I have 97 gtp when i turn heater onɪ to two its fine when i turn it on three it gets loud and interior starts vibrating when i turn it on 5 it gets louder and vibrates more What could this be heater going out
 


The way you describe it, I think there must be some garbage caught in the squirrel cage of the blower motor. Or the cage itself is fubarred.
 
i hope its not engine starting to fail. I did hook it up to computer didnt throw any codes. WHat else did your car do before it failed like when its idling it vibrates a little bit more then it should
 
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.
 


well when its on two its fine but the higher i go louder it gets and the sound is not in the engine its toward windsheild is that where blower motor is should i replace it
 
Look at it this way..take a ceiling fan. Turn it on low it spins fine. Remove a blade or add weight to one. Now its off balance...though at a very slow speed you don't see it. Crank it up a couple notches now its all over the place.

Remove the cover under the passenger side dash. You'll see a big black dome thing with a couple wires coming out. 3 or 4 screws hold it in. Remove those it should slide right out.
