2004 Honda Civic Si Question: a/c stops blowing cold

had system charged and when driving it stops blowing cold and blows cold for awhile. it will stop and start blowing cold while driving -
Answer 1
Thermosistor is bad, It blows cold for a few minutes then no more cold air for a few hours. -
Answer 2
I had a similar problem with my Civic Si. Turns out that the A/C system was a little undercharged. I had the system fully evacuated and fully recharged to the proper level and haven't had a problem since. Also be cautious. Over charging a R134a system can cause a similar problem as well. -
