Would the control on dash cause there to be no air coming out heater vents on floor. I can hear the blower very loudly in dash about in the middle air comes out dash vents and out defroster ducts. When you switch to heater you get blower noise but very little air coming out floor vents.is it the control or possibly a vacuum mother on a vent somewhere
View 3 RepliesI bought a 1998 Jeep Grand Cherokee Laredo about 3-4 months ago. One problem i have is that the heat wont switch from the floor. I've heard the motor that does this is called the mode actuator, which moves a flap to direct air to different ducts, etc. I've checked all vacuum line that i could see, nothing. It is quite hard to work on as everything is literally jammed under the dash. It is also quite dangerous as I cannot defrost my windshield in the winter. I get a tiny bit of heat up to the defroster, but not a lot. Heat works very well, but cannot switch from floor. Cant even hear the little hiss that you get on other cars when you switch. I just have the basic 3 knob fan speed, directional flow, and temp knobs, as well as an A/C button.
View 6 RepliesMy 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.
View 14 RepliesI 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....
Noticed a deodorized smell coming from dash vents when heater put on? After my 30k service I noticed the smell of deodorizer.
View 6 Replies2003 Honda Odyssey 150K+ miles... My wife called today and said she was smelling raw gas coming from the heater vents on the first cold day this year. I thought we had this issue last year but not 100%. What it could be or how to fix it?
View 8 RepliesMy car had the smell of antifreeze coming from the vents, but it goes away when I use the "recirculating" button. Do u think it's the heater core? I hope not though. Also how much is the coolant suppose to be filled up too? Mine filled up a lot more then half the reservoir.
View 2 RepliesI have an extreme burning smell coming from my heater whenever it is on, curious I put the fan on cold and it still has the burning smell. I pulled over and got out of the car he popped the hood and I don't smell anything underneath the hood. I've been leaving it off because I don't want anything blowup on me... It is a 98 chrysler sebring convertible, and the low and medium don't work on it, it only turns on on high....

View 14 Repliesi have a dodge Dakota and there is water that leaks into the front right passenger side when I run the AC...
View 3 RepliesI have a 1998 Dodge Dakota in very good shape. I bought it from my brother who has owned it since 2000. I drove the truck from Reno, NV to southeast Alaska where I live, and all along the pacific coast. It rained a LOT and I noticed pooling of water on the floor at my feet, soaking the carpet completely and pooling up. I thought I was tracking water in the truck from my boots. BUt I have had it here in Alaska for 7 months now, and it is still HORRIBLE! It rains here all the time and I can't get rid of the puddles. There are no plugs in the floor for drainage and I can't figure out where it is coming in. The windshield looks good, and the door seals look good also. I cannot figure out where the water is getting in so I can stop it. THe truck is going to rot and rust if I can't fix it! And here's the thing, the water is pooling on BOTH sides of the floor-passenger and driver. I am baffled. No one ever sits on the passenger side so its not coming from boots! there is no way for water to flow from one side of the floor to the other.

View 5 RepliesI purchased a 2002 Dakota and have had a hard time ridding it. I thought that the heater core was leaking and getting the passenger side floor wet, but it's the overflow for the evaporator under the dash. The drain must be plugged. Will I have to remove the dash to pull the heater unit down far enough to clean it. I don't think I can do much from under the hood...too tight.
View 4 RepliesI have a couple of concerns:
1. On my temp control when I select the floor for the air it never comes out of the floor vents. Just curious before I tear into it.
2. When I run my AC it seems to alternate from defrost vents to head panel vents. Just wondering if that is part of its function or is there something wrong.
Have a 02 with climatronic. You put it on vent and it blows out the vent. You press floor and it goes ape and the fan goes to max and nothing comes out the vents and nothing comes out the floor. IF you put it on floor only there is flow like normal. You can not have it on floor and vent. I drove 2 other passats and they both allow floor and vent. Havent been able to check codes because car has been at dealer for a week.
View 8 RepliesI have a 98 gtp 2 door with the electronic dual zone climate control. I can't get air to blow much out of the floor vents. I applied vacuum directly to the actuator and air came from the vents fine. It seems there is a box behind the glove box that controls the vacuum to each actuator. My question is, would the issue likely be with that vacuum distribution box or with the electronic climate box itself.
View 2 RepliesI 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?
The town car will not switch its blower position from dash down to the vents or the floor. AC/Heat both work and the speed is still adjustable.
View 2 RepliesI have a 2010 f-150. Started having issues with the blend door actuator located behind the radio so replaced that a couple months ago and fixed issue. Now the a/c will only blow through the defrost and floor vents. I replaced the lower blend door actuator thinking that might be the culprit, but did not fix the problem. What the solution might be.
View 3 RepliesI have this issue on my 07 F350 TD. The vents were working fine, then from one day to the other the following started happening. No matter which blower setting I select, air only comes out of the defogger vents on top of the dash. The forward and floor vents do not operate. Cold and warm settings work, along with all blower speeds.
Found this, but need a little more to fix it:
Problem: Air flow has defaulted to the defrost vents (either all the time or under acceleration).
Solution: The system is designed to default to the defroster in the event airflow control is lost. Intake manifold vacuum is supplied to the control head, whether manual or automatic (electronic) to operate the vacuum motors.. A very common failure is a split, cracked, or otherwise leaking vacuum line located between the battery and firewall. Other causes include a leaking vacuum reservoir (inside the right front fender), faulty check-valve inside the dash, or other vacuum leak in the system.
