Corolla Rattle Noise & Vibrates when AC is turned ON

[mwoipee]

Hi everyone,

I wanted to ask your input, I do not know anything about cars.

My car is Toyota Corolla GLI Automatic. I had to replace my stock radiator with 2-rows radiator.

After then, I am starting to hear extensive vibration and rattle noise when the AC is turned on. I do not experience this before, just like right after my radiator was replaced. When I turned off the AC, the noise/vibration will go off.

Is there any connection when I replaced it with 2-rows radiator? Should I directly go to a mechanic or a Car-aircon specialist?

It could be the engine's idle-up that is causing the problem.

The engine rpm should adjust higher whenever you turn on the aircon to keep the engine running smooth.

Ah! I think that's the one they tried to adjust.. Pero nung inadjust nila parang nawala. Then the next day, biglang narinig ko na naman ulit. Para syang may malaking makina sa loob na super ingay.

They call it as Idle Up Sensor? Do you guys have any idea how much it costs?

Less than php 1000. Brandnew pero hindi siya "toyota genuine part". Gumana for 1 year and 5 months tapos 'di ko na alam kung ano na nangyari since binenta ko na tsikot.
