#258 of 315 A/C made a weird noise by chilidav Jul 11, 2009 (4:04 pm)
So I was driving around and my a/c made this weird clunk noise, or at least I think it must have been my a/c. Since the noise my a/c seems to not be working right. I got in today and put it on high and had it on max. The a/c sounded like it was working at max but I could barely feel the air. My checks go like this, turn on the a/c on low, seems to work. Move it to the next level and it seems to put out a little more air, it was this way all the way up, but doesn't seem to put out like it used to. Like I said the air is cold, and is coming out of the vents, but when it's on max it almost sounds like it's trying to come out of the defrost on the passenger side. Don't know if anyone has had this before and I thought I'd ask before I take it in to be looked at.

Replying to: chilidav (Jul 11, 2009 4:04 pm) You didn't say what year it was but, if you suddenly experienced a lack of air flow from the vents, you most likely broke your recirc door.    remove your glove box door and you will see an grid opening in the upper right hand corner. reach your fingers in there and see if you can feel the recirc door laying there . If so then it broke. You can remove your blower motor. It has 3 screws holding it. You can use a flat blade screw driver, or a T20 torx. reach your hand up inside and twist and pull the broken door out. Your air flow will be improved. That will get you by until you can take it into a shop or take the entire dashboard out to replace the recirc door housing.

Replying to: condor74 (Jul 12, 2009 8:04 pm) There is an aftermarket kit that will allow you to replace the door without removing the dash or paying big bucks to the dealer. The repair is well within the capability of DIYer's.

Replying to: condor74 (Jul 12, 2009 8:04 pm) A broken re-circ door is a common failure on the RAM. The actuator motor is a small DC motor that is geared too strong for the door and will break the plastic over time. When you pull the glove box fully open, you can see a grate in the upper right that is the intake for internal air. With the system set for external air source, you should be able to see/feel the re-circ door pressed against the inside of this grate. If it isn't there, it has likely broken off and is lying in the bottom of the box blocking air intake into the fan. The grate has little purpose and can simple be cut to remove the old door. There is an aftermarket replacement that is easy to install and will give full functionality with metal components that won't break again like the plastic.   The system is built to choose between either external or internal air, never both. With the door removed, both the external intake port and internal intake port will be open. At highway speeds, air will flow into the external intake vent and directly out of the internal intake vent...like having a window rolled down all the time at 70mph. You will feel a strong air flow coming in under the dash and this will kill any heating or AC efficiency. The door has to be replaced to get back to optimal performance.
#262 of 315 2001 Dodge Ram 1500 A/C Problem by revteebee Jul 15, 2009 (10:15 pm)
I am experiencing a problem with my A/C. I turn the a/c on and it blows cold and when i take off it blows cold. But when I slow down it makes a kind of clunk sound and starts blowing hot air. Sometimes it will start blowing cold again but i sometimes have to turn it off then back on. It also happens more the higher the fan setting. Also when i accelerate it stops blowing through the passengers vents and blows through the defrost vents. This happens whenever I press the gas to speed up. I have checked the freon level many times and don't know what else to do. Replies to this message: condor74 (Jul 17, 2009 5:03 pm)
#263 of 315 Recirc door by chilidav Jul 16, 2009 (10:57 pm)
Thanks for the info, I did find my door just laying there. Not too bad to remove either, just pushed it up and pulled it through the hole. I noticed that on the door, the side that is connected to make it move was broken. At least I have some air flow now. Does anyone have a link for the replacement kit? Thanks again.

Replying to: revteebee (Jul 15, 2009 10:15 pm) it sounds like the little plastic coupler that hooks the blend door to the blend door motor is broken.     What I usually do is remove the forward screw of the blend door motor and carefully pull it off and swing it out of the way pivoting on the other screw. It is difficult to remove the other screw due to how close it is to the floor. Once the blend motor is out of the way you can use a pair of needle nose pliers and pull the plastic coupler out. if it cracked replace it and reassemble.

Replying to: kstell (Jul 09, 2009 10:07 am) Funny thing to read the posts...I just went to pick up my 2006 Dodge Ram with 19, 600 miles on it from the dealer for a prior service department repair. It was in for the steering recall and the wipers and blinker defects so widely discussed. (the ones where you turn on the left, and the right blinks...)   I got in it to leave, put the A/C on, and heard the low rumbling ubstructed air sound and got very limited A/C from the vents. I left the truck right where they parked it, and went back in and gave them the keys and asked to have A/C repaired.   Three years old, 19,600 miles!!! Three year, 36,000 mile warranty. What was this? A used car?
