Hot air

[Silver Bullit]

My 2003 ram 3500 has been into the dealer 5 times in 3 months for my a/c. It seems to have a leak they cannot find. And even when they charge it up it will only work for about 15 minutes of driving then it beguins to blow hot again until you stop and go again. Although at idle, when fully charged the truck will produce cold air all day. But unfortuneately i drive my truck. Any idea's... Pleae help.

My truck had similar symptoms to your. I had it charged and still could only drive about 10-15 before the hot air would begin. I was able to generate cold air again by pressing the A/C (snowflake) button to shut it off, then wait a second or two and turn it back on. This would work for a few moree minutes anyways. I took it to the dealer and they replaced and relocated the fin sensor in the evaporator. This has so far seemed to fix my problems and others have reported the same results
