I have a 94 ford Taurus all of a sudden my ac doesn't blow cold and my heat doesn't blow hot. Also every now and again I hear a sound like an alarm clock coming from passenger side??
View 3 RepliesMy blower doesn't seem to blow very hard. I've been in other fords and the ac and heat blows great. Someone suggested that that I pull the fan motor and clean the blades.
View 4 RepliesI own a 2000 Nissan Frontier. Just recently while I was driving (in 15 degree icy conditions!) my heater, which was blowing on setting 2, stopping blowing air. I tried messing around with it, and found out that it won't blow any air on settings 1,2,or 3. It does, however, blow air on setting 4, but that is accompanied by a slight strange noise/vibrating of the dash. The coolant level looks fine and I haven't spotted any leaks anywhere that might indicate that it's the heating core. I thought it might be the resistor.
View 4 RepliesMy a/c is not blowing cold. I checked the system and I went to the a/c shop, they recharged the system. Compressor starts and then it becomes tricky. On other Passat I checked, all a/c pipes get cold right away and stay cold as long as the a/c works. On this vehicle, all pipes become cold for 1-2 seconds after starting a/c. Then pipes shown in red gradually get back to room temperature, while only blue section remains VERY cold.
Apparently, the limit between hot and cold is, on the left pipe, the valve that is used to recharge the system.
A few weeks ago, I bought a new condenser, compressor, evaporator, expansion valve, ac line for my 2010, 200000 mile Prius and had them installed by a dealership. They weren't too happy about my independent purchase of parts , but they did the job.. After a few days, there was no longer cold air. The dealership is 1000 miles from where I live. They are willing to start over again, for free, and see where the leak is but I can't travel to there for awhile, and, already the heat is oppressive in the middle of the day. I asked the local dealership if they would run a test of the system which will be a bit expensive, and they agreed. But, they cannot guarantee that the test will be conclusive. After almost 3000 dollars spent on this, I really do not know where to go from here.
View 15 RepliesSo, I purchased a 2004 Subaru forester at the in of 2013, from a private seller. When I turn on the a/c the air is warm, I thought maybe the refrigerant so low, so I check the level and it is good, the a/c compressor clutch engages, but warm air still comes out of the vents. I am asking what else could cause the a/c to blow warm air?
View 1 RepliesSo i just bought my lexus es350 2007 and I just realized that my driver's side doesn't blow cold air unlike the passenger's side i tried to google it and then i believe as i read on here its the blender door.
View 5 RepliesI have an 06 subaru forester with a little over 130k miles on it. The AC has now become intermittent and when running doesn't blow super cold air. I had it recharged but that didn't fix the problem. What happens is that it will run fine for like 15-20 minutes or if not hot. The clutch will start by attaching very firmly but then suddenly for no reason will disengage. It is not slipping the belt at all. I dont think that it is a matter of too much air gap because when it grabs it does so very firmly. Also when they were charging it i noticed that the for a moment it was kicking on and off rapidly and then he did something that looked as though he might have released some and it stayed more constant?
View 1 RepliesI have a 1999 Mercury Mountaineer with 315,000 miles and pleased to say it’s a great car. Although in recent years during hot days the A/C doesn't blow cold at lower speeds or in traffic. It didn't do this when it was new say 200,000 miles. I checked the coolant charge at it remains fine no leaks, I think at at some point my mechanic did a conversion to the new refrigerant R something. What can I do to keep the A/C blowing cold at lower rpms? I have to add that it will also start blowing warm while driving down the interstate as well.
View 6 RepliesI have a 2002 Ford Taurus. When we bought the car the heat worked fine. One day we went to turn the heat on and it would only blow out cool air. We replaced the thermostat and that did not work. The blower works fine it just doesn't blow any hot air out. Also, the driver side seat adjusting control went out. The seat will slide backwards and will raise the seat up and down, but when you try to slide the seat forward it just makes a funny sound. It was working fine and the other day I went to move my seat forward and it wouldn't go forward.
View 2 RepliesI'm at the end of my rope! My 2005 Ford Five Hundred Limited has a constant problem with the A/C system and overheating. In the last year I've replaced the compress, expansion valve, dryer FOUR times. They have replaced the condenser, blower motor, and added Freon, and checked for leaks. It will blow cold when running fast and then blow hot. They have replaced belts pulleys, They have replaced the thermostat, fans, coolant reservoir, hoses. and it still overheats. I've taken it to 4 difference mechanics including two dealerships. No one can seem to fix this problem.
