Had another a/c hose replaced on the wife's 2014 LWB about a month ago. Worked good after, but the a/c is acting up again. We've had a few warmer days since the repair and the a/c is taking spells where it isn't getting cold again. The dealership tested it again and they did notice the a/c compressor was making a slight noise, but nothing bad. The temps they got from the vents were cold, but it slightly started going up. The day they tested it, it wasn't a warm day. They said they need to be tested on a warm day to find the problem. Has anyone had compressor problems with their Santa Fe on here? We're running out of options. The wife is about ready to trade it off for something else.

Not knowing the history of the unit, but the control valve in the compressor, or as some call it electronic control valve, can cause problems at idle, on/off cold air, and ultimately no a/c. Although shops like to replace the entire compressor, the "valve" can be purchased separately, discharge system, old valve removed, new installed, evacuated, charged.

Years ago on our '11 2.0T went through no a/c upon startup, but maybe cold after a couple of miles, then no a/c at idle, no a/c upon restarting after a short trip, then no a/c. Actually no a/c when about 12 miles from home in 100 degree heat so wife said last time in that car, so as the compressor was making noise, rather than replace the valve, decided to install a used compressor ($50) with only 21,000 miles, still good and hopefully will continue in the future.

Thanks guys! I'll ask the dealership about that when we take it back. Could that valve make hoses bust open? We've had 2 hoses do that so far.
