99 Dodge Ram AC fix vacuum tubing bypass firewall and dash!!!

Bypass firewall fix ac only coming through defrost under $10 #repair

[@tmc28]

I'm late to the party, but I just want to say thanks for sharing your knowledge. This solution brought my A/C back to life! It was a great feeling when the cool air came out of the proper vents. When it's 120 outside, it sure helps!

[@CMWeber88]

[@ericsych4146]

Great video,just got done doing this to mine. I ran my line across underneath seal against firewall. Zip tied it to wire harness and ran through fire wall by steering column. Total time about 30 minutes!!

[@ujfro6983]

Thank you for blazing the way for this repair. My main vacuum line broke off at the firewall entrance at the AC lines too. I had the same idea but needed confirmation of the line to run. I ran mine through the fender hole and thru an grommet plug in the door jamb. WORKS GREAT. Another gd Ram problem solved. Thanks brother!!!!

[@josephtruskowski688]

What black line on the switch do you cut? The one to the left towards the steering wheel ?

[@MrRico550]

My Man!!!!!!! You just saved me from a three day of research. I been having this problem by a few days and i just have Made the same you did. And it worked Three days dissasembling the dash and looking all the vacuum lines one by one jajajaja

[@chrisclark4037]

I'm having the same exact problem on my 1997 Dodge Ram Cargo Van. REALLY NICE ENGINEERING DODGE !!!! Thanks so Much !!!

[@CMWeber88]

No problem

[@dyrocoroots]

You my friend just saved me so much trouble. Days of researching, but I found your video. Thanks

[@CMWeber88]

No problem

[@jonm9461]

This video is great!! My vacuum hose broke right at the firewall entrance and I was not looking forward to the repair going through the dash. This will save me tons of time!! I'd rather spend a little time and the $10 versus probably $300 plus taking it somewhere. Thanks for the tip!

[@CMWeber88]

No problem

[@arod200834]

A BIG THANK YOU!!! This worked for me too and I also think its the best way to repair it. God Bless!!!

[@CMWeber88]

No problem!

[@Guneslinger]

Worked perfect, I just cut the line where it ran down to the vacuum block, spliced in the hose, ran it out through a opening to the left of the steering column where the electrical for the stereo and amp came through, over top of the brake booster and zip tied it to the electrical harness across to the passenger side, was able to also get that thing away from the exhaust by splicing some line over where the plastic ones are and routing it behind the kegger.

[@maxsands3861]

If I ever make a fortune I'm going to leave you part of it!!!!! I'm actually going to have heat coming out at the floor this winter THANK YOU!!

[@CMWeber88]

Lol

[@bretunderhill]

Thank you sir, my 97 dakota same issue. I connected the little hose from the t connector into the black hose on the inside of my cab and bingo!

[@waynehutchinson1423]

Bro, after roughing it thru Canadien winter and 3 months of summer heat waves,l was going to pull my dash apart.Thank you very much for your video.lt was great.You kept it moving,and showing everything.. Thanks again.l subed also.

[@CMWeber88]

No problem thanks!

[@robertwhite1131]

Great video!! Thanks for the quick and easy fix!!

[@josephfiumara9065]

Thanks for posting i have same problem with my 2000 dodge dakota i'm going to give this a try .

[@caleblivaudais7573]

Thank you so much for the video, I have been having the same problem, now I can fix it!!!

[@MrCarlosj0]

Looks like your video is saving me a whole lot of headache. I have an '00 1500 and I believe if you remove the glove box and reach behind the hvac you can feel the a/c core tubes so I am gonna try to feed the line through the same way.

[@jomine16]

Its 2023 and i just got a 2nd gen ram like this one and had the same problem. THIS FIX THE PROBLEM! HE IS A LIFE SAVER OMG LOL!. Im glad you posted this on youtube. Without this video I wouldnt be able to fix my problem.

[@CMWeber88]

No problem

[@ITW.Firearms]

Man just broke my vacuum line at the firewall. You are a genius

[@CMWeber88]

😂 idk about that

[@grcarpenter]

Thank you for the video I did exactly what you did and it works perfect thanks again

[@johnsiira9478]

thanks bro , i found snapped off original line that feeds in next the two a/c lines. so i just slid a loose line over that for now and works. this will be my next step later.

