heater & air conditioner not working

Not enough info. Is the compressor for the A/C coming on? Is the blower motor working? Have you checked fuses?

well the a/c would not come on if the refrigerant was released or tube kinked and broken....the Heat would not work if the thermostat was stuck open~ the blower would be their common concern, so the blower is not working...should be the complaint~

If blower works, Pop out the climate control pannel and check for voltage at plug by fan switch. If there's voltage present, u may have a bad climate control unit

2010 F150 Lariat heat works fine. When in A/C mode A/C works fine on passenger side but drivers side vent blow hot air. Anybody have any ideas???

My ac/heater only blows out a bit air when fully blasted while driving. Is it my whole control panel is the problem? Cause it makes a sizzling sound when rederecting they control air?

Nothing works nothing comes on

If the AC works but it's not all coming out of the vents you need to replace the vacuum lines that are by the four wheel drive solenoid behind the battery

So on mine it blows great but no heat or AC I cant figure it out any suggestions?
