Ac not working

It's possible there's a water leak somewhere around the windshield. I would pull that blend door actuator out and see if it moves when you change the hot/cold knob first to make sure it's working, since you've come this far. It's only 3 bolts. If it's working okay and the door isn't stuck, you may have to get the A/C system checked. A bad expansion valve will limit the pressure on the A/C low side. It's a tricky part to diagnose. Pressure readings will have to be taken.

AL 514 ,appreciate what you do to help me and thank you for guide me in this repair.You are a good person and a good professional and the main part, a good teacher.

I want to wish you a very prosperos and a happy new year to you and you family.Thank's for help me.

No problem, glad to help. Any other issues just ask.. cheers

Climate button no respond when I change to cool air. what can I do to fix it?

Heater problem
2005 Dodge Stratus 6 cyl Two Wheel Drive

My heater blows hot air when driving but when stopped it cools down.

hi laura deluca, thank you for the donation, It sounds like, you dont have enough refrigerant in the system, try this, when your at your home, open the hood, look at the compressor, and have someone start the vehicle, at the center of the compressors pulley, there is a piece called the clutch, you probably cant really see the difference between the pulley and the clutch untill its running and cycling on and off, while looking at the clutch notice if the center of the pulley(the clutch) is still or moving, or is it a stop and go,stop and go, type of movement. also notice if the fan is running. and let me know

Thank you for replying. I'll check and get back to you. Should I check to see if I have enough coolant too?

I took the car to a mechanic to check the coolant and it was low. I had a radiator flush and now the heater blows hot air when idle. Thanks for the tip!

When I turn on the heat only one side will blow heat . The left side blows cold air as if the ax is still on

try pulling hvac fuse inside car for 60 seconds with key to see if actuator resets if not it may be the actuator for that side.

I have a dodge stratus 2003 with weird a/c problems. Bought it a year ago. The a/c started not working so I had the a/c recharge and inspected a year ago and it still had problems right after. The dash control unit was acting up and the a/c would only work when I pushed in on the control unit in the dash. We had that replaced and a/c worked for several days and then didn't work. When I took it in for the 3rd time they couldn't get the a/c to malfunction. I got it back and same afternoon it didn't work. Then it started working when engine was cold but stopped working in hot afternoons. When the compressor came on it would work but the compressor would not come on at hottest time of day. Went through the winter and took it back in spring. through winter compressor would not come on at all. Auto repair place thought they found the problem with a stuck pressure switch and replaced that and a/c worked good for a week. The next week on trip to L A a/c compressor would not come on again when we needed it going by bakersfield. When in LA did not work after two days compressor started working again, but on trip back up to northern calif. started blowing hot again so we left the a/c on and every 15 or 20 minites the compressor would come om for a few seconds and then would go off. As the air temperature cooled, the a/c worked better and better. What seems to be the problem? I am going crazy with this problem.

This sounds like the automatic compressor controller is going out which is common here are diagrams to help you change the unit out. But to be sure here is a guide to help check the wiring and a guide to give you step by step instructions.

I wish I cam across the is post earlier because I just paid a shop to fix the same thing for $480.00 the part cost $89.00 ! DOH

The ac has stopped blowing cold when on max a/c. the compressor seems to cycle fast, and the condenser has frozen up a time or two. what should i do?

Hi:
If the compressor is cycling fast, chances are you are low on freon. I would have that checked.

still has freon.
at the auto parts store, they tried to sell me a cabin air filter. could that have something to do with it? is there such a thing?

heres a link,check it out,hope it helps www.aa1car.com/library/ac98.htm

The cabin air filter has nothing to do with the AC.

Air Conditioning problem
2004 Dodge Stratus 4 cyl Two Wheel Drive Automatic

Ac is out. Burnt up belt on the a/c compressor with clutch. The clutch is attached to the compressor. It was bright red, hot, and broke the belt. Bpought new belt and a/c compressor with clutch. Now on the new ac compressor with clutch, the clutch is constantly on, running and is smoking. Trying to ad freeon, it is trying (and did) die. Checked the fuses, not that. The clutch is getting hot still. What is causing this?

Check the low pressure switch, it's on the low pressure line, At compressor, If out of R134a, and compressor can run, switch is defective. This will overheat the compressor, no oil running through it!

DIAGNOSIS AND TESTING - A/C EXPANSION VALVE The expansion valve is located on the engine side of the dash panel, near the right shock tower. The expansion valve can fail in three different positions (open, closed or restricted). In an Open Position: this will result in a noisy compressor or no cooling. The cause can be a broken spring, broken ball or excessive moisture in the A/C system. If the spring or ball are found to be defective, replace the expansion valve. If excessive moisture is found in the A/C system, recycle the refrigerant. In a Closed Position: There will be low suction pressure and no cooling. This may be caused by a failed power dome or excessive moisture in the A/C system. If the power dome on the expansion valve is found to be defective replace the expansion valve. If excessive moisture is found recycle the refrigerant. A Restricted Orifice: There will be low suction pressure and no cooling. This may be caused by debris in the refrigerant system. If debris is believed to be the cause, recycle the refrigerant and replace the expansion valve and receiver/drier.

heater doesn't blow hot air at an idle. only when foot is on the gas and rpm about 1500 or higher. All vacum hoses are connected can't find and air leak anywhere. wHAT IS IT?

Check coolant level first to ensure there is enough coolant in system.


Thanks for using 2carpros.com!

I have a 2004 Dodge Stratus R/Tl with about 61000 miles on it. I have not had any problems except that all of a sudden the air conditioner stopped working. It blows out hot air only. I have had two people look at and one work on it. The first guy said that there was a hole in either the refrigerant or liquid line and no freon and quoted me at about $900 to fix. The second guy ran the dye thru and said that he could not detect any holes at alll and that the pressure was where it should be. He put freon in it and checked it periodically throughout the day and the air got as low as 59 degrees. That lasted about 2 days and it started blowing out hot air again. Nobody seems to be able to find anything else wrong with it. What else could it be? Also, just this last day when I started my car in the morning it made a coughing sound when I started it but then was normal. The weather has gotten cooler as low as high 40s could this be the problem? Thanks!

HI there,

Thank you for the donation,

If the second mechanic could not find a leak, why did he have to re gas the system? well i think that if the system was low and he could not see any evidence of a leak with the dye, there may be a small leak at the evaporator, (this is hidden under the dash and you can't see it) you may have to get an electronic gas sniffer test in the vent as if the evaporator is leaking this will pick up refrigerant in the vents, try this next.

First, the person who said their was a leak and no Freon was in the system seems to be wrong. If the system was working for 2 days, there has to be freon. Could their be a leak? Yes, there could. If you have the vehicle at the shop, they should have a freon sensor that basically is like a dog sniffing out its prey. If freon is present (leak), the sensor indicates it. Also, that would tell the mechanic where the leak is located.

Has the person who had it working checked for leaks?

I had cold air while driving on the interstate, but when you slow down or stop it blows heat. We bought an eighteen ounce can of refrigerant and put in it. now when you check the pressure it is in the blue and says it is charged. but, now it only blows heat. There are no leaks, you can hear the compressor kick in and out and collateral is full. What do I do ?

Hello,

It sounds like you have a compressor going out, you will need to connect a gauge set to see both high and low side readings.
