09’ Vibe AWD Check Engine, VSC, Traction, AWD lights with AC on

[eriksenz]

Hello! We’ve been running into an issue where our check engine light, traction control, awd, and vsc off (blinking) lights come on when the air conditioning is in use for 20+ minutes. If we turn off the ac, 2 startups later the lights go off. We had the code scanned it came up as “engine control module”, but it’s weird that it’s only when the AC is on…

We live in the northeast, so we’ve left AC season and haven’t had issues with the lights coming on in over a month, but I wanted to see if this has been a problem for anyone else or if there’s any ideas/solutions out there?? Thank you!!

I have to same problem except these dash lights are on all the time and the AWD is on all the time. I will post when/if the problem is fixed.
