Another tip is to turn your ac off but keep your blower on high for a few minutes before you shut the car down to dry the coils off the smell comes from moisture that accumulates on the coils from turning hot air cold

Nicely done. I will have to look into this.

Klima is a unique product for sure. I have been using this for a LONG time, even before Nextzett had it when the German Company EINZETT owned the rights to the product. It's a great product to use once per year on your vehicle to clean out the interior portion of your heating and air conditioning system. Removes a vast amount of the "musty" type smells and conditions and cleans your system and REMOVES or neutralizes the odors using their proprietary system which is quick and easy to use (for the most part). If you have a musty smelling vehicle, give this one a shot, you may be very surprised at it's effectiveness provided you follow the instructions on the package.

我没有等泡沫完全干透，没有装上滤芯然后装上小盖子并以最大风量运行风扇，你猜发生了什么事情，那些泡沫从小盖子旁边的两颗螺丝附近渗漏出来，滴到车的金属底盘上，这种情况我不知道我的2021款的MY是不是有问题

Have you thought to check and see if someone like K&N makes reusable filters so you don’t have to keep replacing them?

I use an ozone machine .
