Thread: Heater issues

Your engine is not failing. This is a sign that there is A. Junk in the blower motor causing it to be off-balance, or B. the motor itself is starting to go bad and is allowing the squirrel cage to flop a bit and vibrate. Let me guess, you can feel it in the pedals when its on 5 and vibrating, right?

As far as your car vibrating more than it should at idle, when was the last time a tune-up and vac. leak check was done? I'd start there before anything.

Just drop down the blower motor its only a couple screws holding it in. I've seen the cages crack and also cause a vibration. Id say more than likely just a blower motor. Some come with cages some don't.
