I have two problems. The first is when leaving my truck idling for say 5 minutes, the check engine light appears, the fuel light flashes and the fuel gague rises to full. The second problem is that the A/C will only blow cold air when the truck is moving. While the truck is idling the air seems very warm. Any comments or suggestions would be greatly appreciated. Thanks!!! Is your fan by your radiator working? > I have two problems.

No, I have been looking at the temp gauge, and it has stayed in a normal range. Thanks! No, I have been looking at the temp gauge, and it has stayed in a normal range. Thanks! Yup, the fan and the compresor are both working. >I have two problems.

Here is my story: My car when idling would blow warm air. I was told the a/c's capacity is reduced with lower rpms, so just figured cost of having a small car, and I would talk to a shop guy about possible problems later. With time, the warm air increased and I could hear the idle sounds change. After getting to a shop the refrig was low, and reduced the capacity of the cooling power. I had a tiny leak(throught a fill valve), with time the pressure reduced enough the compressor wouldn't stay engaged at low rpms, and cycled. At higher rpms its output kept a pressure switch happy and ran well. So........ I would have a friend/mechanic check if you have an a/c problem. How old is the truck? later, tom @ www.MedicalJobList.com >I have two problems.

SORRRY ment age as in mileage. later, tom @ www.MedicalJobList.com I have been looking for a A/C mechanic, the truck has @83,000 miles the last ten have been on a rebuilt engine. Thanks!
