2002 Sonata GLS: Pushing the A/C button but A/C does not turn on. What can I check?

Discussion in 'Hyundai Sonata' started by Thee Chicago Wolf [MVP], Apr 5, 2010.

  1. I know I used my A/C as late at October of last year and it was
    working fine. This weekend, I tried to use it but when I push the A/C
    button (which did light up) I did not feel the usual initial engine
    strain associated with it and did not feel the air from the vents get
    cold. It's as if the A/C does not engage. I had recently changed the
    cabin air filter but this can't have anything to do with it as I have
    changed it myself on many occasions with no ill effects. Nothing was
    disconnected when I changed the filter and I was careful to ensure no
    wires go pinched, cut, or had come loose. Anything I should check
    first?

  2. 1.- Refrigerant level (too low).
    2.- Compressor clutch (wires and fuse).

    Given the age of the car and the time lapse since last used, I'd take a WAG
    and say low refrigerant. Could be a clutch problems, but that is less
    likely, IMO. Yes, even though it has not been used, it can leak. Sometimes
    that allows the deals to dry and harden faster. Time to find a good AC
    shop, before the big rush on the first hot day.

  4. Thanks for the heads up. I am surprised to hear that it could be low.
    My wife's 98 Corolla's A/C still run like a champ so I thought it was
    unusual for mine to be low (if it is). The dealership quoted me $169 +
    tax (leak test + recharge) and my personal mechanic would do the same
    for $100 cash. I do have a local A/C shop so I can always ask them
    what their rate is. Of course, if there is a leak, I understand that
    could mean big bucks to fix.

  5. Thanks for the reply. My mechanic will be taking a look next week and
    give me an assessment.
