Yes, they need burping. https://www.chevyhhr.net/forums/hhr-...-system-59224/

I'll try to burp it this weekend. Thanks.

MIND BLOWN:
So AC tech in Findlay (next town) charged me 20 (ended up being 50.xx) to do a basic test so he could(nt) find out what was wrong, so we could fix it at home.. What i got was a damn paper off with notes.

"AC Clutch Fully Engages
HIGH/LOW Pressure is adequate.
A/C Relay, swapped, stock #
Interior A/C on/off switch positive for power and function.
No Leaks detected."

That along with cost is what i got back. Like really WTF. Then recommended a tire shop, i was like "yea so they can charge me to tell me my tires are tires".

Did anyone check the diode? The pressure switch?

Im gonna have to contact them to see what was all checked (the list is literally a sticky note on the bill), how do you check those, if i can check em I will.

The diode is in the fuse box, check it for continuity in one direction only. Position #9.
Jump the pressure switch, if that fies it get a new one.

im assuming this is the proper pressure switch. diode checked out good.

when you say check it, just making sure doing it right, jump the wiring not the switch that is screwed in.

Actually, I was wrong about the switch. It is actually a sensor, the ECM does the switching.

A new one runs $10 (ebay) to $32 (AutoZone). EZ screw in job, there is a Schrader valve in the hole.

Ok. Still number 1 in the picture? I saw it just screwed off and screwed back on. Looks covered in oil from old motor.

Yes. The silver thing inside the red circle. Looking from the middle bottom upwards.
