View 2 RepliesStarted hearing a weird humming noise (not the usual hyundai hum in the front passenger side) coming from the front when decelerating from approximately 20mph down to a stop or from a stop up to 20mph. Went to a shop and ruled out wheel bearings, brakes, rotation, alignment, etc. Noise stopped.
Couple weeks later noticed physical resistance and upon accelerating to about 40mph it felt like I had a flat tire. That bumping, vibrating, shuddering feeling. No flat tire. Physical resistance, not power. Came and went in severity depending on terrain and speed. Brought it to a 2nd shop because the first was closed. The guy found codes that indicated the anti-lock brake system had failed. Said it should be covered under warranty and I should go to dealer.
Dealer replaced a brake switch (which has been recalled and was replaced before) and an inhibitor switch. They assessed the brakes too.
Car drives fine for a week and suddenly the brakes are screeching and we can't reverse out of a parking spot like the car is stuck on a snow mound but isnt. Rock it- in and out of forward and reverse to get out. We test it putting it in reverse again and car slams to a stop. When the car was pulled up on the tow truck we noticed only the rear driver tire didn't spin-locked up.
Dealer says no computer codes and that they just had to "adjust" the brake switch they had replaced. Drove home fine. Next day and for these next few days-something is still wrong. Physical resistance, not power. Cracking/popping noises when braking.
I have a 2005 v-6 and when I first start my car, its makes a real high pitch whining sound that will last for about 10 sec. before it starts to whine down.Then after that, its ok. It will not make any noise after that when I start it unless it sits for any length of time (6 to 8 hrs.) What might be the problem and If Its something I could fix myself?
View 1 RepliesI have a 2006 Chevy Trailblazer and the past few months, there is a whistling noise when I accelerate but only when the air conditioner is on. Now I have noticed that the air is not that cold. Would you know what the problem is?

View 7 RepliesI had an oil change done last week for my 03 trailblazer, and was getting valve tapping on startup after sitting 8 hours in the cold, it goes away after a few minutes. I stopped by today, and they looked through the maintenance records and noticed a new i.e., supersedes the old filter filter model had been used, they are going to pick up the old model filter and swap it out. I can get the part numbers tomorrow, but in 154 k I have never had such a noise. And it started day 1 after the oil change. 5w 30 as specs and level was full.
View 19 RepliesWhen turning in both directions, front end makes a CHEEP-CHEEP-CHEEP-CHEEP-CHEEP sound. Frequency increases when speed increases.Brakes are NOT engaged when this happens. Goes away when coming out of turn.
I am sure the problems could be multiple, but what is your first thought? Not that it matters, but its a 2002 Chevy Trailblazer.
I have a 2004 Chevy Trailblazer that looses acceleration. If I have the cruise control on it will the speed will decrease and then accelerate on level pavement. At idle the car runs fine. Could this be a fuel filter problem, an air flow problem or something else? Also the service light is on. I had it checked and the technician told me that the oxygen sensor on the exhaust needed to be replaced. I did that and the light is still on.
View 1 RepliesI have a 2004 Chevy trailblazer. I got in to got o the store the other day and realized that my rear door speakers were not working. I checked fuses and none were blown. I have a line out splitter attached to the rear speaker wires behind the stock radio for my subs. My subs are still pumping, so that tells me that the radio is putting out signal to those rear speaker wires, but still nothing from each of the rear doors. I am curious if there is a simpler way to fix this aside from taking the rear doors apart to check the speakers. is it possible the radio is shot? what are the chances that both door speakers blew at the same time?
View 4 RepliesI had an interesting ride home tonight. I accidentally lowered my front passenger window a little bit and when I tried to raise it I just got a clicking noise. So I drove along hitting the button, hoping the window would close, but it wouldn't. Then, the dash lights and head lights started pulsating/flickering. The engine power wasn't affected and the battery gauge wasn't moving. My vehicle is a 2002 Chevy Trailblazer with 173,0000 miles on it. Replaced the battery a few years back and have had no other electrical problems.
View 19 RepliesIs it possible to cause damage to a vehicle (2003?? Chevy Trailblazer) with an on-the-fly 2WD to 4AWD system by switching to 4AWD when the vehicle is in park or otherwise not driving forward? This was done by someone and now the vehicle is making a loud noise.
