Ford A/C :: 2002 F150 - Climate Control - System Stopped Blowing Air - Sputtering Noise From Fans
Jan 16, 2010
Have a 2002 SC lariat with climate control. A few weeks ago, the system stopped blowing air. It seems the brains still work for temp control as I can adjust the temp and the natural flow air through the system will change temp.
I heard a sputtering noise from the fans a few weeks ago at about the time it quit. Is this because the servo motors for the fans quit or if it would be something from the controls?

There’s a problem with my climate-control system. When I turn the fan on, there is no air blowing through the outlets on the instrument-panel. (There is air blowing thru the 2 vents immediately above the floor, and some air blowing at the base of the windshield). This problem exists regardless of what speed I turn the fan on, and regardless of which climate-control setting I choose (or whether I turn on the A/C).
This problem WAS occurring on an intermittent basis, and seemed to develop in RESPONSE TO my turning the knob to “defrost.” Now, however, the problem seems to be permanent. I wonder whether the basic problem is with the round knob that controls the various climate-control settings, as this knob seems somewhat hard to turn.
I have a 2004 Buick Century sedan, with automatic transmission (4speed) w/overdrive, V-6 engine 3.1 L.

Is there anyway to adjust the cabin temperature while the fans are off? I like to drive with the vents open but want to adjust the temps up/down without having to turn on the fans.

My wife's 08 mountaineers heater has stopped working on every setting but high it has the dual climate control with rear heat and ac I've heard there's a control module behind the glove box. Is this true and how hard is it to replace?

So in the past week only on certain days I have lost my ability to change zones for where my nice refreshing cold air blows on me from. It only blows out of the defrost vents. I here a fluttering noise under the dash when this happens. Also under the hood where all the AC hoses and such are located I feel cold air coming from inside the black box just next to what looks like the blower fan assembly. I don't believe I should be feeling that.

I have a 2004 volkswagen jetta, and it has started overheating. At first my problem was the thermostat. After that was changed out the fans stopped working correctly. It kept blowing fuses in s180 slot.
I read somewhere in another post that this is due to the fact the resistor in the low speed fan go bad, and for your car's radiator fan to go from zero to high speed, causes the fuse to blow. Also I read that when the fans start up it draws the most current, and then after it's running the current is considerably less.
This is my solution, I went to napa, and got a circuit breaker for a car, and Yes, to my surprise they make them. I picked up several a 10amp, 15 amp, 20 amp, and a 30 amp. First, I tried the 30 amp circuit breaker and it didn't trip the circuit, but when I put a regular fuse in the slot, it did trip the circuit, when I did the fan test at the thermostat switch. Next, I put the 25 amp in there and neither did it trip the circuit. When I put the 10 amp in the s180 slot, it tripped the circuit, just as the regular 30 amp fuses do. So that confirmed that the amps that were being drawn from the fans were not enough to trip a 30 amp circuit breaker.
What I did next, is I took a 20 amp circuit breaker and put that in the s180 slot. Then I hooked up vag com on my laptop to check and see how it performed with the 20 amp circuit, and these are the results.
Car Temperature in celsius
at 111 degrees the gauge was moving past the halfway point
at 115 degrees the gauge was one notch past halfway going towards the red zone
at 120 degrees the gauge was two notches past halfway going towards the red zone
at 122 degrees the fans kicked on high speed for about 30 seconds, and knocked the
temperature down to 105 degrees.
In conclusion, if the high speed on the fans work, you don't have to take those out and go and buy an expensive new fan set. Just stick a 20 amp circuit breaker in the slot, and keep using the fans that you have.

My 2005 Ford F-150 Lariat 4x4 5.4l V8. the climate control system will not let me lower the fan speed or let me change the airflow direction. and my heated seats will not work as well.. i looked at the fuse it was good.. and un-plugged the battery for 3 minutes.

So I noticed my temp gauge was starting to rise when I was on the freeway. I figured my fans were out but I just opened my hood and both fans were spinning. When I turned the car off both fans turned off but the temp gauge was almost into the red.
In the morning I turned on my AC and only the passenger side fan was working.
So I am not really sure what my next diagnostic step should be. The engine was not radiating any heat so I am not sure that it is even actually running that hot. Could it possibly be the temperature gauge? If I got a vagcom would I be able to check the actual temperature from there?
I am also concerned on how to find out if the fans are running at both speeds at the appropriate times.
Not sure if this is related but my cruise control stopped working a few weeks ago also.

I bought a 2002 gti mk4 with about 127000 miles on it .I did not know the turbo fans were blown out , they were sitting in my down pipe next to my catalytic converter . So I replaced the turbo myself , and 2 hours later the fans fell out of the new turbo , what might be the problem ? why it keeps blowing.

