I have a 99 Chrysler LHS. When you turn on the air conditioning it (might) blow cold for a few minutes then it will start blowing hot - really hot air. MOst of the time it just blows hot. Car is not overheating and the coolant is up to correct levels. The compressor is working and you can tell by feeling the evap line that it is cooling. Even checked the system with gages and the levels of 134 are correct. It just blows hot air all the time. Is there a switch or flap that is failing causing it to change from air to heat?
