Default rpm high

greetings new to this site
i recently bought a 1999 ranger 4x4 manual trans,4.0(puskrod)for a the truck
heres my question:with fan control off or on when i turn the hvac control switch to ac or almost every position my rpm shoots up to about 900rpm,if i increase rpm and let off the rpm will stay close to where let off..even with ac compressor disconnected and vacum supply to hvac contol head disconnected and pluged off--rpm is normal otherwise
you all have any idea why
