Hot air at floor while driving with A/C on!

[Fred.05TJ]

Guys, I have a 2005 TJ that blows hot air out thru the floor vents while driving with the AC on. I have checked the blend door actuator and the mode selector switch. Please help!

You have checked the blend door actuator...
Is the shaft actually turning the blend door or is the blend door not fully closing?
You need to do a further inspection.... this certainly sounds like the door isn't fully closing...

is the A/C blowing cold and normally through the dash vents?

Yes the shaft is turning. What would keep the door from closing?

Yes it is blowing cold through the vents.

Is it for sure coming from the floor vents? A torn shift boot can let a lot of hot air in too.

It's for sure coming from the two plastic vents that blow on the floor.

Damper spun slightly on shaft, air box insulation, dead mouse....

Hey Mr. Charles

How many blend door actuator motors are on the TJs?

IF you download the PDF of the FSM for your year TJ and look on pages 24-1 figure 1 and 24-2 figure 2 in the Heating and Air Conditioning section; there is one blend door actuator, two mode door actuators, and one recirculating door actuator.

Thanks! I see that now

I had a similar situation.
Air coming out locations didn't match what was being selected on the controls.
For me it turned out to be a bad vacuum selector switch.
I found it by mapping out the position of the various actuators in the various positions.
The all actuators were actuating, just not correctly vs what was selected.
(There is a vacuum circuits diagram in the field service manual that was helpful for what should be happening.)
New one from Amazon, and mine has been good ever since.
