I have a 95 Corolla that had an AC leak in the condenser. I replaced the condenser and drier. Then pulled a vaccum on the system for the recommended 30 minutes. I then added 2 cans (12oz) of R134a. Now, when I turn the AC on, the system pulls a vaccum on the LP side and the HP side remains at about 140 psi. What are the likely causes of this? Before the condenser failed, I had not had any troubles and the system was nice and cold. A used compressor was installed about 5 years ago.
