    Help me mga masters. My 2008 Toyota Avanza J seems to have an idling problem. The RPM goes up and down when the A/C is on and there is a clicking relay sound. This only happens when on full stop with A/C on. Youtube video below:

    parang nangyayari yan pag nag eengage yung compressor ah...
    siguro best thing you can do is to have your compressor and its related electricals checked.

    Did you have AC work done? Your AC circuit is experiencing hi-pressure. Kaya erratic on-off yung compressor.

    From comments in the youtube video someone cleaned his servo (IACV) with carb cleaner and fixed it.

    So I guess the real problem was a blocked or failing IACV.
