What should the low pressure side be at on this year? I read a post that said if it's between 50-90lbs that the freon is low is that correct? My guage reads 80lbs and it is in the red warning side of the pressure guage and don't want to throw a can at it to find out that there is something else wrong.
It doesn't blow cold air, haven't tried jumping the relay or anything yet just wanted to find out about that pressure reading.
When the compressor is not running, the low & high pressure sides will equalize in pressure. If you are seeing 80psi, that's more than enough pressure to allow the compressor to kick in. A normal operating system 'should' show somewhere between 30-40psi, preferably around 32-35, on low port with system running. I think you have an electrical issue.
