A/C Not Working Properly!!!
I have a 1999 Dodge Ram Van 1500 with a V-6. The A/C is ice cold at times and other times only cool. I don't think it is a low Freon problem. All input greatly appreciated. Thanks~~~Ron

Well the truck is 10 years old and from your username, I will assume that you live in Florida. It is probably the compressor.
Does the A/C work great while you are driving and have the RPM's up over 1500 then while at idle sitting at a red light or something along that nature, it blows cool for a minute then gradually gets warmer until it is blowing pretty much outside temp air. If so, this is the compressor.
When was the last time that you had the A/C serviced, if ever?
Granted this is going to be an expensive repair if it is the compressor, but if you want to check to see if there is low refrigerant, you can pick up charge canisters with gauges at Pep Boys or Advanced Auto for around $30 (sometimes less). They are real easy to use, you just hook up to the low side connector (it is a quick connect, so it is idiot proof there), make sure the car is on and the a/c is on full blast. Check the gauge while at idle. Then just look at the gauge and see if it is in the green. If the gauge is on the low side, then you will have to add refrigerant. Just press the button for a few seconds, let off and check the gauge again. Continue until the reading is in the green. Drive it for awhile and if it starts blowing warm a day or three down the road then you have a leak and will need to take it somewhere to have the leak found and fixed. It could fall anywhere from an O Ring to the compressor.
Now if the gauge reads on the high side when you first hook it up, have someone get in the car and run the RPM's up to about 2500. If the gauge drops to the green area and starts blowing cool, then this is the compressor and it will need to be replaced.\
Hope this help.

I'll get a gauge kit from a local parts store and check it out. Thank you for your fast response.~~~~~Ron
