    Very good video.

    It's amazing that this has been a common issue with these trucks since the early 2000's and they're still allowed to make them like that. The government needs to stop protecting these big companies and start making laws to protect consumers from these issues.

    Great job. Great explanation. I think Ford Escort had the easiest heater core to replace with the 2 screw access door, and the Dodge Ram has the most difficult. Although I seem to remember an old Buick or Cutlass required pulling the passenger fender out to access the heater hose connections. I like a challenge but I hate desigh stupidity. Thanks for the video. Cheers

    Do you know where I can get some of those South main auto magnets from my toolbox I'm just becoming entry level mechanic

    That is so Chinsy They give you foil tape to cover what you destroyed wow If you took the time to chop and Dremel the case you could have taken the time to take the entire thing apart and done it right That's sad Eric O @SouthMainAutoRepairLLC

    hi. i would like to know where the outside cold air enters the heater box through the firewall. is there a way to block the cold air from coming in from under the hood?

    I know that Dorman is a hated brand name here, but I have to give credit where credit is due, especially with the Coolant Crossover Pipe and the Oil Cooler adapter for the 3.6 (2nd Gen) Pentastar Engines such as on my 2014 Grand Caravan. Dorman has OE Fix replacement parts that are made of aluminum instead of plastic (OEM).

    I do tons of ram HVAC rebuilds and that joke of a door and the box hacking is compliments of Heater Treater not a sponsor. Ive had words with them over using scare tactics like The Whole Dash has to come out etc. I can have the steering column and dash out properly before you can hack brackets and remove all the screws trying it their way. Also i use Blend Door USA on all my rebuilds.not a sponsor

    You didn't do anything with that noisy assed blower motor. Your fired !

    My pressure tester from the 70's still pressurizes the cooling system…Have another tester that sticks in the rad filler.. and tells me if head gasket is blown…chemical turns a different color when suction is applied.

    Holy crap, how bad is Dorman that their rep is still just as bad on current YouTube videos

    I got a question for you? So i go to switch where it circulating the air to doesnt work. Its stuck on the upper. I wont switch to feet or the windshield. So i cannot defrost the window

  16. Avataaar/Circle Created with python_avatars Luna 40 says:

    Nice vid man.I have a 97 dodge ram 2500 cummins every time i hit bump on the street it sounds like there's something loose inside the heater box could be one of flaps that could be broken? or any idea what could it be

  17. Avataaar/Circle Created with python_avatars Gary Meredith says:

    Eric if you're going to take this whole thing apart at least clean the parts cuz your one fresh air blowing on all that all that dust that you left on there come on .

    GOOD JOB….

    Eric have you ever done a video on evaporator replacement on a 2002 GMC Sierra 1500HD ?

  20. Avataaar/Circle Created with python_avatars paul ellis says:

    glad to see your daughter she is so cute an happy

  21. Avataaar/Circle Created with python_avatars P Lmmn says:

    Amazing, fabulous brain you have… and awesome patience. I've done a couple of heater cores and it is a whole new world behind that dash board… thumbs up to you.

  22. Avataaar/Circle Created with python_avatars Carl Kraus says:

    This year, 2021 I did a heater core replacement on my 2001 Jimmy. I sympathize with your dilemma. I didn't have the debacle you have but I still had to take the whole dash out. I had no idea what I was getting into, but it all came out okay, much to my amazement.

  23. Avataaar/Circle Created with python_avatars Alan Robison says:

    Great demonstration of how the blend doors work. I was always curious as to how they worked. I have a Chevy Silverado and have been having problems with heat coming out of the dash vents when the blower is turned off.

  24. Avataaar/Circle Created with python_avatars Joseph Hendron says:

    About how long did it take for the whole job? Have to replace my own blend doors.

  25. Avataaar/Circle Created with python_avatars Michael Brown says:

    Oh yes ,2002 ram "trk,🥴thing☹️" I call mine. 4.7, I have hot air floor pass,side ,. Cold cold floor driver's side ☹️. Help!!!

  26. Avataaar/Circle Created with python_avatars Mark Steele says:

    So that's "Ram Tough!" I wonder why he knows these things like the back of his hand?

