AC only works with Relay Jumped
 

I am helping someone with a 2001 Montero Sport. The AC switch lights up, but I have to jump the snowflake relay. When I do the clutch engages and it blows Cold. I tried jumping the Low Pressure Switch but still not engaging. I suspect a high pressure Switch issue But I can't find the dam thing and have been googling for hours.

the girl who owns it said she was told it was an "AC Module" which i don't think exists on this vehicle.

As I said before, when the relay is jumped everything works fine at idle and it gets COLD

Anybody have ANY ideas? Is there a high pressure switch on this vehicle? I can't find it but they are for sale on eBay apparently
