When I turn on the blower, either heat or A/C, every 10 seconds or so the idle will increase. If I'm at a stop light when this happens, it will cause the vehicle to jump a little and the RPM will drop almost enough for the engine to die. Once in a while it actually does die.
I'm no doctor, but I popped the hood to have a look anyways, and it seems like the idle spike is caused by the A/C compressor engaging.
On hot summer days, I'll even get a loud humming sound. But I'm not sure if it's comming from the A/C compressor. It seems like it's more comming from the power steering since the pitch of the hum changes a bit as I turn the wheel.
Are these problems related? Is my A/C compressor &/or Power Steering going bad? Is it normal for the A/C compressor to kick on so often?
