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.
View 13 RepliesThe 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 1 RepliesThe 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.

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.
View 4 RepliesI 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.
View 3 RepliesI 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?
View 2 RepliesI have a 2006 Azera Limited and I am not getting any heat coming out of the passenger side vents. It will blow cold air so I know the blower motor is working and pumping out cold air, and I am getting heat on the drivers side just fine. With the cold weather now settling into Ohio, I wanna jump on this issue before it becomes a bigger problem.
View 1 Replies2003 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?
View 8 RepliesI 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.......
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 3 RepliesMy 2001.5 Passat traditionally does not start easily when it is less than 6degrees outside. Today it was that cold..it started easily..but about 30 minutes into my drive to work..I realized it was a little smoky and exhaustish smelling in the car..once I realized it wasn't the car next to me..i realized if I turned off the heat..the smell went away..but at the stoplight..i could see smoke coming from under the hood..out the corner by the passenger/dashboard... Car has 80,000, recent oil change, what it is?
View 1 RepliesAbout 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 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 12 Repliestried 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?
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.
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!
I have had my Prius for a few weeks now and have noticed a very strong smell of petrol when I have the vents open to heat the car (without AC). It seems to only happen when the fan is on and vents open. What could cause this and should I be concerned?
View 19 RepliesI purchased a used 2007 prius last month. Back then, I noticed a faint smell that reminded me of a barn, horse along those lines. I didn't smell too often because the car still smelled of whatever dealer cleaned with. Now that "fragrance" has worn off, the "horse" odor is more intense. I notice that it smells more in the back seat.
This morning I smelled the vent, and it seems to be coming from there.I heard it was the battery duct battery insulators that accumulate a sticky substance that smells.
My bride reports a musty smell, possibly coming from the A/C vents, in her new v5. I've been away from home for six weeks and have not driven the car since we brought it home from the dealer on Sept 2. In years past we had a series of Ford Tauruses that had this problem. Apparently moisture from condensation builds up somewhere in the system and mold/mildew results. We used to have to spray Lysol into the HVAC air intake to alleviate the problem for a while.
View 19 RepliesI was driving today with no music on and noticed something strange. I heard something "roasting" in the backseat...and looks like the noise comes from the battery vents. It sounds more like "roasting" noise than fan noise. Do you know if the battery was overheating?
View 7 RepliesToday 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.
