06 Aerio AC not cold enough

[wildcat_pr]

I have a 06 Aerio 17K miles now. Since new, I feel that the ac is not cooling enough as my previous other cars. I went twice to the dealer and told me that everything is ok. Also told me that aerios don't cold more than that. Why they don't told me that before signing the papers.

I'm not convinced about it. As my little experience in electronics, i noticed that just when the temp begins to cool down the compressor disconnects. I really believe that the problem is at the factory preset cutoff temperature at the thermostat.

Do someone knows where is located the AC ecu or the thermostat variable resistor so i can adjust it my way?

Had somebody else had that problem?

I live in PR where temps rounds always over 90 degrees. If the compressor can stay on for at least a minute more between cyles, I will be the happiest man with my car.
