5 Series :: 1997 - No Heat From Vents At Idle
Dec 10, 2013
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.

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.

About mid-October I noticed when it as real cold out and I had the heat running whenever I would come to a stop I noticed there is very little to no heat coming from the vents, despite the engine being warm and running at operating temps. At the time I was working for a shop and I asked one of the mechanics what the problem was. He said that it was the radiator not having enough coolant.
Turns out when we pulled the cap the coolant res, was just about bone dry. So we added in about a gallon or so of coolant with the truck running and sure enough at idle the heat was back.
Fast forward to the last couple of weeks and when I am sitting at idle again same thing happens. So somehow the engine is losing coolant. Its not ending up in the oil (no white on the dipstick) and there is not a coolant leak. As it sits there is 255,300 miles on the truck now. 1999 5.4L F150....

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?

I have a '06 2.0T Auto, and the first cold day since I purchased the car was a week ago (I live in North FL) and turned on the heat, to find out that little to no heat was getting let out, so I brought it to my local guy, and said that the thermostat was probably stuck open, so he replaced the thermostat and housing for a couple hoses , and tested out the heat just now (55 degrees out), have it on 80 degrees and full blast, and still nothing. Also, usually I hear the cooling fan kick on after I shut off the car for about 5-10 secs, but haven't heard it since its not 90+ out. Its in the 70s.

Having problem of not getting any heat from the vents of the car? The fan works and more than likely it isn't the Thermostat. The engine also heats up normally, it's just that the air the blows out of the vents does not get hot anymore and it's getting to be fall.

As said vibration at idle, as I slowly accelerate (in park) the vibration is worse at 1200 rpm, then keep slowly accelerating and at 1800 rpm completely goes away. Doesn't seem like a miss almost like a balance thing. Also when in gear and accelerating it doesn't seem to be there unless I just don't feel it when moving.

Recently I noticed that I still have hot air coming through the vents with the climate control system completely off. I can tell that the fan is off because it's not blowing through the vents but the vents are very hot.

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.

tried to set temp at 22c to 24c, outside temp was 18c, but no heat, nor warm air came out from the vent. cold air all the way (at least 30 minutes drive).
set it to 30c and higher, then I can feel the hot air.
i just found out from here the prius's heater performance is not good. but that bad?
is it normal or should i bring it back to toyota to look at it?

Snap, crackle and pop sound coming from the vents in the front and rear when the heat is on. It sounds like rice krispies with milk.

The heater fan runs fine. Cold air comes out of all the vents (defroster, floor, dash). There is plenty of coolant in the system, and my mechanic advises the engine is running at the correct temperature. The heater hoses at the firewall are warm/hot as if coolant is flowing through. Flushed the heater core (but that didn't fix the problem). My mechanic now wants to drill some holes in the duct work to see if there is a mouse nest or some other obstruction.

I noticed a few months ago I wasn't getting much heat from my 99 Passat. I had the cooling system flushed and checked. Still no heat even after having all this done. Not long afterwords I started noticing that sweet smell through the vents, but couldn't find any leaks. I checked the expansion tank and it seemed to be slightly low so I added some coolant just to top it off and there it was. Steam started rolling up from the drivers side where the coolant had dripped on the exhaust and that's when I found the leak. I took the screws out that hold the tank to the bracket and discovered the leak coming from a short tube that appears to connect to nothing leaking coolant. Now here's my question, is the tank suppose to have a hole in it ? I thought it was suppose to be pressurized. What I don't figure is why didn't the shop notice it when they were refilling the system.

I recently picked up a 2005 Prius with 129k miles that seems to be in gFor any codes.
With most cars this would usually point to a faulty thermostat but I'm not sure on a Prius. I checked the coolant level and it's fine. I don't hear any gurgling in the dash so I'm guessing there's no air in the system.

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.

I have a 1999 Dodge Durango SLT 5.2L (318) 4x4. My problem is that there is no air or heat coming from any of my vents. It started out where there was no air coming out on the lowest setting. Then a few days later, no air from the next highest setting. It then continued to where absolutely no air coming from any setting. I don't know where to even start looking.

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?

I have a 2011 BMW 328i and I get this sort of burnt chemical smell through the vents when the heat is on. It doesn't happen until I have been driving for 10-15 minutes. After that you get the smell on some low level all the time, but it seems to be briefly exacerbated by making a hard turn (i.e. a U-turn). You get a stronger whiff coming out of the turn and then it returns to baseline. I also smell it stronger when setting off in low gear (1st or 2nd) like from a stop sign. It happens whether the car has the air re-circulation on or not. It has been in for service twice and they can't find the problem. The car is a RWD manual transmission and only has 20k miles on it. I checked the fluid levels and as far as I can tell they don't seem low. I looked in the service history and a coolant leak was fixed at one point, near the thermostat - yet the car still exhibits the smell. In addition to the smell, it kind of irritates the back of my throat after a while.

I have an 06 Prius. I was driving my Prius today and I've noticed that my car has NO HOT AIR...
And this is Winter!! I was driving for about 20 mins and still...No Hot air...vents are blowing cold (cool) air.
I recently changed my condenser/radiator but I did NOT fill my condensor with the A/C gas yet. (could that be the problem?) But isn't the gas inside condenser is for A/C and not for the Hot air??
Any other stuff that I need to check to solve this problem?? (harness, fuse etc.?) It's cold outside and my car has NO HEAT!
