I had to remove half of my lower dash to replace my cabin air filter, I think they should hold car companies accountable for poor design choices

[leonardsmith]

Scotty; that was one of the best descriptions of how air conditioning system works. Most people make it sound a lot more complicated.

[spydroptics]

This guy is the absolute best at explaining things so that everyone can understand. His tips are priceless

[evengarcia]

I learn more from your videos about cars then I do reading the books thanks Scotty.

[StrikeFreedom]

Dude the timing of this vid was spot on! My AC ain't working well so I'll give your suggestions a try! Thanks.

[aprylshowers]

I'm a recently divorced single woman & I tinker with minor fixes in my car.. so just wanted to say thank you for your good advice, plus you make me smile because you are so hype when you do your videos. God bless you & the fam.
Peace

This is the way YouTube should bee. Great, simple, useful.

Scotty, this A/C video is great. As vehicles become more and more complicated by electronics and the requirement of specialized tools, it’s good to have folks like you to simplify what otherwise could seem complicated and overwhelming. Thanks. I do, however, have a question regarding your insistence on having a strong battery to ensure peak A/C performance. Correct me if I’m wrong, but I seem to recall you stating in one of your other videos that, once the engine is running, all electricity needed then comes from the alternator, not the battery. I also believe that the alternator charges the battery. Right?

Scotty reminds me a lot of Doc Brown from Back to the Future! Haha :-)

[WildGosdanArmenia]

I don't know why i am watching this, my car doesn't even have air-conditioning😂

[thecokerfamily]

Keep those videos coming!!! You are the best and look out for the little man! We watch you everyday! We are going to share with everyone we know! Thanks a lot Scotty!

[caseywinehouse]

Man I’m so glad you made this video. My 2006 Dodge Ram hasn’t blown cold air in a few years, and it’s much too expensive to take it in to a shop to get it fixed. They always try to up sell me on crap I know I don’t need. It’s only recently I’ve started getting into working on trucks and cars, so this will certainly be my next project. Thanks Scotty!

Who else's air conditioning system is working perfectly but is watching this because they like watching the Scotty Kilmer channel? REV UP YOUR ENGINES!

[sjohn]

If your AC doesn't work on a German car, throw the entire car away....trust me

[rtdreep]

Thank you Scotty! I followed your steps and observed that the radiator fan was not spinning. Local mechanic confirmed it, and replaced the assembly. I'm grateful to you!

[ArtisticDazzler]

I have learned so much about cars just by this one video! Maybe now I won’t have to wait on my husband to fix it 😂 Thank you Scotty!

[oliverrojas]

Always been confused by AC, but this video is one more step towards clarity

[being_frank_with_you]

My mom's cabin filter hadn't been changed in 10 years! It was a solid black brick of dirt and leaves! She was complaining that the air smelled moldy. LOL

[casperskafs]

THANK YOU THANK YOU!!! I've come back to this video just to tell you I never knew about a cabin filter. My 99 subaru foresters ac stopped blowing cold a few years ago. After watching this video I found the cabin filter and IT WAS INSANELY DIRTY. Huge mouse nest and leaves. After cleanin it out my air is ice cold again!! Who knew 5 mins of my time would fix my ac. Thanks scotty!!