[@buddyrhodes1262]

Thank you worked great ac is back blowing cold

[@Oshinut28]

Duddee u saved me some headache!! I cant wait to do it just saw tis video

[@nm-zs2cd]

Thanks for the video, saved me about 800.00, my AC is working AGAIN!😂😆😁😄😃😀

[@robertinscoe2379]

4:26 video how cool is that. Nice fix👍👍

[@thesmallenginekid]

Thanks for the video. My vacuum line came off at the check valve. I could not figure out what was supposed to go to it. I guess the line fell back into the cab. My truck is really clean though. No cracks in entire original dash. Im going to try and go fishing.

[@jeremiah.b9008]

Thx man I appreciate the help, I had this exact problem

[@jmh4069]

Thank you for this video very helpful, I have a '99 durango 5.9 its doing the exact same thing, but the line that goes thru the fire wall looks visually ok, could it be that they just get clogged?

[@keithmyers247]

Did this on mine, but avoided drilling a hole in metal. There's a body plugin a factory existing hole in the door jam/hinge area. I ran the new hose through that. I now get flow from all settings, rather than just the defroster vents. Still have issues with lack of heat though. Minimal heat on lower 2 fan settings, gets cooler on settings 3/4. Flushed core both directions, didn't get much crud out. Temp gauge is where it's supposed to be. My truck is a March 98 production. I've read there was a change in design at some point in 98. I don't have the electric blend actuator under the dash.

[@SmithBrosServicesLLC]

I know, 2 years old, but I flushed my core too, not much crud, and barely any heat for the past 10 years.Changed thermostat too made no difference. Mine is a 1-98 extra cab but no rear doors.

[@berkeleyharbin1787]

Y’all ever find a fix for this? My heater doesn’t work, but the core flows fine, and no issues with the thermostat.

[@xKmotx]

I gotta give this a try. Been blowing out my defroster for 2 years now and I have tried finding the bad vacuum line. Heck, just replace the whole thing! Thanks for the idea! 👍

[@CMWeber88]

No problem

[@verdaderocristiano2486]

Gracias por estas experiencias nos ayudan mucho

[@rickeystiles9098]

Thank you very much just fixed mine

[@jordanrowan2537]

I might give this a shot I think I have a blockage in the black line inside the cab getting no suction at the control

[@STREETRACEN4U]

I cant tell if you purposely removed the dash to fix this issue or its just destroyed from the sun like all older dodge dashes are 😭😂 great video

[@robertdickinson2882]

I have the same issue. A/C only blows through defrost. I will look tomorrow to see if this is the same fix. Thanks.

[@MrOliverAC]

I have the same problem...my vent vacuum line melted. Is it a lot of work to get the vacuum line through its intended hole? I dont want to drill unnecessary holes.

[@willwebbjr]

Dude..... you may have saved my sanity. off to the parts store!

[@erickcruz6583]

I have the dodge 1509 1998 sport 5.9 and I only have ac or heat to the flor and and front class do you think I cab fixed the same way how you did

[@martonnemeth6881]

Can some please confirm if this worked on a 2000 Dakota? Thanks!!

[@jesserodriguez5617]

Oh god 🙏 I love you man thank you

[@MrYAMAHA32177]

I may be doing this soon myself.

[@BIGFREAKY69]

I'm having trouble with my 99. Ran 5.2 ac. It blows only to the floor and defrost.

[@thea1team85]

This method still works great?

[@leonardolopez9005]

So I have the same issue , and I think it’s causing my truck to have a rough idle and loss of power. I hope this fixes the issue.

[@juiceybananas5489]

I was having some of the same problems with my 99 Dodge Ram2500 Van. After hours of frustration I finally found the ultimate solution for my HVAC problems and that was to pour lots of gas all over it out in the farm yard and put around a 1000 shotgun ,.22 and other various caliber hand gun and rifle rounds into it , then sot a bottle rocket into it and WOOF! up in smoke, didn't burn real good. On the next Monday or tuesday I called Ardnt's auto recyclers to pick up a freebie, the man asked what was wrong with it , I told him it was shot. I bet he couldn't believe his eye's when he picked it up, it looked like Swiss Cheese.

