Fan doesn't come on with AC

1998 kw w900 n14

So recently we got my fan clutch working and my AC.

Problem now is my AC works but the fan doesn't come on when it's needed so I have to run the fan manually as not to damage my compressor. We've checked everything. Installed a new fan switch and nothing. At this piont we think there is a broken wire.

Can I run a new jumper wire? Like from the fan override sensor to the compressor? Or where ever it goes? Does anyone know where a can run a jumper wire?

 

Okay so it is #8. That was my big question cause I wasn't actually sure if that was it. So my problem is likely between pin #8 and the high pressure switch, correct? Cause I can ohm that out and see if it has a broken wire in there

 

I think my mechanics have insite. Ill have to ask them. And that switch your talking about is the one called "unitary sw" on the diagram correct? that is the high pressure sensor/switch?

When we got the AC fixed we did try a brand new High pressure sensor and also put on a brand new plug as well.
