Q: Aircond sometimes blows warm air on cold start but turns cold after a few minutes or once driven
I have a 2002 lexus LS430 where i had my cooling coil replaced 2 years ago due to a leak. Since then it was A cold. But recently, the aircond "somtimes" blows warm air on cold start but turns cold after a few minutes or once driven. What seems to be the problem and what should be repaired or replaced if necessary?