  27. Avataaar/Circle Created with python_avatars _Mart_ says:

    I did that similar thing in my 99 ford f150. The blend door snapped of course. 10 hours of labor to pull the dash. Bought the new redesigned blend door, two piece METAL pin instead if plastic. Cut a hole in my heater box via the glove box took me around 1 and half hours and the heater box doesnt leak or nothing after taping with that foil tape. I wouldnt do that on a customers car but my own helll ya!

  28. Avataaar/Circle Created with python_avatars victor beltran says:

    Wel well very good job there wheel done am struggling with diagnostics on my mom RAM it makes a lot noise under the dust but thanks to your video I kind have an idea what’s going on in there but am afraid all have to come down to make sure are the blend doors but the low side in the Infineon compartment frost while the a/c is running I would very much like to hear what you think thanks for been there for us and do what you do Jahovah bless your every day and family what is really important

  29. Avataaar/Circle Created with python_avatars moon doggy says:

    usually really like his videos. but this one kinda pissed me off . he makes fun of the owner trying to safe money on fixing HVAC doors. 2002 through 2014 ram truck all suffer from these doors breaking. First doors are not cheap . he say he bought OEM just one door is almost 150$. not all are expensive as that door . he replaced heater core and ac condenser. but did not say how much those cost. I called dealer 1500$ in just labor not including their over priced parts. not including heater core or ac condenser. I fixed 2 doors with out take dash off and box. I wonder how much he charged to do that job.
    I fixed my with Dremel tool. was easier than having 0ay for parts and labor…

  30. Avataaar/Circle Created with python_avatars Kevin Dees says:

    I'm sitting here SCREAMING, take the air intake off so it's out of your way!!!!

  31. Avataaar/Circle Created with python_avatars jay s says:

    i had to do a heatercore on my last 2nd gen ram what a nightmare! the entire dash had to come out then the framework behind it to get to the core. 21hrs book and it took about all of that

  32. Avataaar/Circle Created with python_avatars Terence Hawkes says:

    Very interesting. Well done explanation. In your future you should be teaching. You have a gift.

  33. Avataaar/Circle Created with python_avatars ALEX says:

    I know this is a very old video but Eric. I've got to call you out on your torque specs . You clearly didnt give it 2 ugadagas meaning there's no way you meet the gouentight factory spec. SHAME 😄😄😄

  34. Avataaar/Circle Created with python_avatars Kevin Willis says:

    I missed the step where you put the mice in the heater box. Do you prefer oem mice or will dorman mice suffice?

  35. Avataaar/Circle Created with python_avatars Douglas Uhde says:

    you didn't say what part numbers, or how many total ndoors there were.

  36. Avataaar/Circle Created with python_avatars Joseph Hettiger says:

    I did get burnt on a spectre heater core that leaked after about a month so ill only go back with a mopar heater core unfortunately 4 times the price ive got pics of there's a way to post em

  37. Avataaar/Circle Created with python_avatars Joseph Hettiger says:

    I have said the exact same thing about cutting up the dash and HVAC plenum amd the Whole Dash has to come out scare tactics so i agree with you totally. I use Blend door usa on all of the one's i fix they are expensive to the tune of $300 a complete set but are a lifetime repair

  38. Avataaar/Circle Created with python_avatars Tom Sawyer says:

    In defense of his daughter that keeps interrupting him while he is making a video…. I was taught as a child never to interrupt grown-ups while they are talking. However, Eric never shuts up…he is a natural born motor mouth, so his daughter has learned as a survival tool to just interrupt him.

  39. Avataaar/Circle Created with python_avatars onefixitman says:

    I would have pulled that intake pipe but each person does it a different way and in the end it still gets done.

  40. Avataaar/Circle Created with python_avatars Texasknowhow says:

    I just kept thinking, "Eric, just take the dang air intake tube off!" it was so in the way. Hats off to you for working through all this and filming it for us… I have this job in front of me so was good to see from your video what I have coming. So a BIG THANK YOU for this. What did all this cost the customer? Just round numbers… Thanks, Clay

    I can't find the low pressure switch on my 2009 dodge ram 1500

  42. Avataaar/Circle Created with python_avatars MicheleRj Gross says:

    The good steel doors are the ones to get they will never break

  43. Avataaar/Circle Created with python_avatars MicheleRj Gross says:

    Oem doors are junk too

  44. Avataaar/Circle Created with python_avatars MicheleRj Gross says:

    That’s actually the good aftermarket upgrade doors and yes those actuators are MORE than strong enough to move the heavy doors
