Prius (2004-09) :: 2008 - No Warm Air Coming From Upper Vents On Dash
Nov 28, 2015
My ex-wife has a 2008 Prius. When trying to get heat, either using Auto A/C or manual, the display panel shows that only the floor vents are open. However, forced air is flowing from the upper vents on the dash. The air from these vents is not warmed. It seems to be unheated outside air. It's unclear whether this is a new problem, since the owner doesn't know if this behavior has been there since she bought the car. She does report that the car has always taken a long time to get comfortable in winter.

Coming home from work tonight, Radio turned down, Air off/Heat off. Whats the sound coming from the dash around the radio/heater controls/ vents? Can't really explain the noise, but its like a boiling/clicking/scratching noise.

I have a 2008 Mazda 6 that has been a great car, but with it getting warmer, every time I use the AC the air coming through the vents starts warm then cools, then warms then cools. What is causing it to be so inconsistent? As far as I know the AC has never been recharged or serviced.

I recently installed an egr delete and ever since, my vents have been stuck to the upper dash no matter which setting I put on. The vent will push the air conditioning, regular air and heat all the same. I have checked the fuses and they are all good.

I have a little question, why doesn't there come any warm air out of these 2 red vents? i have a climatronic but its not on auto, and it doesn't blow air anymore from 20 Celsius +, it does blow cold air though? Is this normal? kinda annoying cause there's only warm air coming out of the white vents, and thats not ideal if i want to be warm quick in those harsh winter days .

I recently just purchased a 2012 Hyundai Accent GL used with 30000km. I drive the highway to work and I've noticed that even with the heat off (fans at 0) there seems to be warm air coming out of the vents. The engine temp shows it's normal, which is usually just 1 bar before half. What's going on here? Is something not working properly under the hood?

When I drive around I feel warm air coming from the vents.
Now keep in mind this is my first vw but speaking just from previous vehicles when you drive around and the air is set to cold even if the system off cool air makes it's way through the system from the outside because the fresh air vents are open and the car is in motion.
In my R warm air always makes its way through, but keep in mind if i turn the system on cold air will blow because of the a/c.

My car: 2008 Prius (base)
Here is the problem: All of a sudden the two middle vents in the dash stopped blowing. I have played with the settings - on, off, all the way hot, all the way cold - nothing from the two mid vents. The left and right vent blow with no problem. There is also cold air coming from the vent near the windshield - just the two middle dash vents are not functioning.
What I have done so far: I had it looked at by a mechanic who I trust. He said there is a small motor (he called it a servo motor) that controls that middle vents (open/close). He said that had gone bad. He manipulated it so that the air blows out of the vents now and said not to change any settings until I am ready to replace the part.

The right hand A/C vent on the driver's side dash is suddenly giving me no air at all. The other 3 in front blow cool air just fine. How to check this out? (I did just check out the cabin filter in case it had something to do with a block there). I don't know where to look. This is a new problem for my 2007 Prius.
The A/C for the rear passengers has always been very weak. Do others find this to be true also? I keep thinking that extending the air outlets under the seats somehow might work.

Today I have noticed that my windscreen won't defogged. Normally it will just takes 30-40 seconds for it to clear. It seems the air that blow to the windshield has blocked or it won't channelled the air to the windshield vents. I tried to feel the air at the windshield vents, but couldn't feel anything. The air seems to comes from the front and the legs only no matter what button/switched pressed. I think the air conditioning amplifier may be faulty. I am thinking of replace it. I have searched the internet, but so far I cannot see any tutorial how to replace it.

History: A few months back I had a leak repaired in my cooling system. I noticed the other night that my radiator was nearly empty again, so I've filled it back up, but haven't fixed it yet.
As summer is over, I no longer need my AC. However that caused me to notice that at its coolest setting, the vents are blowing warm air (maybe 15ยบ warmer than outside) and that seems high to me.
My immediate thought is that the heater control valve may be leaking/damaged/corroded.

I have a 08 F150 king ranch and have a couple of issues. There is a strange sound coming from the dash behind the gauges it sounds like a computer hard drive clicking and the heater seems to be stuck on will not even blow outside fresh air.

I have a 86 f250 with rebuilt 302, new radiator, new hoses and heater core. I know the cold to hot selector works to open the door. now the ac works great although my heat is not working properly. I can put the defroster on with heat and the blower in the engine compartment comes on like normal. Now the problem is that we i put it on heat the blower in the cab does not blow air through any vents. I just purchased this vehicle and not really sure how everything works.
Funny thing also when the ac is on i turn the blower on low and its really high then the high is really low (its like to switch is working backwards) not sure if that has anything to do with it. Then when I was looking in the engine compartment i noticed the wiring harness has a plug going to the blower, then one plug to what looks like a heat strip of some sort, then someone took two oranges wires and wire nutted together to get the engine compartment blower to work. So now I'm wondering if I am missing something there??? Here's a pic of the engine compartment.......

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.

My 2005 F150 has developed an intermittent high pitch electronic tone that seems to be coming from the dash. Sometimes it comes on for a few seconds. Sometimes for several minutes. It never varies in pitch. It will occur even if the radio and fans are turned off. It will also occur if the engine is off and the key is just in the accessory position.

The rear roof vents on my wife's GX470 only blows (non-cold) air, even though the rear controls are set for the coldest setting and the front is blowing ice cold. There are no error messages.
It's clear the rear is not working properly, yet there are no error messages.

The A/C on my 2004 Accord has started blowing warm air out of the 2 driver side vents, but still blows cold air out of the 2 passenger side vents. It also occasionally blows condensation out of the 2 cold passenger vents. When this same thing happened last summer, the condenser and compressor were replaced within 3 weeks of each other. It is less than a year later and the same problem is occurring. Even more odd; every once in a while the 2 driver side vents will blow cold for just a few minutes, then revert to blowing warm air. The car does not have dual climate controls.

I'm trying to remove the upper control arm on a 2004 F-150 2WD. I took the wheel off, and it looks like I can't get the bolts off that attach to the frame off without taking out the shock and "coil over"? Is this the case, or is there another way to do this?

I have to replace the upper control arm on my 05 f150 4x4. I've been looking around the site and didn't see anything. Is there directions posted anywhere on the procedure? or if the strut assembly has to be removed? If so do I have to compress the spring first?
