aircondition

[tinaanddale]

04 3500 4x4 4door . the aircondition blows on high for about a hour then the air coming out of the vent is little or like the fan was turned to low. I can still hear the the fan blowing high in the dashboard but little air is coming out of the vent. When the truck or the ac is turned off for a little while it workes fine for a while then same-o again. HELP-PLEASE.

Sounds like your A/C coils inside the dash are feezing up. There are other posts on here very similar to what you're experiencing. My advice would be to not run the A/C in recirc mode during humid weather. Also, keeping a window slightly cracked while using the A/C will sometimes help keep the humidity in the cab lower and reduce the potential for freezing up. Could be other things too, but these are easy ones to try first.
