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.

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
