I just did the cabin air filter replacement and cleaning today using the Tesbros kit. Went quite well thanks to your installation video. The trim removal tool that I got (I purchased the kit a few months ago) didn't have the "teeth" for pulling the clips underneath the dash but I had enough fingernails to get them out easily. This definitely is a twister of an installation. See photo of my old filters blow - yuck! I couldn't get a good enough view in there to figure out and remove the wiring from the filter cover but luckily I had enough slack there to get the old filters out and replaced. For my screw removal on the filter cover, I used a ratchet wrench with a 3 inch extender and a Torx T-20 tip. This worked great and once the screw was loosened, I could just use the extension by hand to finish removing the screw. Worked well in reverse as well. I also had the situation as another reviewer - cleaner blasting out because I had the fan on in the car. Reminder - turn off the fan before spraying the cleaner inside the system! It was one of those humorous "Whoa!" moments when I realized what was happening. Thanks for your kit with great instructions - another winner for Tesbros.
