Was having the same problem with just air coming out the defrosters . Figured I'd be having to tear the dash apart to find the problem, but then I watched your video and found that when I changed the fuel filter I must have knocked the line off . Thank you for posting this and saving me the aggravation !!

After replacing a variety of ac components, I took my truck to an auto mechanic and he couldn't find the reason for the ac clutch not engaging. Been driving it for quite some time with the inside windows fogging over, not fun. So today, saw your video, replaced the short oem vac lines at the junction you pointed out (they were dry rotted) and was able to get ac clutch engagement and full heat with air movement from the defrost vents to the floor vents! Thanks so much for the tip!

The vacuum was exactly my problem. Not only old dry rotted leaking hoses but further along that hard plastic tubing manifold along the firewall it had separated and needed splicing together with some small diameter vacuum hose. Replacing the dry rot and rejoining of the manifold allowed vacuum build-up and regaining control of a/c output vents!

After searching video after video and dreading removing the Blend Door motor (huge job) I found your video and within 20 minutes the problem was solved finding a small 1/8" vacuum line under the hood broken. Patched it with a temporary rubber sleeve. Very thankful for your post!!!

With hindsight I should have checked vacuum lines first; however after fixing the same issue on my son's 2004 RAM with the HeaterTreater kit I bought the blend door kit for my 2001. After installing the HeaterTreater blend door connector I realized my mistake. Found this video and then immediately found a cracked vacuum line in the engine compartment about 3" from where the line entered the firewall near the AC lines. I was able to make the repair by sliding new vacuum hose over this small vacuum line.

The vacume line for the heater controls on this 99 dakota had been cut inside the engine compartment...i used a couple inches of rubber tubing to splice the line back together....the heat controls work now and there's heat now too...thanks brother..👍

On the second gen rams the hvac unit has doors that use a vacuum motor to position the door; the vacuum motor responsible for air coming out of the defroster vents all the time is the one mounted on the far left of the unit there are just 2 ways for it to fail, loss of vacuum or mechanically when a small plastic pin breaks off which is what happened in my case. The fix was easy, I drilled a hole in the door arm and put in a bolt and nut, it's fixed forever; at the far right side of the unit is the door for fresh air or recirc air. When the A/C is in max A/C mode the air is being recirced. As for temp control, it will control the blend door either with a mechanical cable or a stepping motor. Hope somebody finds this info helpful

That's crazy, I would have never thought of vacuum lines for something electrical, thank you for the post, I will check that out. I had already replaced the temperature control panel new about a year ago so I don't think it's out that soon and I also put in a new fan motor too at that same time so I know it can't be those things

My problem is that my ac blows fine, but when I am accelerating my ac will switch itself to coming out the defrost vents, until I am not accelerating and then it goes back to the top vents. I asked people and no one I know has a clue what to check.....driving me insane!
@timothyevans4323Ай бұрын
You have a vacuum leak. Check your vacuum tank for a leak. The vacuum tank builds and saves vacuum for when you have minimal vacuum under acceleration.

My 98 At a stop, the AC blows cold as it should When I take off- it stops blowing through the front and starts blowing up through the defrost vents Once I let off the gas I can hear a vent flap smack close and the AC air returns to blowing through the front vents H E L P ! ! ! !
