Got an issue with the a/c. Blows cold at idle while driving after about 10 min it starts blowing warm. About 1 min after stopping at idle it gets cold again. Just about everything has been replaced. The APADS keeps showing a green light. any thoughts on this, it's driving me crazy.
Sounds like it's freezing up. Likely not enough air flow across the evaporator or low freon. Have you pulled the seat to look at the evaporator? What are you seeing with the gauges? Have you considered getting rid of the apads?
The evaporator was replaced along with the apads the gauges at idle are normal. the only parts not replaced is the condenser and compressor
Does the clutch kick out? What are the gauges showing when it's warm? What pressure also, don't just say normal
Make sure you have max selected to ensure it is recycling inside air. If not it will be drawing in outside hot air all the time. Also make sure you have coolant shut off taps on the heater core lines and those taps are shut off.
All that has been done, the problem is, it blows cold at idle. Once you get up to speed it stops blowing cold, return to idle and gets cold again. Could adding PAG oil every time it is recharged have anything to do with it ? I thought you only put the compressor oil in the first time when replacing the compressor.
Re-read post #4. Need the gauge pressures when it blows both warm and cold. "I thought you only put the compressor oil in the first time when replacing the compressor." Compressors come with oil and there are some instructions where oil needs to be measured and some removed at replacement. Oil normally added when replacing a condensor or evaporator.
Ok, few things. 1-the compressor clutch may be faulty where it will not engage when fully hot due to engine heat that is only there when moving. 2-you are going to have to set up a test light when driving to see if the compressor is turning off due to the APADs killing power to it. (make sure you have power going through the freeze switch.) 3-you need to road test with a set of gauges installed to see what the pressures are when this happens to help diagnose. The whole system only uses about 10 oz of oil. How much you add depends on how much leaked out and how much is still in there. The problem with that, it is impossible to know. During top ups, how much are you adding? I only add oil based on how much was recovered when I refill a system.
I have the same issue. Its the compressor. The clutch is likely shot and the whole unit needs to be replaced sadly. Had the same sequince of events but in my case my condensor had a hole through it and im pretty sure it caused the clutch on the compressor to burn up since after new condensor oil ect. It still doesnt work.
