Hello, I have a 2007 Dodge Caliber and my air conditioning

Resolved Question:

Hello,

I have a 2007 Dodge Caliber and my air conditioning recently started acting up. I live in the Bahamas but will be in Ft. Lauderdale, Plantation area this weekend so would like to order it and have it sent to my hotel if possible.

What is happening is when I turn on my a/c on full blast it works for about 1 minute and then stops blowing air, if it is on the lower settings nothing comes out of the vents. Do you know what part I need to order and where I can order it from to have it shipped by Saturday? The air that comes out when it does blow is cool and my car is not overheating.

Thanks

The problem you describe sounds like an evaporator that is freezing up. Do you notice a large puddle of clear water (lager than normal) after you shut the car off?

 

Also does the blower fan stop working or can you hear it working and not air is coming out of the vents?

Customer: replied 5 years ago.
I haven't noticed any water under the car but to be honest I haven't looked for any either, and no once the air stops coming out of the vents I don't hear the blower anymore.
Expert:  Tom replied 5 years ago.

Ok, trying to see whether or not the airflow stopped because of a clogged evaporator or a blower motor that is not operating.

 

Does the blower motor stop working in any other settings and temperatures (heat, defrost, etc.)?

Customer: replied 5 years ago.

I can check, I would have to run out to the car to double check though it will take a minute, but where I am in the Bahamas and it is soo hot :-) the only thing I have been using is the a/c and the first time it started happening was this weekend so haven't used the heater or defrost.

 

I did notice though that sometimes when it is on full blast it will not stop blowing completely all the time - sometimes it will blow just a little bit almost like it is on the lower setting and when it does that it does make a funny noise, also when it does that if I do change it to the lower setting then at no air comes out of the vents.

Expert:  Tom replied 5 years ago.
Ok, try and see if there are certain speeds that it works and certain speeds that it doesn't.
Customer: replied 5 years ago.
Ok just finished checking and no the defrost doesn't blow either
Expert:  Tom replied 5 years ago.

I hate to send you back and forth outside to the car. You must have missed my last reply. I need to know if it blows at any speed regardless of what setting it is on. You can just put it on vent or heat, doesn't matter what temperature, and try and listen for each speed. The blower motor is located on the lower part of the passenger side of the dash below the glovebox.

 

Pay attention to the sound as well. See if it sounds like a growling noise or maybe even a basecal card in bicycle spokes.

Customer: replied 5 years ago.
Ok that I can answer without going outside - no it doesn't blow at any speed, it will only blow at the highest speed and even sometimes at that speed it doesn't always blow - it will start blowing and then fizzle down to a low blow, like if it was only set to the lowest speed and when I turn it to the lower speeds (any past 4 and the setting are 1 -4) it doesn't blow at all. It does make a funny noise kind of like the baseball card in the bicycle spokes when it is at the highest blower but not putting out the full blowing power. When I drop it to the lower speeds I don't hear any sound at all.
Expert:  Tom replied 5 years ago.

Ok, these cars have a history of getting leaves and debris stuck in them to where the motor can not turn and the card in spoke sound is the debris stuck in the box around the blower motor. The fix will be to remove the blower motor and get the debris out. The long term fix is to install a screen that will keep it from happening again. Your vehicle may be under warranty still, so the long term repair would be covered. For now you could remove the blower motor and clear out the debris to see if that fixes your problem. I will paste the service bulletin and directions below:
