Ford F-150 - 1997-2003 :: Max Heat Blowing Through Vents When Temp Set On Cold
2001 F150 5.4 4wd - AC not working but when I turn the temperature dial to the blue side and turn on the fan, super hot air comes out of the vents or wherever I direct the fan to blow (Floor, defrost, etc) I know it shouldn't blow ice cold especially since my AC doesn't work but.....shouldn't I feel a temp change coming from the vents when I move temp dial from the red area to the blue? It's max heat wherever I have it set.

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.

View 6 RepliesCivic - Honda :: 2003 - No Heat Coming From Vents Unless The Car Is Over 2000 RPM
2003 Civic, ~180,000 miles. Previously had overheat problems, replaced head gasket, timing belt, water pump, thermostat and hoses (+ a few other things) No longer over heating, but there is no heat coming from the vents unless the car is over 2,000 rpm. Hoses to the heater core are both warm/hot, so flow through heater core seems to be good. Also AC has same issue no cold air unless over 2,000 rpm. Is this the control to the blend door? Are they operated by vacuum and with a leak, need higher vacuum to operate?

I am having problems with the blower on my truck. I can feel the air coming from vents no matter what setting on it. I think it maybe the blower itself as it was working and just quit. Is there a fuse for the blower that I can check? And I have the V6 4.2L 2 wheel drive

Where the cabin air intake location is? I'm not talking about the air filter.
My 97 F150 has some sort of exhaust leak and it's coming into the cabin when the heat is on. I want to tape up the cabin air intake port but I don't know where it is. On later models, it's on the right passenger side near the cowl of the hood. Where is it on the 97?
F Series :: 5.4 2003 F150 Started Burning Coolant And Heat Coming On
I just bought 2003 king ranch with a 5.4 it started burning coolant and the heat was coming on then while the engine was at operating temp would blow cold air. Then the temp gauge would start to rise,once it got to the top the heat would start to come on and the temp gauge would then go down to normal.I started by changing the thermostat which didn't work.
Then i figured it was air in the system I kept burping the truck at idle but it never worked, it kept burping while driving all the coolant out that i put in back out finally i took that cap off the one that clicks when you tighten it and replaced it with a cap that tightens down all the way and doesn't click. Every morning I check the reservoir fill it up to the proper level and so far so good.
Ford F-150 - 1997-2003 :: Idle Started To Flux With AC On And Started To Spray Coolant Mix Through Vents
I have an 01 SuperCrew with the 4.6L and it's idling really rough. Last summer, the idle started to flux pretty bad with the a/c on and eventually, it started to spray coolant mix through the vents and I lost heating about the same time. So, local dealership changed out the heater core and that is working again.
Well...I still have the idle flux, it fluxes from between 400-1000rpm at idle with the a/c on, it's a constant flux....up/down/up/down/up/down. A/C off and the idle is rock-solid steady. Dealership has changed 4 ignition coils over the last couple of years along with an EGR or PCV (whatever it's called) valve as well, none of which was for the idle problem, but somewhat associated. Where I should be looking?
Ford A/C :: 1986 F250 - No Heat Coming Out Of Dash Vents?
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.......
Ford A/C :: 1978 F150 XLT - No Heat Coming Out Of Defrost Vents
I just picked up a 78 F150 Ranger XLT with a 351M in it this past friday. I am absolutely in LOVE with her. She is a great solid truck. One issue I am having though is that she blows hot air out the vents over the hump but nothing is coming out the top of the dash. I am guessing that i will have to take the dash off and clean out the box check the door etc. What did you do to rectify?

View 13 RepliesPassat (B7) :: No Heat Or Air Coming Out Of Vents
The other morning I started my car up and no heat or air would come out of my vents. The night before I had to drive through a blizzard and my car was completely packed with snow. The climate controls function normally, everything is lighting up when i select a button, but no air is coming out of the vents (rear defrost and seat warmers work fine). There is no sound of the blower starting when I turn the air on, hot or cold. I live in Northeast Ohio so we currently have several inches of snow and it's well below freezing outside. I live in an apartment so my car is outside 24/7 between being here and at work. I looked up a bunch of posts on here and other websites to try to figure it out. I ended up taking my cabin filter out and it is completely packed with snow. So i vacuumed out the snow that was left in the cabin filter housing as far as i could reach. I also unpacked as much snow as possible from wheel wells seeing as the HVAC vent goes to there, and the blower still doesn't work.
What I am guessing, which I could be completely wrong, is that the HVAC vent is completely packed with snow and it's not letting the blower turn. I guess my question is does that seem remotely possible or is it something else completely? My climate control doesn't work on the highest setting so I don't think its the relay I read about and my heater has been working fine with no noises or anything and I don't believe it would just go bad out of the blue.

View 4 Replies5 Series :: 1997 - No Heat From Vents At Idle
I've got a 1997 528i with 285,000 KMS...the radiator, water pump and thermostat have all been replaced (within the last 2 years). The temperature outside has dipped to -15 C and I am now experiencing a problem with the inside cabin vents not blowing hot air through the vents. The car warms ups and the temp needle pins to 12 o`clock without any problems.
The vents blow cold air at idle (with temp needle at 12 o`clock) and them warm air when driving the vehicle. I have checked coolant level-it`s o.k, the fan speed setting ( hi and low) work fine, and the wheel located at the middle of the dash vents can be adjusted fine ( red and blue)...I have tried turning off and on the unit, adjusted temp setting up and down and tried to turn the wheel slowly (blue to red) but still not giving off heat as it should.
Prius (Gen 1) :: 2002 - Air Not Coming Out Of Vents When Turn On Heat
The vents in my 2002 Prius are starting to become problematic. When I turn on the heat, the air is not coming out. When I hit the glove compartment, the air starts to come out, but it is very low and stops after a minute or two. I just want to know if the blower motor is dying, and how to replace it, if it is really the blower.

View 3 RepliesGmc - Envoyxl :: No Heat Or Air Conditioning Coming Out Of Overhead Vents
I have a 2003 GMC Envoy XL. There isn't any heat or air conditioning coming out of the overhead vents. My mechanic tells me it is a control head module. I would like to try and fix this myself. I don't know where this module is located on the vehicle. It seems I could just remove the defective one and replace it with a new part. Are these modules easy to find in part stores and how expensive is this part?
