I have a 2014 sonata gls with about 20K miles (have only owned it for about 3K miles) and have noticed that no matter what position the selector switch is in, the air only comes out of the defroster vents. None through floor vents, nor front vents... just the defroster. What i should check or do?
View 5 RepliesI have a 2012 Hyundai Sonata Limited. The rear defroster light on the dash does not light up. The rear window defroster DOES work, but the light does not light up. I took it to the Hyundai dealer and they ordered and replaced some module. They saw the light still did not light up. The service manager said she called other dealers and discovered that none of the 2012 Sonata rear defroster lights lit up, so concluded it was supposed to be that way.
View 4 RepliesNow that the weather has gotten very cold, I used the rear windshield defroster a couple of times this week. The smell that it emits is absolutely disgusting, I had to turn it off. The front defroster isn't much better. What could be causing it? Also the rear defroster, when working, defrosts the window in a "V" shape, meaning the center is clear but the sides and top/bottom are still frosted. I have a 2014 GLS.
View 21 RepliesIs it normal for the rear defroster to only defrost the middle of the window. The top and bottom don't defrost. Does this have to do with the antenna?
View 4 RepliesSo the other morning I drive the 140 miles out of town to work for the week. when I pull up to the job site the cooling fans were revving really really high! never heard this before. then it went back to normal after I opened the gate and parked my truck and shut it off. I'm driving maybe 5 miles tops to the job and back to the motel every day. however that is far enough that my heater should be warming up and it's not even coming close to warm. it blows cold air. and to compound that I'm not sure the cooling fans are even working. they don't appear to be. Is there a connection here?

Today im driving along in my 2000 X v-10 limited and had the AC blowing on high. All of a sudden it started to blow out the defroster vents, then back to the correct dash vents, then back and forth intermittently.....No vacuum leaks that I could find.. Is that controls what vent doors open to control air flow?

My heat only blows through the defroster. I was looking for my vacuum pump, but can't seem to find it. I find plenty of diesel threads where they show it, but mine isn't in the same location. I can actuate the diverter by hand and it will make the heat stop at the defroster and come out at your feet.
I have attached images of my rig.
Were to look for the vacuum pump? Any key spots to look for failed vacuum lines? What is this?
This is where most threads say the vacuum pump should be.
This switches from defrost to floor when operated manually.
I have a 2003 Excursion 7.3 2WD Limited and all of the sudden experienced a number of issues all at once.
1. Turn signals stopped flashing (hazards still flash)
2. Lost Rear back up sensors
3. Lost overhead trip computer
4. Lost Rear A/C - switch does nothing
5. Front A/C now only blows through the defroster vent
I've checked all the fuses and cant find any bad ones.
I replaced the multi-switch flasher and turn signals still dont work - only hazards.
Where I live we don't need or use AC very much but in the winter my wife likes to set the interior temp up to 72 degrees and we often need the defroster, especially on the windshield. I've wondered which uses more electric power from the battery to operate, AC or the heater/defroster? Also, does the AC come on automatically with the defroster, thus giving a double whammy to power use
View 19 RepliesHad the shift lever recall (clip) performed. Now the driver's seat heater won't turn off. I call the dealer back and they said that nothing they performed would have caused the issue. However, I don't trust the stealership.
View 4 RepliesDefroster/heater fans quit without warning. Heat continues to flow from vents but volume not enough to keep windows defrosted. All fuses fine.
View 2 RepliesI have a 1990 Mercedes 190E with kind of low miles for its age. Nice car, runs well. The problem is that the blower for the AC, heater, and defroster won't go on when it's cold or wet outside. Sometimes while I'm driving it will suddenly turn on. Sometimes if I restart the car it will go on; sometimes stays on, sometimes goes off after a bit. When it's dry and/or warm outside - no problem; on whenever I want, stays on, no problems. I have checked and replaced the fuses and I have had it at three different repair shops and they all insisted that it was the center console control that was causing the problem and now I have that whole unit replaced and it has not fixed the problem no matter what I tell the mechanic. I get it that it's an intermittent problem making it harder to identify ...
View 1 RepliesI have a 1996 Suzuki Swift. My defroster stopped working several weeks ago.
If I have the defroster and heater on at the same time, white vapor smoke comes from my vents. My heater works fine when I choose the vent option for it to blow directly on me but I can see and smell light blue smoke if I change the vent option to blow on my feet.
In addition a thin white film covers my windows while I'm driving whether I have the heater on or not (and there's a slight oil smell in the car if the heater is on - I do have an oil leak). The thin white film can be wiped from the windows easily at first but becomes more difficult to wipe after 30 minutes or so of driving. Once I turn the car off, the film disappears within 6-8 hours.
When I turn on the heat or defroster I hear this humming noise coming from the front of my touareg, is this normal? I have a 04 v8....
View 5 RepliesThe indicator lights stopped working on the switches and the dealer replaced a fuse and they worked again. Now they are out again and it seems like the heater on the drivers side is on the low setting for random intervals.

View 1 Repliesi am having some big difficulties with my car i own a 2002 Lincoln LS v-8, has about 118,000 miles on it. when i bought the car USED the heater or ac didn't blow at all we fixed that all it was a fuse. But know that it is winter time the thing is my cars heater blowsn out cold air. ive noticed some times heat blows a little from the passenger side but not the driver and then if it does get warm (my car) its takes for ever. Know i dont really have a problem with the defrost becaseu in the mornings my windows are defrosted after like 20min. ive been reading alot about DCCV and i want to think thats the problem but i really dont know.
View 2 RepliesWhen my car idles the heater blows cold air but as soon as i throtle it up or drive off it starts blowing warm air, just bought the car the only thing ive checked so far is the coolant level wich is fine.
View 2 RepliesI bought my prius IV brand new in December, and its my first one. One thing i've noticed that's different, but when I have my AC on auto (I've preferred using Auto since my last car..) I notice when its cold out, it only blows to my feet, then eventually maybe after driving for about 45 minutes or so it will eventually switch to feet and air. Is this normal? Why it goes to just feet only for so long?
View 2 RepliesI've noticed that my X in the winter does not seem to warm up as it should. I watch the temperature gauge and notice that it barely gets to the first mark in the operating zone of the gauge. The heater blows warm air but not hot. I think its the thermostat that needs replaced because in other vehicles I would see the temp gauge rise and then drop when the thermostat opened. I've flushed the radiator and changed the fluid and not difference. I did find the heater valve on the right side was unhooked from the vacuum line and plugged it back in but no change from that being connected. Anything else I should check?
View 5 RepliesI own a 2002 Grand AM GT. With the engine temperature reading around 200, and the heat set at maximum, frequently, for about a minute, I will get nothing but cold air. At maximum heat setting, on one day, there would be hot air. Yet, at another time the air output would be lukewarm.
