Okay my sunfire has 104k miles on it and I have been having this problem for a while now that i can't figure out.

My car makes a strange sound kinda like shaking keys when i have the Heater or A/C off. Sometimes it does that sometimes it doesn't but what bothers me is, to stop that sound i have to turn the heat or air conditioner to defrost.

You hear a strange sound (i guess the fan) then it stops, the problem is my car will rev up when idle at times, Sounds like the heater turns off though it's still on then the strange sound comes back and my car revs up then the sound stops.

I notice it also does that when i'm going home from work on the highway, the rpm revs up and down as i'm gaining speed till about 50 to 55 then it stops.

Anyone know whats wrong, i wanna get this fixed pronto
