Want this question answered?
what cause the ac light to blink on a 1999 Toyota sienna
Tire pressure warning light
I have a 2000 sienna..........and had that light come on......in has to do with the braking system
Tire Pressure
According to my 2000 Sienna manual, an exclamation point in a circle with 2 parens on either side is a brake system warning light. Might want to get your brake system looked at.
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.
Because one or more of the tires is low. If you just had replaced one o more tires, there is need to reset the warning light.
Check brake fluid level in master cylinder Check to make sure parking brake is fully released
how do u change the license plate light on a 2005 sienna
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 work again, until a week later and I have to repeat the process.
I believe it is blinking because there is a misfire inside the engine. Meaning that the timing is off. This could be because the timing belt may be old and the teeth are chewed and are not as rigid. That was the case for my 96 tacoma.
not valid
