Prius (Gen 2) :: No Air Comes Out Of Vents Whether On Low Med Or High - Fan Not Working Sometimes?
Nov 28, 2010
This has been happening every once in a while and it has me puzzled. Sometimes my fan dosen't work and no air comes out of the vents whether on low med or high. It like the fan is broke.I will leave it on any speed and not air will come out but usually within 5 minutes or so it will start working. It happens out of the blue and I cant seem to figure out why or what conditions make this happen. I am a car guy and do all my repairs but I have not ever had a car with a touch screen HVAC.

I'm a new owner of an 05 Toyota Prius. Im loving the car so far, however, i am having an issue with my high beams not working. After doing lots of research it looks like the high beams on the Prius comes from the same bulb, what controls the high beams is the reflector.
My low beams and all other lights are working fine. After removing my bumper and looking through all the wiring I have noticed that their are two plugs that are not attached to anything. The lights look brand new, so my thoughts are that this car had HID lights and they were then replaced to non-HID lights.
How to get the high beams working. I don't see any HID ballast anywhere, so converting it back to HID would be costly since i would need new headlight plus ballast and bulbs.
I tried looking for wiring diagrams but can seem to find any.

My high beam indicator in my dash is not working, I pulled the bulb and checked it and it is fine, so I did a voltage test and I am only getting 1.5 volts at the light terminals, I should be getting 12 volts. Is there a wiring diagram someone has so i can see if it is the dash display itself or that I could trace back to the switch to see if it is something in the headlight switch? or What it could possibly be. other than that, everything else works.

If we have the air on a medium or high setting (A/C or just vent air) and coming out of the middle vents (at your face in other words), then turn the car off with the fan speed on that medium to high setting, then turn the car on later, the air comes out of the defroster (windshield) instead, even though the middle (face) setting is selected.
I have to turn the air fan speed right down to the lowest setting, then the air switches to the vents (face), and I can then turn the fan speed back up again. Its like it has a weak flap or something in the dash that diverts the air around. Car is an 03 6.0l limited with the "climate control" (the buttons and digital display).

I have a 2007 Camry SE-V6 and recently noticed my heater is not working properly. The fan dial works fine and I can adjust the speed of the fan no problem. When I adjust from the defroster, to the feet, to the face etc.. I don't hear that noise I usually hear of the system opening or closing the appropriate vents in behind the dash - all I hear is the fan blower going - as though it's just blowing on my windshield but no air seems to be coming in any of the vents (ie. if I put the dial to the face and the fan speed on high, no air comes out the vents).
If I adjust the temperature, I can feel heat is there vs. cold but since no air is blowing out (all I hear is the blower fan going), I don't get any heat in the cabin. Is this a fuse problem or something more serious? I have about 70,000km so I'm out warranty of course....

I have a 2001 Honda Odyssey and no air blows out of the rear AC ceiling vents, however the AC does work and blows cold air out of the front dash vents. I set the control (in the front) to have AC in the rear, but no air in the back. I do hear a click when I move the front controls from low to medium to high (blue dots). What might be the issue?

My car is a 2003 Hyundai Elantra. When I turn on my air conditioner it does not turn on and the vents release a bad odor (not like the mildew smell that could come from there, I don't know how to describe it but it was making me sick). When I turn on my air conditioner I can hear a fan turn on but no air comes from the vents; but air does come out of the defrost vents only. The smell is not as strong as it was when this first started happening, but it is still there.

My windshield and side window defroster vents have not been working but every other air feature on the air system works fine. When I switch to the defroster, air just continues to come out of the front vents and not out of the defroster vent located on the top of the dash. I plan on going to dealership to have it checked out. I have looked through my hayne's book with no luck. One of my buddies said it could be a relay or something but I have not been able to find a relay specific to the defroster. Just wanted to get this sorted out because it takes longer than usual to defog/defrost my windows now without this feature working correctly.
I have a 2003 Honda Accord EX V-6 Coupe with dual climate control.

I turn it up on any fan speed, and set it on the floor setting, and nothing blows out the bottom vents. pretty much no air is getting to the bottom vents.
I do feel some air blowing out of the windshield defroster vents when I put it on the floor setting. seems like something is blocking it maybe?

I have a 1994 suburban1500 heater is not working in front or rear and in the front I have no control on the vents it only blows on the floor flashes if I try and change from floor to vents or defrost also blows air on floor while driving with the fan off so seems that the vent is stuck open the rear I have control on vent or floor just will not blow heat just outside temp air I had the same problem with a buick I had and never figured out the problem this is driving me crazy.

Car sat there for 2 days non driven. Started it up, turned on the AC and it wouldn't blow through the front vents no matter what "mode" I select whether its on vents or legs. Instead it only blows through the windshield ones for the windshield. And it is also blowing outside air or maybe hot air, regardless what temperature I select and with the "AC" button on.
Before when I would press the "AC" button while the air was running I can hear a compressor or some clicking sound which is normal but now there's no sound when I press that and no sound when "mode" is changed.
What I've tried:
All fuses, all are good.
AC relay (good).
Disconnect the battery for 10 min, reconnect. Nothing.
Repair manual suggested action where it displays some codes. (I failed to link those codes to a proper definition in the manual)
Its been 90+ degree here in CA. I cant drive this car without AC.

The middle heating vents on my 1999 Subaru Legacy sedan stopped working recently. The other vents (by the window, defroster and floor) work fine. What might be wrong and how to fix it? The car has nearly 170K miles and I need to keep it running.

Push A/C button is always on green. The (air speed) 01234 button is also always on green. the Push button turns on and off orange whenever I click it.
Anyways, the AC doesn't blow any hot air... always just cold. I've adjusted the dial to red and have left it there for a long time... no hot air. Any trouble shooting I can do?

My dad just got a 2012 Camry LE, with the 4 cylinder engine. The heater seems to be working fine except for the floor vents. When I select that option on the HVAC control, I can hear the fan working but there's absolutely no airflow coming out from under the dash.

I noticed a couple weeks ago after starting the truck and turning on the a/c that nothing was coming out of the vents. I found it odd when after driving a few miles the a/c kicked in and started blowing cold air. Today I needed to put on the defrost and same thing, nothing came out of the vents. I drove around for a while hoping it would kick in just like the a/c did but nothing. I did check the fuses and relay. When you turn the control either to heat or a/c you can hear a clicking sound under the hood. It's trying to engage but nothing is coming out of the vents.

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.

So I got in my truck yesterday and i started it like normal and turned air on. The air will not blow out of the vents but only the defrost vents. I have checked all vacuum lines and good, my 4x4 engages and no issue with it locking in. I am Puzzled on what it could be?
