2005 Rear ac works, front always on heat

[dross93ranger]

As stated my front blows hot air no matter where the dial is turned while the rear ac and heat does work perfectly. I am trying to find the cause of this since I have a 1 year old and summer is coming on. Could it possibly be the heater control valve under the hood?

Yup or the actuator (electric motor) that controls the blend door

There is a small vacuum hose attached to it, when is that suppose to have vacuum? I can't feel any with my thumb no matter what position the knobs are in

Let me check how mine is

Thanks I really appreciate it.

Ok when heater is on there is NO vacuum. When a/c is on there IS vacuum.

So I would follow the vacuum hose check for cracks or maybe the vacuum solenoid is bad

Sweet! That's what I needed to know, now I just need to find out why I'm not getting vacuum and I would say my ac will be functional again.

Also there is a lever which I am guessing pulls in and out based on vacuum. I still have heat regardless if where I push it...Ill update in the morning since I am at work now.

Right on! I know how it is I have 2 little girls and every car I own has to have a good working ac and heater lol the vacuum lines are hard pipe plastic. So if u think its cracked just get regular vacuum line it will work just fine
