I posted this awhile ago with no luck but maybe someone will know now. When I turn my A/C or heater on, it starts to vibrate really bad after i put it on the 2+ setting. It happened after i framed pretty damn hard on a whoop in pismo so I'm thinking something got jared loose. I haven't taken a look because i really don't know wtf i would be looking for besides something really obvious like something bent.
Any help?

Sound like something got bent in your blower motor or something, time for some dash diving!

lol, speaking of dash diving. i woke up and went out in the shop this morning and low and behold....my dad was bent down with his head up under the dash tearin stuff apart, he had a very similar problem with his OBS but it was related to the recirculation setting only

We get a shake like this in our 03' Tahoe and the dealer said its 'normal' WTF!

 

[zubyc]

Yah it is not normal...go to another dealer

 

[Slammedchevy01]

Yea I know its not normal cause my Grandpa's 04' Silverado doesnt have it and neither does my 01' Silverado or friends trucks for that matter.......it was just a lame excuse for the dealer to say that!

just out of curiosity, ......what is the 2+ setting? and what starts to vibrate really bad. i'll try to help but i am misunderstanding

this happens to my friends brand new trailblazer
his is EXTREMELY bad

He's sayin if he sets it on the number 2 setting or higher, his truck even does it on 1 its just quiet, the vibration is directly related...the higher the setting, the faster and more loud the vibration is

 

[Slammedchevy01]

Yea, I can feel the vibe thru the floor n crap its annoying! Dont really notice it anymore but its still goin in!

 

[Derek]

alright guys
as i stated before this happens in a friends brand new trailblazer
took it to the dealer today and what they found when they pulled it all apart was that some rodent go up inside there and built a nest and that was causing the vibration as well as the smell
the dealer said that it was a good think he brought it in cause if you run the motor with it like that it can blow the motor, his was fine but for those of you that have this go dash diving soon
also it is obvisouly not covered under warrenty
so if you park your truck outside you probably have the same problem
good luck and let us know what you find out

 

[zubyc]

Well since it happened when I hit on sand...maybe some sand got up there? :crazy:

 

[Slvrpismochevy96]

No way could that be it...something is broke/bent/cracked/....fucked

I've been in zubyc's truck and heard it myself...something needs repair

 

[Derek]

from what has been said it sounds exactly the same as his trailblazer

it vibrated so much the dash felt like it was going to fall apart and the floor vibrated so much you could feel it through the seat
am i correct?

 

[Slvrpismochevy96]

It vibrates quite a bit but its almost like something is loose, this all happened when he slammed his truck really hard, so i doubt theres a rat in his box

Just sounds like his blower motor/fan are screwed or come loose ... if you turn the key on but not crank the truck, and turn the fan on and it does it theres nothing else it could be .. need to tear into it and see what is wrong.
