Default Vibration in pedals when air is on
As title says. Air doesn't work(when fall weather comes I'll be getting vacuum line and doing that fix), but the defrost vents do, but now when they're on, the pedals vibrate a lot. What'* going out now? Thanks!

Does the vibration go away when you turn the blower motor off?

Possibly, unless something got inside of it causing it to be off balance.
