52 yr old grandma here! This is my son's truck I lost him in 2019. I've spent 2 winters with no heat because none of my mechanic friends wanted to break the dash because of sentimental reasons. Thank you for the video! I did it myself aside from someone disconnecting the ac lines and helping me move the dash! Took me about a total of 3 hrs. I had to take a few breaks. You guys were great! By the way,,, I did NOT break the dash 💖

[@TallFamilyFilms]

I'm officially feeling a little less manly as this took me 12 hours (although I did have a few trips to the auto parts store, but still…). Sorry to hear about your son - I hope his truck runs forever for you!

[@jmemixx]

You rock grandma

[@blaineanthony4066]

Gangster granny!

[@chrissantos7865]

Aside from the ac and the dash lol that's the hard part granny

[@DasMoose9001]

Much Respect!!

[@WildBill541]

10 MM 8 MM T20 torx 7 mm 13 mm Phillips Flat head AC Line remover sizes 5/8” and 1/2” Was making my tool list, I figured I’d share. I already did this a couple years ago and asked my dad if I should swap out the evaporator while I was in there. He said if it ain’t broke, don’t change it. Later on that year, it started leaking in the cab. So I definitely recommend changing both when you’re in there 😂

[@natethewrench]

Very nice, no nonsense/ no frills, no music lead in or bloated introduction. Loved that you named off the sizes of everything. Just meat and potatoes. Great Job dude.

[@kammason6619]

well done walkthrough, i like that you just right to th' point and didnt chew up 10 minutes of video self promoting cheers!

[@sirj9]

Fantastic video. Standing ovation!! I have a 2005 Ram 1500 I rescued from NJ and the A/C is not working. Given the neglect of the previous owner, I am considering rebuilding the entire HVAC system using OEM parts. Thank you for taking the time to share.

[@TallFamilyFilms]

I cannot thank you enough. This was my Bible as I did this and I looked at a LOT of videos. You've got a great way of explaining things. My toughest things were stupid but time consuming. The top part of the dash (the flap) was glued to the windshield - I assume the windshield was replaced and they used too much glue. That took me an hour. Removing the AC lines was no that easy as the space was cramped. Removing the heater core lines was horrendous. They were really stuck. Then the blend doors - ugh. So many trips the store(s) to get the right ones. Thanks for all your help. I would have never gotten this apart.

[@383yj]

This is the best video on KZbin for this job. I will be doing one for a friend this weekend and this will help immensely. While I have done many of these, none have been on the Dodge 1500, now i have an idea what I am getting into. I see way too many people cutting the lines and using rubber hose and I just want to yell at the monitor. Nobody has patience to do things right anymore. Anyway, great video, keep up the great work. You are doing a great service to others on here.

[@NoNonsenseKnowHow]

Thanks man! Really appreciate your comment and feedback. Glad to hear the video helped out and good luck with yours!

You are doing Gods work, Before I was quite intimidated to do this with my ram 1500 - but now I think my wife and I can knock this out in 3/4ths of a day.

[@NoNonsenseKnowHow]

Haha, I'm not sure about God's work but I'm glad to hear the video gave you some confidence! Once you tear into it it's really not a bad job at all. I recommend taking pictures or short videos along the way so in case you get mixed up going back together. That's great that your wife is going to help you out with it! Good luck with that, and let me know how you make out

[@crandallwoodworking2988]

That was quick, but detailed. It will probably take me a whole day to replace the evaporator and heater core, but the video helps me to keep everything in order. Thanks for the video!

[@billnull3113]

Well done! You had a lot of steps to deal with and you ran through them pretty quick but you were so thorough. Thanks a bunch.

Thank you for your video. I was able to take the dash off my 2004 Dodge Dakota SLT Quad Cab and replace the heater core saving me about $500.

[@NoNonsenseKnowHow]

Awesome man! Good to hear you found it useful and got it done! Thanks for the comment!

[@TehShadowDeath]

I'm about to do all this to my 06 today. I had already decided I was going to do this a few months ago because the heater core started leaking a year ago. Well last week I turned on the AC and it coated my windshield in oil so it's a good thing I had planned on replacing both while I was in there.

I’ve been putting this off for a while thinking it was going to take days to do can’t be without my truck to long i watched this video before and during finally gave it a shot best video I’ve seen 👍 it helps if you get all the tools Ready definitely recommend using a small impact or drill following his lead teardown took me an hour and 15 mins dealing with alarm and brake controller it’s really not as bad as it seems I almost got it all back together I’m estimating maybe twice as long I’d hate to miss a wire lol

[@NoNonsenseKnowHow]

Erinmalyce hey, thanks for the comment! Honestly to give you an accurate answer on your question I would have to be looking at one in front of me. It really depends if there's going to be enough room under the hood and such. I think you would be better off just doing it the way I did in the video honestly. It's really not that hard once you know where everything is. And especially if you have a friend helping you you can get it done in a breeze.
