Thanks, that sounds like something that I could try. I have a bunch of 1N4007 diodes on hand, would those work as well? Otherwise I'll try it with the 1N4148 and see how it goes

Hey, taking measurements of the A/C request from pin 4V I have the following voltages FAN 1: 2.15V FAN 2: 2.8V FAN 3: 3.05V FAN 4: 2.9V

Hello there, I have a problem where the A/C only works on fan speed 1. On fan speed 2, 3 and 4 I believe the a/c clutch does not turn on and it only blows warm air on a hot day. I noticed that the A/C Request only activates on the first speed. Since the ECU software does not let you set a voltage activation threshold does anybody know the voltage required to activate the A/C Request? For background I had the system recharged recently, maybe a month ago and I had taken the car to check out the wiring and switches on the console and everything seems to work fine from what I was told. I think it's safe to assume that I have some issue getting a proper signal to/from the ECU as the a/c had worked with the stock ECU in place. Please let me know if you have any insight into this problem Thanks!
