Prius (Gen 3) :: Climate Control System - Could Not Get Cold Air Out Of AC
Aug 2, 2011
Recently my Climate Control System on Gen 3 has been misbehaving. A few weeks ago, I could not get cold air out of the AC, and then just as quickly as it stopped working, it started working again. Then yesterday, I started noticing coolant temps on the Scan Gauge rising to 215 - 220 F, which seemed quite a bit higher than the 195 limit I had set for operating with grill blocking, so I turned on the Heater and brought it down to 195, and when I got home, I checked and the coolant level seems OK, and it was under pressure.

There is an intermittent buzz coming from the center console of my 2010 Prius trim level 2. It seems to be coming from the climate control system. It lasts for about three seconds, and it sounds like a fan with a bad bearing or rubbing against something else.
The buzz occurs when starting the vehicle after it has been off for several hours, and intermittently while driving (maybe once every couple of days), and exactly one minute after powering off. It began occurring a few months ago.

Lately, in my 2004, with the climate control OFF, and recirculate setting OFF (outside air selection), I seem to still be getting cold air in thru the vents. The air flow selections are all working appropriately between defroster, feet, vent. When I select the OFF button, the fan stops but the last selected air flow stays highlighted - and the OFF button is still black (or, unselected).
QUESTION - I swear I remember the OFF button highlighting when turning the climate control OFF. Am I just imagining this or could it be the source of my air leak? Is your climate control OFF button highlighted when you turn your climate control off. I need a reality check.

Can I use the remote climate control switch to heat the cabin during cold mornings as well as cool the cabin during hot summer days?

I've got a 2004 Silverado 2500, crewcab, longbed with a 8100cc gas engine. The truck has 80,000 miles and is in great condition. There's just one little problem - the climate cntrol system will occassionally go to completely hot. When it started a couple years ago, it was weeks between occurences. Now it's about every day and can be multiple times a day. When the system goes to hot, the only way to get back to the proper setting is to turn off the ignition and then restart.
It was happening on both the driver and passenger sides, but the first attempt to repair this issue was to change the envirenmental control computer - now the heat only happens on the driver side. The passenger side remains as set.

So in the past week only on certain days I have lost my ability to change zones for where my nice refreshing cold air blows on me from. It only blows out of the defrost vents. I here a fluttering noise under the dash when this happens. Also under the hood where all the AC hoses and such are located I feel cold air coming from inside the black box just next to what looks like the blower fan assembly. I don't believe I should be feeling that.

2000 Honda Odyssey - from inside the van, we have a rattle sound that seems to come from the climate control system. Leaves have been cleaned out, rattle went away for 3-4 days then came back. Rattle is while system is on or off, warm or cold engine. Sound is like a hamster wheel or maybe boiling water.

Just bought a used 2007 Passat 3.6L with 29K on it. Great car so far. However, I am wondering about a sound that is coming from inside the dash area. Sometimes when I am at idle, especially just after starting the car, I can hear what sounds like movement within the dash. I'm thinking that it must be the climate control system moving louvers, etc? It isn't constant, and really not all that bothersome. My wife at first thought there was a mouse inside! Is this something that others have noticed? Should I bring it in for inspection?

There’s a problem with my climate-control system. When I turn the fan on, there is no air blowing through the outlets on the instrument-panel. (There is air blowing thru the 2 vents immediately above the floor, and some air blowing at the base of the windshield). This problem exists regardless of what speed I turn the fan on, and regardless of which climate-control setting I choose (or whether I turn on the A/C).
This problem WAS occurring on an intermittent basis, and seemed to develop in RESPONSE TO my turning the knob to “defrost.” Now, however, the problem seems to be permanent. I wonder whether the basic problem is with the round knob that controls the various climate-control settings, as this knob seems somewhat hard to turn.
I have a 2004 Buick Century sedan, with automatic transmission (4speed) w/overdrive, V-6 engine 3.1 L.

