'96 C280 ...A/C problem, help ...
 

Hi Guys,

My A/C has been working just fine and the other day I turned it one on AUTO and the two vents at the doors ( pasenger & drivers side ) would blow warm air and the center ones COLD AIR. When I turn off the AUTO set it to manual all vents blow COLD AIR. What is the problem ? Any valve is stuck ?
Please, help me. Any info would be greatly appreciate it.
