Ford Ranger / B-Series :: 2003 - Heater Vent Selector Stuck On Defrost
Dec 28, 2015
There is always something.... I just drove my girlfriend's new 2003 ranger edge home from the seller. Real nice truck. I noticed the heater selector doesn't change the air flow. It is on full blast for the defrosters, and is also trickling out of the floor and dash vents. No matter where you put the selector, thats the only place the air comes out.
The temp control seem to work OK, when you turn it on cold, you get cold air and visa versa. Even on AC and MAx AC... air out the defrosters. It's cold when you turn the temp control to cold.
I did some searching here and gather some info on checking the vac lines etc. Everything looks in place but one detail. The vac ball under the hood under the air box has 2 ports on the front end, and only one grey line going into it. The other port has what looks like a rubber boot and part of a very short vac line broken off it.
I looked, I cant find any loose vac lines. I'd like to know if this second port is suppose to have a second line on it, and where does it go? What color is it? Is this the reason the vent selector isnt working?

I have a 2004 F250 6.0 truck. My vent selector is stuck in the 'dash vent' position. I can't switch it to defrost, floor, or anything else. This past winter I noticed that heat would blow well but only through the dash vents. Now that summer is well underway I noticed that the AC blows through the dash vents also, but it doesn't blow very cold. I checked the freon, topped it off (didn't overfill), and still have the same issue. I checked the fuses and all are good also.
Of course, moving the selector to Max AC doesn't work either. Does this all point to the blend door motor? I hope not as the reading I have done means that this is one tough project to tackle.

, my trucks heat selector lever, that controls the temperature in my truck, is stuck in the cold setting. by stuck I mean, I can try to move it, but it wont budge more than about 1/16" and no more. its really frustrating because of the cold weather here, and I want to have SOME heat in my truck without a bonfire to get it.

I have a 2003 Jeep Grand Cherokee with about 240000 miles on the clock. Words cannot describe how impressed I am by this car. However, yesterday I noticed that the selector switch where one chooses to direct the air output has failed me. It seems to be stuck in the windshield defrost setting, unable to redirect the airflow to anywhere else. I am however still able to control the temperature as well as A/C settings. The switch felt strangely 'limp' almost as though it is no longer connected to whatever engineering or witchcraft it is attached to behind the control panel. What are your thoughts on this? Could it be as simple as some mechanical linkage that has snapped off? Just to recap: blower motor, heat and A/C are not affected by this.

Went to use my windshield defrost this morning on my way to work. everything went fine. Leaving work I selected the face vents with my AC on and it only blows hard from the windshield vent even though its already been depressed.

I have a problem with my vent selector on my truck. It's a 2005 f350 lariat. The vent is stuck on defrost, some times after a few mins I can get it to switch to floor but not always. I have replaced the pump, checked tank for cracks, disabled and plugged the auto hubs. The pump will shut off so I assume it's not a leak. I believe it's in the switching unit, can these be repaired? I found a lot of dust and dirt in the vac tank that had been sucked through a bad hub. I think it may need to be disassembled and cleaned. I have seen videos showing how to replace the orings in the older units. Are the newer style remote ones the same?

2000 Blazer LS 4X4. 186k miles. It would seem that my heater control will only work for defrost and face-vent operation. (Just happened yesterday) When I move the controller from the off position to defrost, I can hear the system moving the flaps into position. But it no longer moves for defrost/floor or just floor control. Would changing the heater control solve this problem, or could it be a bad vacuum line?

My buddy has a 97 Ranger 4X4 Automatic. The gear selector has become out of adjustment. To get the truck started you have to pull up on it (the gear selector) and it is getting worse by the drive. I think it is going to leave him stranded in the near future if it is not bought back in to adjustment.

My 99 Monte Carlo LS has a problem with the ac and the heater being stuck in the defrost mode. The heater and the ac work fine but it won't switch to anything else. I heard this could be a vacuum prob. I found a hose that runs from the top of the upper intake manifold. It goes to a T then one end to the firewall and the broken end is by the battery. I don't know where the broken end goes.

My 99' started o blow air only through the defrost vent today, and won't go through any of the other vents. I think this happens when your vacuum pump goes bad or there is a leak, correct? If so, how can I test these to figure out the problem.

2003 ford edge 3.0 V6 ... I was driving down interstate today going 70, set my cruise control & the button broke. My accelerator was stuck, when I would hit the brakes it would literally shake the whole truck. What happened & why?

