Silverado :: 2004 - Climate Control System Occasionally Go To Completely Hot?
Jul 16, 2011
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.

Do the climate control can be turned off completely? I understand that "econ" shuts down the compressor, fans, etc... but can you make the whole thing go "dark"? If so, how can this be done?

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.

The climate control can be completely off (fan, everything)... and my vents will commonly continue to blow (room temp) air. Don't know if I'm missing something here. This is while in motion or stopped.

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.

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.

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?

I just have a quick question.. I have a 2004 v8, and every time I start my car the climate control comes on, I tried to put in auto and manual. How do you turn it off, so it will only come on when you want it to...not during every start up?

I have checked the fuses and they are all good. I turn on the headlights and the dash lights do come on at that point but I have no power to the buttons on the panel or any of the climate settings.

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.

Seems like I'm having to crank the temperature up higher and higher (numerically) to avoid freezing myself out in the GX in the summer. Used to be ~72-74deg was a comfortable setting, regardless of outside temp. Now it seems like I'm running a 77-78deg setting on the climate control in order for things to feel right. Any lower and I just get frozen-out.
Oddly, if I have the rear AC on (if it's super hot outside, or if the kids are in the back) things are a bit more normal.

I just bought a 2007 and my Multi Information Display does not work properly on the climate control screen or information screen. ie when you press temp up or down buttons it sometimes works and when you want to change the fan speed and press medium it goes to low. On the information screen no matter what you select it goes to Trip information screen. However the Audio screen works perfectly.

Yesterday all of a sudden the lights on the instrument panel started flashing and the RPM indicator started fluctuating . The RPM indicator would rev and bounce all over the place while the engine was. At a constant speed. Same thin happened before when the alternator went. Next the A/C sort of went and the NAV screen showed Air Condition Diagnosis with no options to change the climate control on the screen. When I got to the car I noticed the 110v ac button was on, not sure how long she had it engaged. I turned if the 110v button and unplugged the battery to reset the computer. All seems fine driving it for 20 miles now.

From time to time, climate control will stop working. Buttons are not lit up or responsive, fans do not work, and computer doesn't show outside temperature. Problem can last a day, an hour, 10 minutes, or any other time frame. Most of the time once it stops working it will not start working until left parked and locked overnight. Sometimes when we start driving it would all of a sudden start working on its own. This has happened during multiple seasons and multiple weather conditions.
I took the car to Lexus dealer who decided it would be a smart idea to replace the whole climate control unit in the dash, well this past weekend the problem occurred again with brand new climate control unit in place.

When I park, the climate system adjusts to send air down to the foot wells. The climate system keeps the air running long enough to drain the left side battery. I replaced both batteries two days ago. This morning my, brand new, left battery was dead again. The first two weeks I owned the car I never noticed the climate staying on, only the last 6 days.
