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 ?

if you jumping the relay , we need to know are u missing ground on it or power

ground comes from pcm

while grounding the a/c relay the system will operate
Expert:  Chad Farhat replied 1 year ago.

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
