Sinuous1

0 psi low side normal pressure high side. System was evacuated appeared a little low on R134A, recharged to no avail and the compressor is engaging with no crazy sounds. Worked fine driving to the fire station and 2 days later blowing hot air in AZ....currently 115 degrees. Help. I've already previously replaced the condenser and installed the fix bracket around 75K miles ago. Any ideas?
