Vibration when turning on accessarys
When the A/C is on? Compressor may be getting weak and starting to drag.
Good answer! Can I check that by taking the belt off and seeing if it spins freely, or is there a better way?..should it have some drag? .
the pulley will free spin until the clutch cycles when it cycles is when your getting the drag. Should be no drag on the pulley, essentially the a/c compressor is a pump and all pumps need adequate lubrication to maintain there health
does your compressor rattle, knock, or chirp? Some 4 cylinders are prone to sufficient power loss when the compressor is on regardless.
No, doesn't make any noise, idle kicks down a little due to running it..MAF sensor? No loss of power when driving, it vibrates in the steering wheel when I put it in gear, that is why I replaced all 4 mounts its a lot better, zero vib when in neuteral , and when really warmed up normal vib in gear
It also does it when turning on heater..so more of a fan draw?
