My aveo 5 ac system shows 100psi in the low line and 100 psi in the high line when the engine is off. When I cranked up the engine and turned ac to max, the low line showed 65psi and the high line showed 150psi. The compressor clutch kicks on and runs but no cold air. The outside temperature is 90 F. The temperature in the vents while the ac is running is 85F. Any help would be appreciated.
