Kia Troubleshooting Questions? Ask a Mechanic
Hello. My name is ***** ***** I will be helping you today.
When its blowing warm is the compressor running?
Watch the compressor and see if the clutch part is turning.
OK. There really isnt a lot I can do to help if you cant get it to act up.
OK. And if you adjust the temperature from cold to hot and back to cold does that change anything?
OK when its blowing warm air feel the metal A/C lines going into the firewall. What do they feel like?
OK. The problem is electrical. Most likely the temperature door actuator.
Are you wanting to fix it yourself?
Do you have a multimeter to do some testing and verify that?
OK. I am attaching a pinout of the actuator as well as the replacement instructions which should help you locate it for testing. When it is acting up check the voltage between pins 3 and 7 and let me know what you get.
Sorry here are the attachments.
Alright. Let me know if you need anything further and please be sure to rate my service so I get credit for helping you today. Thanks
If the low side pressure is too low to create cool air it would not let the compressor run. I have my doubts about their diagnoses.
Being low on refrigerant is natural. The molecules of R134 are so small that it does leak just a tiny but and needs recharged over time. The vehicle is 5 years old so its about that time.
If it works after charging it then I stand corrected but that sure seems odd., Either way if its low it needs topped off so it couldnt hurt.
