Same problem on a 97 Ranger. The switch does not push it, just turns and has always worked that way. I can turn the system off, but any other setting turns the AC compressor on. 85,000 miles and just started doing this a couple of weeks ago.
Anybody have any ideas?
#17 of 25 1995 Ranger air only blows on windshield
May 28, 2009 (1:03 pm)
My '95 Ranger blows air only on the windshield no matter what position I select on the control head. Also, switching from A/C to Max shows no change in fan speed whereas it did before. A/C still works. I've looked at the vacuum lines I'm aware of under the hood and inside the truck and see none that are broken or damaged in any way.
I notice that when I turn the heat knob I do get heat and I can hear a motor of some kind and what I think is one of the doors move if that makes sense.
Anyone else have this problem or any suggestions on approach to find the cause?

Rangers of about this age have real problems with breaking a shaft in the air valve controls. It's a real tough problem to fix this. If the shaft breaks, the valve will not move. I think it might even require removal of the dash. And the valve costs quite a bit to replace because I think the whole housing has to be replaced.

In the last two weeks I am getting a small vibration. This happens in drive stopped with the brake on.
It seems to happen when the air compressor kicks on. Is this a sign of a bearing or the whole air compressor unit going.
Any other things I need to look at?

Well, if the vibration can only be felt with the compressor engaged, then yes it's probably a compressor bearing problem.
keep driving it until it get worse. Don't drive it until it get really worse or it could freeze up, etc. But if you are only feeling a pulse at idle, the compressor might last for quite a while like this.

I've got something similar happening. 95 Ranger 4x4. Air goes only through the defroster vents (to the windshield) Temp control has no effect, air is always HOT, nothing on the selector switch works except "off" which turns the fan off. (truck has AC but the switch does not activate it) Fan speed control still works, ie when it's "on" I can control it's speed.
To say it in a different way........ the temperature dial has no effect, it's stuck on HOT,
the mode selector switch provides an "off" only, no choice of where the air goes, always goes to the defroster. The fan speed selector still functions.
Seems to be something in the vacuum control. Any ideas of where to look?

I found the fix for my problem and maybe it will help with some of your problem. I talked with the service manager at the local Ford garage and he gave me some idea what to look at. I have a 4 cyl 2.3 Liter engine. Looking at the engine with the hood raised there's a pair of vacuum lines that run from a connection on the right rear of the engine toward the top, across the back of the engine and then toward the left front of the engine just under what I always use to call the distributor. They are enclosed in a protective sheath that is split along it's length. I looked at the plastic vacuum lines in the sheath and examined them carefully and found one that had a hole burned in it just at the place where the lines cross the back of the engine. I repaired the burned line and the system began to work again. Hope this helps you.

I've got a 6 cylinder engine but I'm sure the vacuum systems are similar. I will check vacuum lines in the engine compartment.

I don't know the symptoms, but a known problem with mid to late 90's Rangers Heat/AC systems - a plastic (isn't everything) shaft in the 'air box' inside breaks. This shaft controls one of the main air switching 'doors' in there. To get to it, extensive teardown is required, including pulling the dash. Then, the entire air box must be replaced.
There used to be some postings about some some patch jobs that could be tried. You might try to find other Ranger forums and look for this problem and associated solutions.
