If the ac switch is blinking, one of your sensors had detected an abnormality in your system.
either a low pressure in the system, a high pressure in the system, or a stuck compressor.

if you know anything about ac and how to repair it then i could guide you. but if it needs charging of gas , then i would suggest that you bring it to a qualified tech to do the charging.


tnx 4 using fixya,

The blinking light indicates a fault has occurred in the system, since the dianostics require special electronic test equipment the dealer is the only option.

2006 Toyota Sequoia AC light on dash stays on and AUTO button seems stuck. Did what the manual said to do and it did not work. How do I get the auto button off and is it going to burn out my AC compr


That won't burn out the compressor. It could be dead already. There are several things that will keep the light on, in the dash. High, low pressure switches, A/C .heater controller malfunction, wiring, and the compressor is bad. All these turn the light on, but all will shut down the system. Put it on a scanner and find out what's wrong.

Tip

Toyota Air Conditioners


This tip pertains to maximizing the cooling efficiency from your Toyota's Air Conditioning system.

(The info that follows is for vehicles that are not equipped with "Auto" AC.)

On really warm days, nothing is better than getting in a hot vehicle, and turning on the AC for a nice comfortable driving experience.

In our service facility, we continually see customers who are not totally satisfied with their AC output. Hopefully, this tip will address those issues, and just might be useful to you.

The number one reason for poor cooling with the AC on, is neglecting to select the "Recirculate" function on the heater/AC control panel.

What is Recirculate?
That mode is where the AC system 'recirculates' the air contained in the car, thru the AC box, over and over, until the desired temperature is reached. The Recirculate button, knob, lever or slide is easily identified by seeing a picture of a little car, with an arrow doing a 'U-Turn" inside the car. This is the opposite of the "Fresh" mode, which is an arrow going 'straight through' the little car icon.

If you are using the "Fresh" mode, you are actually admitting ambient air into the car. Ambient air is much warmer, and makes the AC work harder, and you will see a 10 degree rise in the air temperature from the dash vents. Also, some vehicles admit the 'Fresh' air from under the hood, so, leaving the 'Fresh' mode selected could actually draw in the much hotter underhood air into the AC system.

So, what to do? Anytime you use the AC, please verify that the Recirculate function has been selected. As stated above, this uses the air in the car over and over, and your cooling efficiency will be 10 degrees colder. You can easily check and verify this with an 'instant-read' thermometer. Put the thermometer in the center dash vent, start up the car, turn on the AC, select Recirculate, and watch the temperature drop. It should stop dropping around 34-36 degrees F (depending on humidity, sun load, and a few other things). Now, when the temperature is as low as it will reach, turn off the Recirculate device. You will see the temperature actually rise, maybe 10-12 degrees.

Some additional info: As long as the car is in Recirculate mode, the AC compressor will eventually turn off, when the interior makes the selected temperature. This saves you gas. If you run the AC with the fresh mode selected, the AC compressor runs all of the time. This wastes gas, and costs you more money.

The best way I can easily sum up Fresh versus Recirculate is this:

Running the car with 'Fresh' selected is like running your refrigerator with the door open. It works, but it does not work good. Choosing 'Recirculate' is like running the fridge with the door closed.
If this tip helps you, please leave a positive helpful rating. Thanks!

2004 camry ac light blinking and throws hot air. Suggestions?


My 2003 Toyota Camry AC often starts blowing hot air and the AC light starts blinking. I don't know why the following process works, but it does. Using the temp selector (left) reduce the temperature all the way down to Max Cold and then push the Auto button. It will start blowing out very cold air. After a little while push the temp selector to the desired temperature.

My 2005 Tacoma's ac light blinks and there is a sqealing sound when I run the ac. Any ideas?


Sounds like the AC compressor is out. If you are handy and want to fix it yourself, you will save anywhere from $1200-2200. The compressor is sold on an online auction site for just under $400 - far less than the $700 from the dealer. I am having the same issue and will be attempting the fix shortly. Good luck! Also, the service manual is also online showing how to do it.
