I've been having some issues lately with the ventilation in my Santa Fe. I'm not sure if it's A/C related or if it's more of a general issue with the ventilation.
My wife typically drives the vehicle and noticed the issues. First, she noticed that even when the car was off (and key removed), the light on the button to select inside vs. outside air would be on.
Next, the fan would not turn on at all at any fan speed or any vent setting (feet, bi-level, face, defrost). The fan will come on when the car first starts, but after running, it just stops. No noise or anything, just shuts off.
Last night, it happened while we were driving and initially, I could just turn the system off and then on and it would start back up, but then shut off within a couple minutes.
Today, she noticed when either the A/C or the defrost was turned on, some water shot out from somwhere underneath the glove compartment near the passenger door.
Tonight I pulled the glove compartment off and looked in the air filter casing (there's no filter in there) to see if there was any sort of build-up, and there wasn't anything major. The fan seemed to be blowing plenty of air through without issue. I looked underneath and saw where some water could have come out... I'm not familiar with the names of any of the equipment under there, or what it does. Where the water came out was near what looks like a motor or compressor on the passenger side just underneath the glove compartment on the far right side. That's the best I can describe it.
I put everything back together and the wife went to pick up dinner. She drove about a mile with everything running fine with only the vent on (no A/C or defrost). However, once she turned on the defrost, the system shut off. I'm guessing then that it's something to do with the A/C, because most of our driving of late has been done with the defrost on because of a lot of cool, rainy weather. I initially thought that the wetness and humidity from all the rain could've just caused some sort of condensation or something in the system, but now I'm wondering if it isn't something more serious with something in the A/C system.
Whatever is the problem, it causes the whole climate system to be unresponsive. When the fan shuts down, it doesn't start up even if the A/C or defrost is turned off.
I would appreciate any thoughts or suggestions as I'd like to have an idea of potential problems when I take it to a mechanic. Thanks.
