Why did my check engine light come on at the same time my AC quit blowing cold?

Asked by Melonie Jul 16, 2021 at 03:56 AM about the 2014 Kia Sportage LX AWD

Question type: Maintenance & Repair

I have a 2014 Kia Sportage and I just bought it about 3
months ago. The dealership I bought it from recharged the
freeon for me because the air wasn't working at all to
begin with and I told them I would buy it if they recharge
the air for me. It has worked great up until today when I
was parked at work and all the sudden the check engine
light came on and then I noticed the air was room
temperature. I turned the car off and then back on and it
started blowing cold again for a few minutes but then
started blowing warm again. I began to drive and it started
blowing cold again but then when I left work tonight it was
blowing cold again and  working fine, even while sitting
still. Granted it was way cooler outside once I left work,
compared to when I arrived earlier in the day. I don't know
if the temperature outside or the fact that I had my car
running for several hours straight already had anything to
do with it or not. I do know that I can't see how the freeon
could be out already and whatever the case may be I need
to fix it fast because I have an 11 month old and she can't
be in the car without air or she will burn up in this hot
summer sun, especially because my car is black with black
interior. Someone please Help! -

Scan for codes. Never buy a car that "just needs a recharge" as there is a leak that should have been fixed.

Most auto parts stores will scan the computer for trouble codes for free. I'd suspect the coolant temperature sensor. If the computer stops getting a signal from that sensor it will assume the engine is overheating. When that happens the check engine light will come on, the air conditioning will be disabled, and the radiator cooling fans will come on at high speed. Hope that helps! Jim
