Kia Troubleshooting Questions? Ask a Mechanic
Hi, I'm Chad. Welcome to JustAnswer. I'm reviewing your question now, and I will post back with your reply ASAP
Can you tell me the year and model of your kia , so i can look up the wiring diagram and see why the compressor dont engage
are you getting power and Ground on the low pressure switch ?
power will come from the a/c control head and the ground from the pcm , can you check that ?
and i m assuming all fuses been checked ?
please let me know
ok great , thank you
If you jump the low pressure switch does a/c compressor kicks in ?
if you jumping the relay , we need to know are u missing ground on it or power
ground comes from pcm
power come from the a/c dash controller ,can you check and let me know?
so you missing a ground , you need to look into the ecm , itself , take it out and look at connectors ,see any evidence of burned spots , pin damage
also pull the middle a/c controller and inspect it fro the same
I m trying to confirm the ground to the relay is coming from ecm straight , i let you know , in little bit , kia weird about no showing diagrams just pin out connectors
