Passat (B5) :: Ac Doesn't Blow Cold Air
Aug 30, 2011
My 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.

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??

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.

So, 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?

I 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?

I 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.

2 weeks ago my ac on my 2005 passat started working on and off, sometimes it would blow hot air and sometimes it would blow cold air. I took it to an independent shop (which we trust, they been working on our cars for a long time and never been ripped off...but first time I've taken a Volkswagen to them) and they just did an AC diagnostic test and re-filled the Freon, replaced the filter...it worked for 1 hour and went back to blowing hot air again, so I took it back and they said a valve stem was loose, causing the AC to work sometimes and not others, so they replaced that with a new one, my AC worked for 4 days...than on the 5th day it blew hot air again.. What could possibly be causing this??? It is stressing me out, especially since I need AC in hot Houston summer weather.

I've got a '06 passat. The a/c was working fine one day, and then the very next day it just stopped. the a/c light comes on when I push the button for it, but it won't blow cold air. I'm not sure if this is a common problem on passats or what's going on.

I'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.

My g/f's 98 Passat 1.8T has been pretty bad on being able to blow hot air inside, and now that its colder out its even worse.
Ever since she got the car, the coolant temp gauge is always at it's coldest, so I'm thinking its time for a greentop sensor. Her coolant right now is a lil low so, in the meantime, I'll be headed to the dealer to get both a new CTS and some G12.
Her fan does blow air, but could there be anything else wrong that would keep it from blowing hot air?

My 2005 Prius is having a problem with the AC. It will only blow cold air if the temp is set at MAX COLD. Any other temp setting and it will blow hot air. Really hot air. It makes no difference what the outside or inside temps are. Is there a simple fix for this? I can control the AC by setting it on Max Cold and changing the fan speed, but I would like for it to work on the auto setting the way it is supposed to.

I 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.

Sometimes 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.

I 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.

My 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.

The A/C hasn't been working for a month now, won't blow cold air. Took it to the shop and they put 1.5 pounds of freon in it. But it still won't blow cold. I'm taking a 1200 mile trip in it soon and the shop isn't an option. There's no leak as of now. What to do?

I have a 2007 Ford Freestyle and last summer the A/C would only blow cold air when you would accelerate. If you were idling like at a stoplight it would blow warm air. I bought one of those freon refill kits and added freon but it said I was already over pressurized. So now that winter has passed I bought an AC manifold gauge kit and emptied the system and tried starting over. When I add freon the low pressure side goes up way too much and the high pressure side doesnt go up enough. So the low pressure side is over the recommended pressure and the high side is under the recommended pressure. Do I need to replace the compressor or is it something else? (I can also hear the compressor kick in when I put on the A/C)

I just got a 96 Grand Am for second vehicle, but it won't blow any air (hot or cold), I checked fuses they all look good. I'm thinking possibly blower motor, but wanted to get some feedback before I start plugging away.

I took my car in for an oil change a few months ago when I was told the belt going to my a/c compressor was missing. It must have snapped off some time in the winter. I got the belt replaced and when I go to turn on the a/c I can hear it engage but the air that comes out is no colder than just having the vent on. A friend told me I just need to recharge the refrigerant.
