Asked by Teencee Sep 19, 2022 at 06:52 PM about the 2005 Chevrolet Trailblazer EXT LT RWD

Question type: Maintenance & Repair

yesterday i replaced a tension pully and belt to stop the screeching noise
and it worked. this morning i started the car and it started screeching again,
even louder. well as i was driving off it was acting like it was wanting to die
(turn off). i manage to keep it running with a little press on the excel. i turn
the car off at gas station and when started the car to leave, it was acting as if
i was gently pressing the excel (also still screeching) it was like driving on its
own. why? what does this mean? why is it screeching again? also i want to
mention that when i turn on the air or the heat the car rumbles and then it
dies.. errrrrrr PLEASE i
need someones help?

I would remove the belt and try to turn all the pulleys by hand. A pulley bearing may be on it's way out and not rotating freely. When you turn on the air conditioning or defroster, this activates the air conditioning compressor pulley, maybe this is the culprit especially if it gets worse. There is one other problem with turning the "air" on and engine dying. It's a dirty throttle body. Remove fuses #10 and #28, then clean your throttle body. Very common problem and cheap to fix.

FJ4072327 PLEASE is there a way i can explain a few things to you about what all i have done to fix the problem and what 4 different people has told me that's including a 30 year licensed mechanic. i REALLY have this gut feeling your thinking in the same category as me and I'm determined to stick with it. I'm not familiar with communicating on here. hopefully you get a chance to read this and respond. thank you

Darn, I just saw this. I do believe this has a message center. Look at the profile I guess I did see "messages", or describe here.

FJ4072327 unfortunately i am still in this situation with my car. still i am needing your help. if you dont mind explaining to me a couple things and me telling you in detail of a couple issues that im having, even with a small vid clip of this would BE SO MUCH a blessing lol. if so could you email me at sweet_outgoing2008@yahoo.com therfor it would be easier exchanging messages and vids of the issue that way. its ok if you cant or simply dont want to, i just thought i would ask you meaning you know alot about cars and know more than i would EVER know about cars lol. thank you and god bless
