Default 05 Wrx Ac chirps every 30 seconds

I rarely use Ac in my car cause it seems to run worse idle goes a up and down which is somewhat normal just seem more violent. Almost seems like it wants to die at lower rpm starts from a stop sign or light. But the worst part is every 20-50 seconds the belt chirps once (assuming itís the belt) and the car jerks, like it loses power. Set cruise at 120km/h on the highway every 20-50 seconds it chirps once and jerks. It feels like when you manually turn off cruise with the button the turn it back on right away and you feel the car start to pull. Does it with or without cruise on
-21 psi on gauge with Ac off.
No chirp if Ac is off so not sure how that works because isnít the belt still moving when the Ac is off??

Thats normal operation, but try to tighten your belt a little more, twist it with your fingers and it shouldnt move any more than 90*

Gauge readings are worthless unless the compressor is running. If you overfilled it, that will make it harder for the compressor to spin, adding more drag to the belt, and causing it to chirp every time the compressor cycles on.

Try cleaning out the A/C compressor clutch. Just get some compressed air and blow out the clutch area, and a cloud of dust should come out. The clutch can get pretty dusty from normal usage, and the clutch can get noisy/jerky from slipping with the dust.

This is a simple fix. All you need to do is tighten up your AC Belt.
