Ever since installing my MSPNP2 on my 94, my AC stopped working. When I hit the AC button I get the green light showing AC to be on but the passenger side fan never turns on (even above 220 degrees) and the AC compressor clutch never engages. I know there exists an idle up setting for AC but that obviously does nothing if my AC compressor is never engaging in the first place. Are there any other settings to check? I’m noob, thanks.

*attached the .msq, thinking it could also potentially be that my freon leaked out causing the safety switch to never activate (but would rather check the ecu settings first)*

Check the outputs in your settings to ensure the correct one is selected.

Am i in the right place? "Boost/Advanced" -> "Programmable on/off Outputs" ? and are any of them related to AC, I have FIDLE and Tach out which i dont think are related. Output1 which is for controlling the driver side fan. As well as output2, InjectorC and D, and Boost.

Sorry, should've thought to include that in the first place. Edited the original post, thanks.

Your AC idle up is turned off.

Even when i turned it on, it didn't change anything. I tried both the Launch pin and tableswitch pin at high and low... AC fan and compressor still never came on.
