I just purchased a 2002 Ram 2500 that needs some help in this area. Instead
of trying to work around and under the dash and disassembling a bunch of
things that do not need to be taken apart, I’m going to repair my truck the
RIGHT way and remove the entire HVAC module. To watch the YouTube videos
you’d think that all Dodge pickups have these failures all the time. They
don’t. I suspect that a LOT of the problem with those that do is that the
owner doesn’t follow the basic instructions to turn the
heater/air-conditioner OFF before turning off the engine. It makes perfect
sense to me that if you leave everything on, the next time you start the
engine the air doors are going to be moving forcefully and instantly to
their stops instead of moving more slowly and gradually the way they would
if the system is OFF at startup. I’d also speculate that the reason the
dealerships quote or charge “outrageous” amounts of money for their repairs
is that they realize that the HVAC module is a SYSTEM and that when ONE
part fails it’s only a matter of time before ANOTHER part fails. Shop labor
rates and lawsuit rates being what they are, I’m not surprised that some
dealers charge $2500 to fix a Dodge HVAC system. Obviously they’re
replacing the ENTIRE module assembly and they’re not risking their profit
or reputation by replacing one or two components in a high-mileage SYSTEM
that probably failed as a result of operator error in the first place. I
also find myself wondering how many Dodge DASH CRACK problems are the
result of improper HVAC operation. Because once again, I’ve been around a
LOT of Dodge pickups from late 80s models through the later 2000s and NONE
of them have had dash cracks. My 2002 I just purchased with HVAC issues
also has a cracked dash. Coincidence? I think not.

WRONG… The failure has nothing to do with cutting the HVAC system off
when you stop the engine. The failure occurs because of the excessive
forces during the system calibration routine that drives the doors to a
stall position to find the extents of movement. This occurs automatically
based on the engine on/off count(10 on most models).
The failure is a “wear out” mechanism, but not dependent on age, mileage,
weather conditions, or user adjustments…just on/off. A pizza delivery
guy will fail faster than grandma taking eggs to market every Saturday.
Replacing the doors with OEM plastic will just fail again. HeaterTreater
provides a method to replace the doors without removing the plenum box.
Even if you want to remove the box and replace the doors, you’re still
better off using our steel doors instead of plastic that will break again.
A lot of professionals don’t like to break open the refrigerant system,
drain the radiator, remove the steering wheel, etc. because of the
liability of putting it back together without missing a wire, creating a
rattle, screwing up the radio, or a thousand other potential problems. We
prefer to just let sleeping dogs lie, but if you think your truck is a
candidate for the Barrett-Jackson auction in 20yrs, it’s probably best to
keep it stock…
The cracked dash is from UV light through the windshield and totally
independent of the HVAC system. Just because there are two problems
doesn’t mean that they are related.

Thanks, I took it to the Shop and they wanted to charge me $400.00. Im into
this project for 1/2 hr so far, I figure 1 hr to reassemble and Im done.
This is Great, Now we have AC for our Trip to BC 🙂 Thanks Very Much

Thanks, so often YT is the best source of info for fixing vehicles!

These videos were perfect. It was awesome to bring the laptop out to the
truck and watch the videos while getting to actually look at in person. I
got very lucky and only had the recirc door broken…. which in turn made
my ac blowers blow very little air. I made the cutout, reached in and
grabbed the broken door, and BAM. The AC was blowing full blast. So again,
THANK YOU for these great tutorials.

@raceman19901 Read their guide on what doors to replace. It will tell you.

funkydunky1 says:

Lol they used so many screws so it wouldn’t squeak over time like vehicles
that only have snap in dashes.

Texster Allen says:

Removing the door leaves the external and internal intake ports open. At
highway speeds air flows into the external port and directly out of the
internal port…like having a window rolled down all the time. The fan
doesn’t have the power to overcome the air flow. No door kills AC and heat
efficiency. You can block one or the other port, but it doesn’t allow the
computer to control the door and “dry” out condensation or maximize
AC/heat. Replacing the door with the HeaterTreater kit is best

I have a 2004 Dodge Ram heat only coming out the middle vents. After
looking at the service manual I started to Panic as I read how the door is
replaced. Disconnect the AC, the Heat and tear apart the Dash…there was
NO way I could do that I needed my defrost desperately. Using your video I
was able to cut open the box and tape the door in the up position and
reseal things temporarily so I had defrost while I waited for your parts to
arrive. Thanks for your product, you are the BEST!

Thank you for making this video! I’ve been needing to do this for a few
months, and now have the information I needed to get started.

Just got done replacing re circ door. Bought it from Heater Treater for 130
shipped. Took about a hour and half. Not bad at all. Used a few tricks of
the trade to make it really easy. One screw on the door motor can be a
pain, but overall its really easy if you have mechanical skills.

cappy032 says:

To anybody who is having the problem where only air blows out of the vents
but no defrost. Your problem is the mode 1 door is broken. I have a 2003
Dodge Ram heavy duty and I am replacing the mode 1 door because it has the
problem I described above and when I took it apart like the video shows,
the mode 1 door connector spins free.

Just got the parts this morning, done by noon….This part really works and
for anyone thinking about getting it and saving a ton of money!!!!!! Dodge
wanted 1400 dollars to do the work…and replace it with shitty parts..that
would need replaced again in a year or so….watch the video it really is
that easy
