A/C pressure is good, not high or low. Radiator fan is good but not coming on when A/C is on. I unplugged high pressure switch and cooling fans come on, so I know fans are good. I'm thinking of a faulty low-pressure switch. I thought maybe the fan relay was not working right but I didn't see a cooling fan relay. Please help!!

A faulty low-pressure switch is your best bet, but we should run a CAN scan to see what comes up because it could be ab bd HVAC controller. you can get a CAN scanner (Controller Area Network) which will work on most cars from Amazon. here is a video to show you how. Also, let's check the fuses that run the system for power. This guide can help, and I have included the A/C system wiring diagrams so you can see which fuses to test and how the system works.
