I have 06 4runner 4wd sport 4.7l. My evaporator core has a small leak. I hooked up my 2 ac gauges and saw it was just a little low so I decided to top it off. As i was adding freon the compressor cut off. I ran a jumper wire straight to the compressor and the clutch started turning and it got cold. So I know my clutch is good. I checked voltage and I have no power to the compressor or the pressure sensor. I checked the fuse and swapped the relay with the fog light relay but it still didn't work. The ac light stays lit up. Do you think my ac amplifier went bad? What powers the compressor? Thanks in advance.
