Vehicle speed and RPM is fixed. If the car goes 85 MPH @ 3000 RPM, having the A/C on will not change the RPM unless the speed changes also.

Maybe this will help explain why:

some nissan automatics have a locking torque converter - I had a 4spd automatic Sentra that was like that. If you were just cruising you could feel it lock and the rpms would drop just a bit, bit if you hit the gas a little it would unlock and they went back up. nothing big, maybe 2-300 rpms diference.