Recently my Climate Control System on Gen 3 has been misbehaving. A few weeks ago, I could not get cold air out of the AC, and then just as quickly as it stopped working, it started working again. Then yesterday, I started noticing coolant temps on the Scan Gauge rising to 215 - 220 F, which seemed quite a bit higher than the 195 limit I had set for operating with grill blocking, so I turned on the Heater and brought it down to 195, and when I got home, I checked and the coolant level seems OK, and it was under pressure.

i have noticed ever since i got my 15 rx that on hot days when i get in, and start it up. there is a pretty long delay before the a/c starts blowing? kinda stinks when its hot out and the inside of the car is even hotter? all i know for sure is my 01, and 05`s used to come on almost instantly, so just curious if this is just the way its supposed to be on the 15.

I have a 05 Avalon XLS and I've just discovered an issue with my climate control. It's that time of year that things are warming up so we started using A/C and found that driver's side vents are blowing warm air while passenger side vents are blowing cold. I've tried varied temps and dual mode on and off as well as auto and manual control. Nothing makes a difference. I suspect some sort of thermostat for the driver's side, but I really have no clue.

On the way to work this morning my dash lights went out. At the same time, all my climate controls stopped working, as well as the wiper controls. The blinkers didn't work either. However, the radio and MFD were fine. The windows were frosting up fast (I live in Canada) but it's only a 15 min. drive to work so while trying to hold my breath, I was able to make it work OK. I called the dealership and they said to bring to the car right away. On the way to the dealership, the overhead console lights stayed lit and could not be shut off. When I got to the dealership and pulled my key out of the ignition the overhead console lights wouldn't shut off as well as the radio and my the lock doors/security arming on my key fob would not engage.
Later, on in the morning they said they think the problem is in a module possibly in the steering column. What is going on with my car?

There is an intermittent buzz coming from the center console of my 2010 Prius trim level 2. It seems to be coming from the climate control system. It lasts for about three seconds, and it sounds like a fan with a bad bearing or rubbing against something else.
The buzz occurs when starting the vehicle after it has been off for several hours, and intermittently while driving (maybe once every couple of days), and exactly one minute after powering off. It began occurring a few months ago.

I've got a 2004 Silverado 2500, crewcab, longbed with a 8100cc gas engine. The truck has 80,000 miles and is in great condition. There's just one little problem - the climate cntrol system will occassionally go to completely hot. When it started a couple years ago, it was weeks between occurences. Now it's about every day and can be multiple times a day. When the system goes to hot, the only way to get back to the proper setting is to turn off the ignition and then restart.
It was happening on both the driver and passenger sides, but the first attempt to repair this issue was to change the envirenmental control computer - now the heat only happens on the driver side. The passenger side remains as set.

So I just got a 2002 1.8t, everything was fine until the fans and ac stopped working. After poking around the forums a bit I changed the following:
1. Fan Control Module. Result: nothing
2. Radiator Cooling Fan Switch Temperature Sensor. Result: nothing.
all fan components have the correct voltage going to them. Fuse 16 for the AC clutch is not blown and has power going to it. The AC compressor has power going to it. The fuses on the battery box have power going to them specifically S180.
My question is what am I missing? is it possible that the fans themselves could be bad? car is not overheating, the after run coolant pump kicks on. But the AC clutch is not spinning nor are the fans. btw AC clutch is not seized up.

I have a 2000 yukon and the climate control stopped working. The defrost works just fine but the heater/ac stopped working nothing blows out from my vents when ac/heater setting is on. I checked all fuses and wires and everything is ok and connected. I just replaced my cd player and the next day climate control stopped working. I went back and checked the wireing of the cd player as well, everything is fine. Would i need a new climate control, or senser or is there a fuse on the heater itself.

I just noticed this the other day. The three climate control buttons on the right side of my steering wheel--fresh/recirc, front defrost, rear defrost--have stopped working.
The functions still work if I use the MFD display to control them. What this might be? Is there a separate fuse for these buttons?

2000 Honda Odyssey - from inside the van, we have a rattle sound that seems to come from the climate control system. Leaves have been cleaned out, rattle went away for 3-4 days then came back. Rattle is while system is on or off, warm or cold engine. Sound is like a hamster wheel or maybe boiling water.

Just bought a used 2007 Passat 3.6L with 29K on it. Great car so far. However, I am wondering about a sound that is coming from inside the dash area. Sometimes when I am at idle, especially just after starting the car, I can hear what sounds like movement within the dash. I'm thinking that it must be the climate control system moving louvers, etc? It isn't constant, and really not all that bothersome. My wife at first thought there was a mouse inside! Is this something that others have noticed? Should I bring it in for inspection?

I have an 08 f150. Doing an Alpine iva w203 head unit. The back of the factory radio has two harness plugs, one is bigger than the other. A third plug is the ant. which needs an adapter too....but the root question is...... The bigger of the two is the harness that adapts to plug into the new unit, what is the second OEM smaller plug for that has no spot to plug into the alpine unit? does it just sit there not plugged in now?
Is the second smaller plug for the steering wheel controls? is this where I connect the SWI-JACK adapter that allows the steering wheel controls from the truck to go to the radio? if so, where do i find a harness adapter to plug into this second OEM harness?
