What causes ac lite and recirculating lite blinking?
It depends on the vehicle, some will blink like that when the refrigerant level is low.
It's telling you the revolution sensor is not matching the revolutions of the engine. The ECU takes over and cuts current to the AC when this happens and the ac light will start blinking. A turn the AC of then turn it back on and it's not blinking tells you the problem is going to lead to no AC if you don't get it fixed.
If the AC light is blinking in the Toyota 98 Sienna, it means that something is internally wrong with your AC, it has stopped working, and it is recommended that you take it to the dealer to repair. This is not a very specific answer, but that is exactly what it says in the user manual. I find if I stop, turn off the car and AC for about 15 minutes, then restart, it will…
Kinda, but it'd be real inefficent and expensive. Think about it: at one end of the room you have the AC making cold air. At the other end you have the fan, blowing that cold air out of the room. Means the AC has to take in new warm air from the outside and cool it. You're better off having a large portion of the air in the room recirculating. That way the AC doesn't…
Your blend door may not be working right. This controls the mixture of hot and cold air. Max AC bypasses this by recirculating air from inside the vehicle. If this is your problem, it may be expensive to fix. However, there is a way to rig it up for free, at your own risk. For more details, see: http://www.blenddoorfix.netfirms.com/ It worked for me.
The problem with your air conditioning light blinking in the 4runner is a bad relay. Toyota has updated the relay to part #90987-02028. Call your local Toyota dealership for this relay. You can buy it at the parts counter. It is about $65. It takes 1 minute to replace. This same procedure is for the Camry and other Toyota models with the same blinking AC light, but the relay part number might differ.
I notice the light blinks when the AC is left on and the temperature drops significantly when the car is re-started next. When the temperature is too cold, the AC will not engage. I have also seen it come on sporadically when the refrigerant level is low in the system but I don't know if that is supposed to happen, it could have been a coincidence.
Probably one of two things. 1) Its running VERY lean, then with the extra load of the AC, things only get worse. Check fuel filters and air-cleaner element. A few seconds on a good 4 gas analyser will confirm the problem instantly. 2) Too much advance in the timing. Easily verified with a timing lite.. Lucky you, OBD1 car. Not a lot of computer stuff.
I have a 2003 4 runner limited with about 70000 miles. When I push the AC button the AC comes on for a few seconds the cuts off and the light starts blinking. What is the cause of this?
I know the secret and know its pretty easy , hold down the top and bottom four approximatley four seconds , you will hear the heater system run a diagnostic from cold to hot wait for lights to stop blinking realease bottons if this fails you have a problem within the system ancient Chinese secret pass it on !
The Nintendo DSi has two cameras, which can be used to take pictures or play games. DSiWare can also only be played on a Nintendo DSi system. Plus, the DSi can record, play, and edit music and sounds. Externally, the DSi weighs about as much as a DS Lite, but is slightly larger and has larger screens. DSi systems can use SD cards, but have no slot for Game Boy Advance games. The DSi stylus…
