1999 Chevy Silverado A/C light & recirculation light stays on while switch is off.
 

Why does the A/C recirculation & A/C light stay on when the switch is off? The A/C will get warm then I turn the switch off and the A/C light & recirculation light stays on. When the lights turn off I turn the A/C switch back on and it is cooling again. What would cause this to happen?

sounds like something may be amiss in your controller.
