I have an 04 Supercrew FX4. The rear hvac is blowing little to know air. You can feel the temperature when you put your hand over it, but no air. Does the rear hvac have a seperate blower motor? Or possibly actuator problem?

 

It should have a seperate blower motor, go to mydirectparts.com and go to the hvac section and check the parts diagram

 

I don't think it has a seperate blower. I have an '07 and there might be enough air blowing to blow out a match. Different settings on the dash will make some difference but not much.

 

hey guys ..for some odd reason i checked mine today to see if it was blown air and on what seting on the dash ...well it did nothing i could a little from the floor but not much ...so are those vent in the rear for show or are they just broken

 

The only time my rear blows air is when a/c is on.

 

I checked mine today and they will blow out very little when on the vent and vent/floor setting. Put it on the floor setting and nothing. I didn't check the a/c setting as it was 18F this morning. It should work there though because it would blow out just like on vent setting.

 

yep, my rear vents always just worked in the vent or vent/floor settings only.

 

same here, my vents work, but then I always run auto mode. My boys haven't complained yet and it was 8 degrees yesterday!
