AC NOT BLOWING COLD AIR

2000 Cadillac Deville • 122,000 miles

I cannot get car to blow cold air I checked freon, compressor, belts, fluid. It will bow out very hot air on passanger side an ambient air on driver side an rear air. Never felt cold air since I bought car. Freon compressor are fine. Also no outside temp reading on my digital dash bord its blank. Please help!

Advanced auto is parts salesman, not techs.

We need the pressure to see what is happening so we can further help you.

I said I used an advance auto pressure test I felt like that was a cheap test comared to a shop test. An I cant remember exact but the needle was right next to the red but still in the cold but very close to the red! (Preasure test)

Ok, sorry about the advance.

Can you hook it back up and give us the high and low side pressures while running? Pressures never are a sign of freon level but it will help us in determining other operations