So... p1451. Vent solenoid. I pulled the part and put 12v to it. Opens/closes just fine. Checked resistance on part, 55ohms like it should. Pulled vent canister, no apparent leaks or blockages. I traced wires back to cab. Cannot locate anybroken wiring. I looked up the pinpoint test on this dct and all thats left to test out is the pcm itself. Before I buy the obd2 scanner with all modes I wondering if I am missing something.
I did find a broken ground wire in my searching. Frame to body. My thoughts on a bad ground are that that would cause more than one monitor to register one fault code.

I have a 2002 Ford Ranger 3.0L truck that, all of a sudden, has a problem with the HVAC system that blows air only thru the defrost vents even when selecting any other vent levels (defrost, face/middle or floor levels).
I did find a thread on another forum regarding this problem, only it was for the 95-01 Ranger model years, yet they say that the 2002 Ranger is not the same as those earlier models.

I have a different issue than the typical heat on max ac. Mine is actually cold, it just sends all the air to the defrost vents when i apply the throttle. Comes back to the dash vents when I let off the gas.
I know that it's vacuum lines or solenoid, I just wanted to see if any guess on which specific line to check or any other info since I do NOT have a gauge to measure the vac lines for pressure.

Went to switch vent from dash to defrost and hear a clicking noise and also air doesn't come out defrost unless the air is switched to floor. Switch air to floor and it doesn't seem to change. Where is the blend door located. sound seems to come from center of the dash.

I just picked up another 2003 XLT and I'll be taking it in for inspection on Monday. Hoping it will pass easily, but there are a couple issues I'd like to address before going in there.
First and foremost, the heat/AC system is stuck in defrost. It will turn off when the selector is moved to the OFF position, but any other position just makes the air blow out the top of the dash. I did do some research on this beforehand (the seller made me aware of it) and I first looked at the actuator. When moving between positions, the actuator does not move at all. It does appear to be connected to the vent door's arm but there's no movement when going around the dial. I do hear what seems to be a relay kick on or off as I go through the different modes, but that's it. Does this point more towards a vacuum issue?
Second, and less significant...the self-dimming rear view mirror doesn't dim. It doesn't even power on. Where might the connection go for that mirror? Would be handy to have for night driving, but not that big of a deal if it's not functioning.
I'm also going to have to get the tailpipe mounted...seems it came off at some point and the seller asked me today if I wanted it. Uh...yeah, I'm gonna need that to pass inspection!
I am liking it so far. Runs well, rides well...I will be enjoying this one as well.

My wife's 99 Ranger's heater fan is not working. It was working off and on until now. The fuse is fine. I went out this morning and tested the blower motor for power in --had voltage. Assuming the motor was bad, I pulled it. Before wasting $ and a trip to town, I bench tested it --it works. Now my question: what do I do next?

I seen on this site awhile ago something about a fix for the heater control door, I have a 1996 Ranger and all I have is Hot heat and cannot cool it down with the temperature control.

Got a 2005 V6 Ranger with low mileage. Having a heater problem. We've replaced the thermostat, heater core, flushed the system twice, burped it to get the air out and replaced the hot water valve. The heater works for a few days then it goes cool: not cold. Adjusting "Temp" will make the temp decrease but it will not return to hot air?

My '04 Ranger has over 240k on the odometer. Runs great and has never given me any issues. Everything checks out OK - all the fluids, filters, and whatnot are in good shape. No CEL or any other indication that anything is wrong (except for maybe the IAC valve and clutch slave.)
I've noticed, though, that when I fire it up in the mornings to let it warm up while I scrape the ice and snow off the windows, the heat/defrost will not blow warm air. It doesn't matter how long I let it sit, it will only blow ambient air through the ducts.
When I get going down the road, however, the heat kicks in, after a bit, and works very well!
I've not found anything that would indicate an issue with the blend door or any other component and this is the first vehicle I've had that did this.
Is it normal for a 4.0 SOHC Ranger to do this? Or is there something I'm missing?... It's not really that big of a deal, but I do find it a bit odd that it would do this.
I mentioned the IAC above - I think it's "sticking" every once in a while and, when it does, I'll hear a loud "thump" right before it idles down to around 1k rpm. I can't see how this would affect the heat, though...

1997 2wd, 4.0 - As you can guess it runs pretty bad at idle. It has O2 heater circuit codes for all 3 sensors. I'm leaning towards the ECM because the 2 heater wires are both hot with the key on. I unplugged the computer and turned the key on and just one wire is hot. Looks like the ecm is supposed to ground the wire to turn the heater on, but it's going hot instead?
