so i went on a small family trip in the dodge yesterday. the air did great until the outside temp got over 80 and then it was like it couldnt keep up. any ideas on this issue i have looked at the common things and have come up empty

 

What are the high and low side pressures?

 

ok well i dont have guages to check, so i had a local shop charge it and it didnt change a thing

 

If your airflow is a little low as well it sounds like a recirculating door that broke. It's a common problem and easy to fix if you are mechanically inclined.

Also you may want to have the shop that recharged your ac to check pressure. There's a possibility that the compressor is going bad. But like I said if it feels like you have less flow on full then it's most likely that recirc door

 

Does the compressor clutch engage?

 

Your a little low on freon. If your drivers side is cold and your pass side is not as cold put a shot of freon in it! These systems suck due to low air flow in traffic or city driving the condensor gets to hot causing a over pressure which makes the relief purge.
I put a slim line fan on the condensor to cool it down seemed to help the problem!

 

Could also be a stopped up orifice tube

 

With out knowing the pressures you are kinda shooting in the dark, I would get a guage set they will pay for them selves fast.

 

ok thanks guy for the ideas, now that im home for the weekend i can look into these problem areas, how and where can i locate the recirculation door? im assuming its behind the glove box...

 

I agree you mey need to replace your dryer too. I have heard its a good idea to do it every 2 or 3 years. then have a good vacume pulled and the correct ammount of R-134 put in. If yheres too much the system will not work right. And if you look under the passenger side dash you will see the fan assembly. 3 screws and a plug later it will fall out and you can see the door up in the hole.
