My ac light started blinking, ran diagnostic on the nav screen and came up with code 21, bad solar sensor. The clutch would not engage without jumping it. I bought a set of gauges and rented a pump, evacuated the system and it held a vacuum overnight. I went to add coolant with the gauges in the low side but it will not pull refrigerant into the system with the clutch engaged. Could this mean my compressor is bad? Any help would be greatly appreciated!
