Question about 1997 Chevrolet Suburban
My dual A/C cools the back real good but up front by the driver is not cold enough. Big temperature difference between front and back although front is colder than outside air. I filled the system with refrigerant and have about 45 psi in the system. Please help if you can thanks Kory
The system should have 30-40 psi on low side and 110-150 on high side. what i would first suggest is that you power wash the condensor coil which is mounted onfront of radiator this will allow more air over the coil. it will run more efficiently. also under the dash they have doors that blend the hot air off the heater coil with the a/c. there are servo motors that operate the doors either you have a defective servo or a stuck door which explains the difference in cab temps between front and back. hope this helps. please rate this solution. thank you
