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.
2003 f150 lariat FX4 5.4L ... The heater only blows on defrost, Which vacuum line controls this? is it the black one that runs through the fire wall? What else can I check to narrow the problem down? this truck has the push button/digital controls.
View 7 RepliesI have an 06 F-150, there is lots of heat but it only blows on defrost. Is this the blend door motor or is it something else?
View 6 RepliesI bought a used 99 f250 v10, i went to turn on the a/c today, and it only blows where the defrost is toward the window. it gets cold after awhile, but nothing out the vents, the heat either.
View 9 Replies2006 F250 with the dash controlled 4x4. I typically keep the front hubs locked on this truck. I have recently noticed that when shifting into 4x4 that the a/c or heat will switch from blowing out of the vents to blowing out of the defrosters. Any clues how to fix this?
View 1 RepliesWhen I turn the control to heat the AC compressor kicks in. If turned to vent it does not kick in. Was this just a design flaw.
View 3 RepliesThere used to be a audible pop in my stereo speaker when my heat would kick on. Now there is not. My heat did this last winter around the same time. I checked Fuses. The blower blows, but it just blows cold air. It could be a thermostat, or a clogged heater core. 1997 Ford Ranger 2.3L ...
View 2 RepliesMy 02 Mountaineer doesn't have any air flow volume out of the heat, defrost, or a/c vents. The temp will change from hot to cold and the air direction will also change from floor, dash, windshield, etc. The a/c recirculation door also seems to be working. The fan sounds as it is running very fast, just not putting out any volume. What should I look for?
View 3 RepliesSeems like the temp control on the dash isnt hooked up....with just the heat on...temp doesn't change....stays hot. if i turn the temp to the blue side its still hot. the AC on it blows hot air....Max AC its cool. AC compressor is working fine.
View 9 RepliesI 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.
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?
My wife got off work tonight and went to start up our 2001 Ranger XLT, it starts, but wont stay running unless she puts the gas pedal down, it is also blowing white smoke from the exhaust and she says it sounds like it is missing, sputters and dies when she takes foot of gas.
No previous symptoms, ran perfect this morning, no loss of power all day, no smoke no sputtering and no check engine light. Any clue as to what it is. I have heard head gasket and O2 sensor.
I have a 2007 Ranger with the 3.0L engine. It has about 70,000 miles on it, and generally runs just fine.
This morning, the A/C stopped cooling. It was working fine on my way home last night, and simply does not cool today. There is no water underneath the motor when the idling while parked, so the compressor is apparently either not working, or not running at all. The fan blows hard, and the heat works. Just no cooling.
What are the possible and most likely causes of this? How much will it likely cost to have fixed? Also, when I was looking underneath the truck today, I noticed that the differential seems to be leaking a little. Is that an expensive problem?
I'm headed north in a couple days to the frigid regions of the country and I little worried cause my blower fan is now completely non-functioning (no heat, no defrost ). It came on a couple times since I bought it recently, usually after hitting a bump and stayed on for a while, but now it hasn't come on at all in a while. I checked all the fuses, they all looked good.
View 16 RepliesI have no heat in the LS at no settings. The AC runs good but does not seem to be regulated as it blows cold at any temp setting. The fan responds to settings but i still get no heat even with the AC turned off. I would like to find a diagram that shows the locations of the bleed valves to start a coolant air bleed.
View 13 RepliesSo I did alot of electrical work on this truck but never had any problems with the brake lights, now they dont work and the fuse blows every time you pop one in.
View 1 RepliesMy aforementioned ranger does not seem to heat up. Unless it is 95 degrees in the shade.... I have movement in the dash meter. Some - it will come off of the bottom - to not quite the c - then immediately dive back to less than cold ( which I realize is not possible) - engine seems to run fine. Use 93 octane or it knocks like a diesel. 135 K - I changed the thermostat. Less movement on gauge now than Before. Coolant level is fine. I read something in another post about the blend door. But my engine temperature doesn't even seem to be getting warm so how would the blend door be effecting that? I am an electrician not a mechanic, however I do all my own mechanic in in self defense. Since I cannot afford mechanics.
View 9 RepliesI have a 85 Ranger with a 2.3L engine. I'm not getting any heat. The temperature gauge never moves off of C, except when stuck in stop & go traffic. Even then it doesn't come up much. I tried to fix this last year by putting in a new thermostat, but it didn't work.

View 5 RepliesThe air flow with ac and heat is low on my ford ranger. I can hear the blower change speeds, but on high, it barely comes out. The temp is fine and achanges from cold to hot like it should. i had the ac checked out by a shop that that does free checks - no problems with lines or compressor. I replaced the blower motor. The air changes from defrost to floor and all the positions fine, but the air flow out all the vents just isn't what it should be. It was working fine the first couple of days. I've read about the blend door motor, but I haven't read about people having this exact problem. I am almost to the point of bringing is to the dealer, but would rather fix it myself.
2007 Ford Ranger ... 6 cyl. 3.0 L ...
I have a 2002 Dodge Durango and the rear passenger air blows cold only - was fine last winter. Neither the passenger or the driver controls will get warm air to the rear via the overhead vents. Warm air comes out under the front seats to the rear only.
