Hot Air only
 

My 2007 4.6L only blows hot air. Set on cool, vent only - hot air. Turn AC on, hot air. Coolant and new and clean. Checked charge on AC - full. I heard there is a heater control valve. Bought one - and can not find where it is! What would make this only blow hot air on any setting? If its heater control valve need a picture of where it is!

It's called a blend door actuator, IIRC. Should be youtube vids available on how to replace.

Is your compressor coming on? There’s a common relay under the hood that burns up after a while. $20-30 part if I remember correctly.

i’m with Postal... blend door because it’s doing the same with fresh air vent.

That was it. Would have never figured that out! Pain in the butt to get back there and replace but got it done and have cool air now. Thanks!

good deal...
