2006 King Ranch A/C
 

I got a 06 King Ranch and every so often the HVAC controls don't come on. I turn the truck off and it comes back on. It does not do it often, I would like to fix it before it gets worse. I was thinking a relay?????

Try cycling the headlights On/Off next time. It happens to me. Nothing I know of for a real solution. Maybe get another HVAC control unit.

Thanks man. I will try that next time it happens!
