Nothing will blow out from vents, with heat or AC. I checked the fuse under the hood and that had continuity, I checked the 7.5 fuse under the dash and that was fine. I also replaced the blower motor resistor and the blower motor with brand new ones. Also used a test light to make sure power was getting to the resistor and motor and that is all good.
2004 Honda Accord EX Sedan .....
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!
The A/C on my 2004 Accord has started blowing warm air out of the 2 driver side vents, but still blows cold air out of the 2 passenger side vents. It also occasionally blows condensation out of the 2 cold passenger vents. When this same thing happened last summer, the condenser and compressor were replaced within 3 weeks of each other. It is less than a year later and the same problem is occurring. Even more odd; every once in a while the 2 driver side vents will blow cold for just a few minutes, then revert to blowing warm air. The car does not have dual climate controls.
View 1 Replies2001 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.
View 6 RepliesThe 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.
View 3 RepliesMy problems in my ac begin last year around Summer. My ac was blowing hot and not cold and once it even blew some kind of smoke out of the vents. It only did that once and hasn't since. I went to good year and put some freon in the car. And it started to blow cold again and I was good for a while. Well I didn't need the cold air for the last few months till the heat started up again.

View 14 Replies2004 Honda Accord with 120k miles sounds like an old sewing machine when cold for a few minutes (less than 5). The exact sound is on a video on youtube: [URL..... Dealer said they can't find it. Car has been maintained well and all services have been done. I've heard a lot of guesses (all expensive) but no solutions. Dealer finally got tired of me asking about it and said to just ignore it (turn up the volume on the radio).

View 1 RepliesI have a 2008 F350 and there is nothing blowing out of the vents or defrost for AC or heat. It doesn't matter what fan speed is set. Would this indicate a blower motor? Where exactly is it located and how to change?
View 8 RepliesI recently moved from TX to MN and it's getting cold enough to need heat in my car. Well I've turned it on and nothing but cold air comes out. I've check my coolant level and it was getting close to low, so I added more and I've checked the fuses and they look good. So, what it could be or how i can fix it?
View 14 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 2 RepliesI have a Honda civic 2011. Sometimes my middle two ac vents is not blowing out any air at all ( but the sides somehow works very little ). The reason why I said sometimes is because it stopped working for a day then it would work again the following day. I don't know what's wrong with it. I called for an estimate and the guy tells me if he has to open up the dashboard to open up the vents it would cost in upwards of 800.
View 8 RepliesMy car is blowing cold air but no heat at all. I checked the codes and it's throwing a B1 1-3-1. It's also throwing a A7 1-2-2. a buddy of mine is a mechanic but not too familiar with Volvo's. But he said that he thinks the B1 1-3-1 Driver's side air duct short is the problem. Is this the problem and how do I fix it?
View 3 RepliesI have noticed in my 2009 Honda Accord that the temperature of the heated air coming out of the dash vents drops when I select "all dash" as opposed to "mix dash and floor." It's significant enough to notice as it blows on my hands. But the dealer says the difference is within 5 degrees, which is within specs, so they won't do anything.
I don't think I can measure it myself since I can't fully jam my thermometer in the dash vent, so any reading would be contaminated by ambient temperature.
I took my 2000 V6 Passat into the shop because my heater vents were blowing cold. They tested the system and told me the following:
The hoses leading to the heating core are warm, but no warm air is leaving the heater core, indicating that it's plugged up with corrosion. They testing the coolant fluid and found that the incorrect coolant had been put into the system and that the fluid was carrying an electrical charge that must be corroding the aluminum portions of the system. In addition, the engine temp sensor is kaput and never goes up.
They offered a garden hose flush the heating system for a few hundred bucks, but warned that it is only 50% successful. They recommend replacing the heating core.
I had my entire A/C unit converted to R-134 on my 93 F-250. This was the entire system done at a FORD dealership. I've got about 1000KM on it, mostly this past winter. I noticed a few weeks ago when i turned the A/C on that the air seemed to be only blowing air, like vent. It was not air conditioned. I ran it for 15 min or so before suddenly there was a blast of really cold air and it held strong until i turned the truck off.
I cannot reproduce the results again, however. I can tell that the compressor kicks in like before, meaning it seems to be working mechanically fine. The temp outside has been at or just above freezing. Would this have any effect on the A/C? Should I park this is a heated parade or something to test it? What to test/check prior to bringing to the dealership?
Problem: About 10 minutes after driving, the heat starts to blow out of the upper vents when the a/c is on automatic. The heat comes out even if the outdoor temperature is mild (55 – 70 degrees Fahrenheit) and the cabin temperature is warm, which heats up the SUV quickly making it very uncomfortable. Turning the a/c off tends to somewhat solve the problem some of the time, however, occasionally hot air creeps through the vents even with the a/c off. The a/c often makes a gurgling sound whether it is on or off. I noticed today (2/3/12) that the back vents are not affected by the problem, so the very warm air is only coming from the front upper vents.
View 1 RepliesI'm having the same issue as many others with the heat blowing cold air. I have read through the other post ad tried the blend door, actutator, vaccine lines, control ***, and both lines going in and out are hot to touch when warmed up. I am now lost!