View 9 RepliesSometimes when I hit the start button it takes a couple of minutes for the AC to start blowing air. I even tried stopping and shutting off and restarting but it still took a few minutes to start blowing. It doesn't do this all the time just every now and then.
View 4 RepliesI can't seem to get the engine temp to middle range on the marker, but yet my heater blows "to me" hot air. Even while sitting in idle for extended amounts of time I cannot get it to "operating" temperature. I would think if my thermostat was stuck open my heater would blow either cold or slightly warm air. I have the 5.4L engine with knn air filter and no cats.
View 14 RepliesSo the heater on my 2001 f150 will only blow through cold air. I thought that I may have a heater core clog so I back flushed it with water until it was coming through clean and unrestricted but that didn't solve the problem.
Now, some things to note are a potential coolant leak. I can't seem to find one but I filled up the antifreeze about two months ago and when I checked it the other day it was more or less empty. I've filled it up again and I will monitor it for the next couple of days.
Another thing to mention is that no matter what setting I have the heater on (ie 'panel' or 'defrost') I get cold air blowing at the passenger side's feet. Is this indicative of a hose leak or something?
Also worth noting is that the intake hose to the heater core gets hot after driving but the outtake stays cool. This is why I originally thought I had a core clog.
Should I be checking my blend door? If so how to I access it?
Here's what I have. 02 X 7.3L 4x4.
Heater will work fine. Then out of nowhere just blow cold. I can turn it off then back on it'll blow hot for 1 minute or 20 minutes. Then out of nowhere blow cold again. It doesn't matter if I'm highway driving or city driving.
I'm kinda thinking it may be the door in the duct that's just closing. I real don't know.
I have owned my 2008 Rx 400 h for just over two months now and at the risk of sounding dense, am I right in assuming that when you are coasting along without the engine running, the heater will start to blow cold air? Everything works fine until you lift your foot off the pedal. This is my first Lexus/Toyota and hybrid so I'm not totally au fait with how it should be working.
View 2 RepliesMy 99 grand cherokee's heater is broken - fan blows but only cold air. I've had two mechanics tell me its probably the blend doors and will be quite expensive to repair because it requires removal of dashboard. Looking for after market repair kit which allows for a DIY fix going through the glove box? Is this a good bet to try?
View 5 RepliesCannot figure out how to get the heated air to flow through the back via the rear vents. All I get is outside air. I cannot find anything about it in the manual. The dealer has no clue but is trying to find something on it. New 2009 Santa Fe Limited.
View 11 RepliesI took my 200000 mile Prius to a garage that is highly recommended and the mechanic stated that I need a new evaporator and expansion valve. He tested the car for a day. There was no time to do the fix so I arranged for a dealership that I trust to do the job. When they were ready to do the work, they detected no leak in the evaporator, but said that the compressor, expansion valve, and AC line needed replacement. (They showed me the leak in the compressor with special glasses.) After I called the first mechanic with the new info, he said that he could detect a leak nowhere, but, in the evaporator, and, at the expansion valve area. I am now stymied as to what I should do.
View 7 RepliesPush A/C button is always on green. The (air speed) 01234 button is also always on green. the Push button turns on and off orange whenever I click it.
Anyways, the AC doesn't blow any hot air... always just cold. I've adjusted the dial to red and have left it there for a long time... no hot air. Any trouble shooting I can do?

Problem 1: Now that is is finally getting below freezing and I am having to use my heat, and I have noticed that it will all of a sudden blow ice cold air. It does not matter if I am idle / accelerating / decelerating. I must provide a disclaimer... I have not had to use the heat in the car since I purchased it Certified Used from the dealer in South Florida. After moving back to where it actually gets cold I find this issue. I had my trusty mechanic look at it and he flushed the heater core. That is problem 1.
Problem 2: For about 6 months now my car has been doing this odd shaking routine. It happens probably every time I am out driving. When it starts to shake, I can prevent it from dying by revving the engine. It does not matter if I have just started the car, am sitting at idle or if I am driving down the road. No check engine light or malfunction indicator light has come on the entire time. It feels like the car just runs hard, not nice and smooth like it used to. I have brought my car in to the trusty mechanic three times now and he can not find any problems. I did notice this morning that while sitting idle at the stop light, my car had its little epileptic shake and then stopped and the RPM's dropped to 500.
Later when I arrived at my destination, while sitting at idle before getting out of the car, the RPM's were at 2000. I have routinely put in fuel injector cleaner additive when I fill up with gas... maybe once a month. I usually fill up with regular gas, but will occasionally fill up with premium. This whole situation is blowing my mind!