[@CMWeber88]

😂😂😂

[@garymorgan168]

Good job Thank you 👍

[@MrRik10a]

should be able to use the heater ports at the firewall,,just a thought

[@RA-zq1xe]

THANK YOU SO MUCH

[@juliand2709]

hell yeah! Thanks so much!

[@CMWeber88]

No problem

[@georgecolbert3247]

The vacuum tubing on mine broke at the firewall. Must be a weak spot. The plastic was a bit deliriated too.

[@HankGoodness]

Thanks for the brilliant idea! Where to get the tubing? What size again? 1/8 id or od?

[@CMWeber88]

Hank Goodness Napa and it’s a id

[@garystoner8947]

Thanks helped me

[@CMWeber88]

No problem

When turned on the ac blows hot air after the ac comes on for a few seconds

[@hillaryclinton2415]

Gonna try this on my durango... Same problem..

[@garymorgan168]

Yes Truck like my Dad 2001 Dodge ram 1500 V8

[@TheSuburbanWarrior97]

does this fix heat to come out of the front vent aswell? no matter what it seems mines just blowing threw the vent

[@CMWeber88]

It should do the test at the window first

[@douglasloreman6663]

Wow! If this works, the time and effort will be reduced tenfold. Thank you!

[@CMWeber88]

Douglas Loreman no problem

[@dannyclark9820]

Hopefully you will see this. My 98 the air coming out of the dash will divert to the defrost when I go up a hill. Do you think this will fix it?

[@masonparks5909]

I have the same problem, under any acceleration it switches to the defrost

[@rayparks600]

Will this method just help to open the vents? My 99 dodge just blows through the defrost

[@CMWeber88]

Yes

[@robertmcfadden9748]

So was the vent door not opening? Because my vent door won't open and close?

[@CMWeber88]

Yea you can test it like I did to confirm that’s what was going on

[@chriskaloz881]

I’m not worried about my ac but how was ur heat with this line being messed up I have a 99 ram 1500 my line is completely missing my heat only blows warm when I’m in park an only threw the defrost vents

[@CMWeber88]

Never had a problem with the heater had the truck for 6-7 years

[@jomine16]

Which vac line did you cut behind the HVAC Controller?

The black one

Did that black hose that’s on your control switch there already or did u shove it in the outlet

@@josephtruskowski688 yes it was to the left my only had one black line coming out of it.

[@MichaelSmith-tg3mj]

Did you keep your defrost settings as well as having AC? Does the vacuum " fall out" under acceleration?

Michael Smith yea it always did that going up hill or 1/2 throttle

[@MichaelSmith-tg3mj]

@@CMWeber88 still does it? Or you fixed it?

[@CMWeber88]

Michael Smith it still did it as long as I had it I don’t own it no more.

[@MichaelSmith-tg3mj]

@@CMWeber88 sounds like what mine does without the extra steps. I've heard that the cruise control service has a leak there. It's under the battery and battery box.

[@MichaelSmith-tg3mj]

I've replaced the intake gaskets. I suspect it's a vacuum check valve or the afformentioned bad vacuum line going to the cruise control service.

[@johnsiira9478]

what part of the firewall the does the original line run through?

[@MrCarlosj0]

It goes through where the accumulator feeds into the firewall from outside passenger side.

[@MrCarlosj0]

Black piping at 1:13 mark.

[@tristenoberlender9685]

Does this work for cruise control too?

[@CMWeber88]

Probably idk never tried it

[@BlackCatFever2011]

PCV is buzzzzin

[@albertmagee5173]

I have a 1999 ram I keep hearing a vent close at the bottom of the dash a it blows hot air what to do

[@knighthawk86855]

Yeah the vacuum line Chrysler uses isn't good for hot areas, so it dryrots cracks and falls apart, super bad design, what I call the firewall grommet, has multiple lines running through it, the lines inside the truck are fine, but once it goes through the firewall grommet they break right there so I'm just going to take the grommet out, and run all new lines through the grommet hole, but wow dodge what a fail.

[@jamesduffey4442]

You low on refrigerant. Your ac is cycling on and off too much and it should not do it that much and the condensate on the drier up on the firewall tells it all. Your a little low on refrigerant

[@jamesduffey4442]

My dodge condensates.like crazy when it's low on freon. I'm an hvac tech and I can tell you a handful of things that lead me to believe it's low just by your video
