2010 Hyundai Santa Fe Limited AWD 3.5L 46K Miles

I have a problem and a question that I am hoping others may have information about. I have looked / searched through the forums and have not found the answers to either that seem to address my scenario.

First problem pertains to the A/C system. Lately, I have experienced the A/C shutting off for no apparent reason while driving (a/c is on manually, not using Auto temp settings). The air continues to blow from the vent, but becomes moist / humid and warm. After a considerable increase in interior temp, the a/c does not cycle on or cool at all. This has also occurred shortly after adjusting the temp up a couple of degrees (say from 65 to 67). When I increase the set temp, the a/c begins blowing moist / humid and warmer air. And yes, I do realize that the air should not be as cold, but it should not be moist since a/c also dehumidifies air. I've pulled over when this has happened and confirmed that the a/c compressor clutch is not engaged (thus the a/c comp is rotating) even thought the a/c button light is illuminated. If I turn the key off and restart the car / engine, the a/c will begin to function again blowing cold air. Sounds like re-booting a Windows-based computers....

My second item is a question of the seatbelt chime. Has anyone successfully disabled the chime on a 2010 Santa Fe? Some forums refer to a chime module under the dash on older Hyundai's and it sounds like newer models have the chime built into some other module buried in the center console. Is there a DIY process to disable it? Or is this something the dealer can disable?

Thanks for any help / feedback.

 

Sounds like you may be low on refrigerant. Get it checked by a dealer. It's under warranty.

Yes, it's very easy to disable. The procedure is listed on page 3-18 of you owners manual:

No, it can't be disabled. It's integrated in the Body Control Module (BCM).