My 2005 Ford F-150 Lariat 4x4 5.4l V8. the climate control system will not let me lower the fan speed or let me change the airflow direction. and my heated seats will not work as well.. i looked at the fuse it was good.. and un-plugged the battery for 3 minutes.

Have a 2002 SC lariat with climate control. A few weeks ago, the system stopped blowing air. It seems the brains still work for temp control as I can adjust the temp and the natural flow air through the system will change temp.
I heard a sputtering noise from the fans a few weeks ago at about the time it quit. Is this because the servo motors for the fans quit or if it would be something from the controls?

My 2009 Sonata Limited always has the front window defroster come on in cooler temps when the climate control is set to AUTO. This is aggravating since it shouldn't do that. I took it in for service last year at this time and they didn't find anything wrong and I gave up arguing with the dealer about it.
Is there a sensor or something that is out of adjustment? It comes one when the temp is about 40F or lower and you just start the car after it's been sitting cold. I don't notice it so much when I am out on multiple errands.
Another thing that I notice is that I can never just turn the fans on for air circulation when the temps are moderate, not needing A/C or heat. If it turn the fan on, it always seems to blow cold air feeling like the A/C is on, even if it is not in AUTO mode. I complained about the same thing and the dealer said the unit is operating OK.

This might sound like a stupid question, but how should the climate control operate in cold weather when set to auto?
I have a 2011 screw, when its cold out, and I start the truck, cold air blows out of the front defroster when the climate control is set to auto.
The fan on my previous ford vehicles would not function till the engine reached operating temp. Then the fan would turn on and blow warm air to the lower vents.

I have a 2000 yukon and the climate control stopped working. The defrost works just fine but the heater/ac stopped working nothing blows out from my vents when ac/heater setting is on. I checked all fuses and wires and everything is ok and connected. I just replaced my cd player and the next day climate control stopped working. I went back and checked the wireing of the cd player as well, everything is fine. Would i need a new climate control, or senser or is there a fuse on the heater itself.

Last November I had a left front end collision with another car. The other driver was at fault and their insurance covered everything. The car was in the shop almost 2 months.
Now it seems back to normal except the climate control randomly shuts off every so often. I usually leave it on Auto. After the car has been off overnight or sometimes just a few hours, I notice the climate control is off. After turning it back on, the temperature setting has been reset to 75. It happens about once a week. Doesn't seem to be related to outside temperatures.
Should I take it to the dealer for a check or back to the body shop? The body shop offers a lifetime warranty, but I doubt they could diagnose something intermittent like this.

I've had my prius for about 8 months now and to be honest, I'm not 100% sure how the climate control works. I just realized that one of the buttons I've been pressing is an air pollen filter. I've also recirculated the air and managed the fan speed with the up/down.

Have any control over the fan speed? The temperature? How does it work?

I have a 2010 Prius and I leave the climate control on. When I start the car the AC will only work sometimes. I can run errands, where I make 5 stops shutting the engine off each time. It will be hotter then heck in the cabin and after starting the car the ac won't blow air out the vents. Sometimes I can shut the car off and restart it and then the AC will turn on. When it actually blows air, it's nice and cold. If the car is on and the AC won't work, I will turn down the climate control to the coldest setting and it still won't come on. But the next time I start the car the AC might work fine. To me, it seems like a relay or something electrical isn't turning the ac on when the car is turned on. Or maybe the blower motor is getting stuck.

When I am using "auto" climate control mode, AC is automatically turned ON. I am somewhat surprised about that feature and I always turn AC off as most of the time I do not need AC and there is no point to spend extra energy when it is not necessary. Is it necessary to turn it off in this case? Am I missing something? It may be that AC will not actually be used unless the car inside temperature is above the target temperature that has been set, in which case I could leave AC ON, but I could not find specific info on this subject in my user manual. Why it is working this way?

The buttons to change the temperature in my 2010 Prius don't do a thing... The temperature is cool-ish as long as you have the AC turned on, and stays the exact same as you increase the temperature until you get to 85 and it maxes out, then it starts to get warm. As soon as you go to 84, it's cool again.
