2010 Toyota Tacoma a/c button malfunction & no cool air.
As I turn "ON" the heating and air system on/off & speed Dial to "ON"
position on any of the following setting "Low/ #/ #/ Hi, the air conditioner
on/off button light also comes on, yet no cool air is coming, while the
temperature dials is set on the "MAX A/C". I keep pushing down on the a/c
on/off button but it won't go off. When I turn the temperature dial to
heat,the air conditioner on/off button light go's off and the hot hair comes
out okay. Can some one please help me to diagnose the problem ?Thanks
