Quick question about ac pressure Solenoid.

Hey all I'm new to this forum.

I'm trying to help a buddy fix his a/c. So the first issue I saw was that the pressure was equal between low and high. The clutch doesn't engage either.

Just curious, I heard the ac pressure solenoid often goes on these. Would that cause this equal pressure issue? I know it would definitely prevent the Compressor from engaging.

Thanks for any help!
