GoodDay, everyone have a proble with my nissan sentra 1997 model
when i turned on my a/c rpms go down. but, if i unplug a/c compressor clutch socket and i turned on a/c switch rpms go up.
i need your reply to solve my problem to my nissan. Thank you guys.
I would guess it also happens when you turn major electrical loads on or turn the power steering ? Usually it will be just the inlet air control valve
and throttle body needing cleaned with throttle body cleaner or similar. So I would try that first before looking any further.

Agree with Andy on the throttle body cleaning being your first step.
What you are describing would be a normal reaction (rpm rise with ac clutch disabled)
The computer sees the input that a load is taking place so the command is there to increase the IAC position to account for it. But the load isn't actually there.
