A/c snowflake flashing

[aalejandra]

Hi I have a 2007 Chevy Tahoe 5.3 I recently got in a crash it was the front right of my vehicle anyways I replaced the 3 outside body parts that were damaged no damage to the engine so far what did break was the coolant tank but got it replaced works fine. Ever since that happened because I didn’t use my a/c before that I don’t think anyway it turns on then after about 5 or ten min the snowflake Icon flashes the. Turns off. It’ll blow. Cold then when it flashes and does whatever seems to blow warm. It has good amount of the one a/c Can pressure thing so it’s not that also I believe my engine starts to sound funny when it happens that’s when I’m driving it. That’s a long story short but if anyone knows what it can be I would appreciate advice and ideas please and thank you

explain this gauge? how are you using it and what's it reading?

have you added r134 to it? added sealer?

without knowing anything, it sounds over charged to me if you've been adding to it. or maybe your cooling fans aren't working right after the crash?
