Re 1999 Toyota Avalon XLS
I have a hi side pressure switch but can not find a lo side switch. I assume compressor on/off is controlled by ECU and hi side switch is there only as fail safe. The reason I ask is because it seems like ac is cycling more than usual. I can see a few bubbles in my sight glass so could be a little low on refrigerant - will hook-up gages tomorrow. Getting about 44 degrees from vents. Does anyone know if there is a lo side switch on my car? Can anyone confirm that compressor on/off is controlled by ECU vs pressure switches? Thanks.
