A/C not cold

Hi my name is Cody. I own an 05 Dodge Durango. I have recently been having some AC issues. At first, it just wasn't blowing hard enough or cold enough. So I took it to the local shop near me and they just put in freeon. A few days later my AC in just the front didn't turn on when I started the car. So I tried turning it off and back on and it didn't work. But the AC in the back was still blowing cold and strong. Then while I was driving it randomly came back on and was cold and strong. It did that a few more times. It would not turn on especially during the hottest parts of the day. But it would blow fine at night. I took it back to the shop and they said that when they did the first tests on it that the back AC cut off but the front one worked fine. They then put a dye in one of the hoses and said that it would help them find a leak. I took it back after a week to find the leak as they requested and they said they had no idea what was wrong with it because it was blowing fine when I took it. It now continues to cut off and on randomly. But if I am driving over about 30-40 mph it will blow cold. Not strong but cold. But when I start slowing down it starts cutting off. Today it cut off again in the front and the back continued to blow strong. So I just decided to turn it off completely. It still blew cold air when I drove over 30 mph while the AC was off. I am very confused and am running out of options. Please help.

Last summer I was towing my camper back from the beach. The A/C pump went out @ 97 deg. I got a pump, expantion block (front and rear), and filtter dryer from auto zone. The expantion block looked slightly different but I used it anyway. It got cold but must be building up head presure too much because it gets warm just sitting still in a parking lot, (still blowing and pump still ingaged). I put the original expantion block back on. Now it gets cold but when I come to a stop or start to coast to slow down, I get a very rapid loud purring thud. It sounds like its coming from the expantion block or right there on the fire wall. It goes out imidiatly when I turn off the A/C. I thought I might have put in too much freeon in so I let some out, only to have to put more back in to get it cool.

I do not remember right off hand how much I put in, but it was the recomended amount and I did not go over the 100+temp markfor the presure, and yes I did vacume it down for about 45min. Used the vacume that Auto zone has on there loan a tool program.

180 or so, I can't remember but I will check it again tonight.

I have an 04 durango, 44k miles V6, that has been trouble from day one. The newest problem is the a/c. Last year it started blowing hot air and making a grinding noise. Dealer replaced clutch and pulley. Worked fine until now. It will blow cold air as long as you are driving fast and its not too hot outside (mornings and evenings). Its making a rattling noise as well. We checked the freon levels and they are fine. The blowing pressure is fine. However, it hesitates to change from vents to defrost or floor. The a/c light will stay on for a couple seconds after you turn it off as well. It seems to be similar to the problem we had last year, but should the same parts be bad so soon?

When I turn the ignition off and remove the key from my 2004 Dodge Durango the engine continues to run for several seconds later. Now the engine light is on and my air conditioner doesnt work. Steers fine.

Any idea on why the A/C system works when the vehicle is in motion, and why it stops when at an idle. I stopped by my local auto parts store and puchased R134a with a gauge. On hookup the gauge started dancing around in the red at the end. Another thing that is noticeable is the clicking noise when the A/C is on. Once turned off the noise will stop. Could this be my compressor?

It is very fast, when driving down the road you really can't hear the clicks. But, as you come to a stop they are pretty loud. It almost seems like the noise is coming from the floor board of the passenger side. When I get to the stop I turn off the system then the clicking takes about two seconds to quit.

I had my son help me the other day; I was checking to see where the noise was coming from. I doesn't seem to be the compressor or the clutch.

Not that I have noticed.

My air conditioning only blows hot air in the front of the truck but it blows cold air in the back of the truck. What could be the problem under the dash board.

My Durango is my second vehicle. So when I do drive it, I need my babies to bee warm. I noticed the rear heat is not working. Its blowing cool air when you use either front or rear control. My husband dismantled the plastic panels in the back and saw that the knob would make the flaps flip. And obvious we are getting air. Im not sure how much air should be pushing through. Anyways, I would really appriciate some ideas to try. Specific part names and locations would be helpful for a do-it-yourselfer.

Thanks for you time, cheers.