View 2 RepliesI bought a 2005 Prius base model with under 77K mi. A month after owning it, and about the time the weather got hot enough to need AC, I started hearing a squeaky moan (ish) noise coming from the ac unit when switching it on or off.
I took it in to the Nissan dealership and they listened and ID'd the noise as the "blender", and told me it was nothing to be concerned about (I do not believe that) and it's just a normal blender noise for an 11 year old car.
I think they didn't want to deal with it at all. (not that I'd want to spend the money, either, because so far the AC is working fine, but I can't shake the concept that it shouldn't be making that sort of noise at all (it wasn't there when I bought it) . I think it IS something that will lead to needing some sort of repair. Should I bring it somewhere else once my warranty is up?
What I am talking about? Should I be worried about this sound? (which seems to be getting ever so slightly louder each time).
2004 Trailblazer 6cy. 2WD - has been experiencing a very rough idle, engine shudders - no matter how long it's been warmed up. Wants to stall off red lights and at very low speeds. Not throwing any lights yet - but the speedo is out ( a cam shift typical problem for this car) so I don't trust the console for lights. Worse when the heat or air is on. Rides fine with more gas/higher speeds. Definitely worse in colder temps but continues even after 40-50 mins of driving. I've heard a number of things, but can't afford to fix them all. I've heard plugs, dirty throttle camshaft, sensors, cam actuator solenoid, etc. All seem to have people who said it fixed and didn't fix the issue. Worried I'm going to stall pulling off a stop and rear end someone any day now. Where do I start!?
View 2 RepliesMy '02 Impala makes a low moaning sound only in heavy rain and only if I am forced to drive through a large puddle.It first occurred a year ago after it had it's catalytic converter replaced due to the recall. The dealership mechanics checked their work and could find nothing. I tried spraying it with a garden hose under the car and under the hood while moving the throttle, still no sound. A local, and very thorough mechanic, heard the sound on a rainy day, but could find nothing. He could see nothing wrong, but thought that changing the serpentine belt would work. I replaced it with one from the dealer, but the sound still returns on rare occasions.
View 3 RepliesSo my car (2001 Civic) was having some issues that I needed to get worked out, so I was driving my mother's car for a few days. Within the first few minutes I knew there was something wrong, but I had so much going on that I haven't had a chance to get back to it for a while.
So she has a 2003 Toyota Camry with just 39k miles. Her work is about 2 miles away from home, so it basically gets driven there and to get groceries, and local clothes shopping. The car basically never sees the highway.
Hard to describe the sound, but it's like a loud rattling/vibration with every revolution of the front wheels. It sounds like it's coming from the front passenger side. Either the tire or the engine area. Here's a video of it on youtube. You can hear it pretty clearly under the road noise. It sounds kinda of like going over train tracks or something, and I'm only going about 45mph in the video. [URL] ....
So I don't know much about the car, but I am very familiar with my civic, so I checked out a few things. The tires appear to be in pretty good shape. About half the tread left with no unusual wear. I doubt it's the tires, cuz it really doesn't sound like tire noise. I checked the engine mounts and they appear to be in good order without cracks. Wouldn't expect an engine mount to go at 39k miles either, regardless of age. The car is garage kept.
Neither wheel has any side to side or up and down play like a bad ball joint, tie rod end, or wheel bearing would have. The steering wheel doesn't vibrate or anything. The sway bar endlinks appeared to be in good shape. I just changed the brake pads and rotors because of an unrelated issue. It didn't fix the problem.
A couple of things I will note: The belts are kind of dirty. It was really weird because half the belt is brown, the other half is black. It's basically split down the middle of one side. It's just dirt though, as I was able to rub some of it off with my fingers. The car was in a minor accident a couple of years back. It required me to replace the bumper and the passenger side headlight.
This make and model is the same as a Chevy Trailblazer. It has 124K miles on it, when it's cruising, there is no weird noise from the engine, but when I give it gas at any speed, there is a distinct sound coming from the rear of the engine. It sounds like when you put a playing card on your bike and the spokes hit it, but faster. The more gas, the louder the sound. It's gotten progressively worse lately. My first thought was rattling valves, but I'm not sure. It also sounds like a hole in a vacuum hose or something. With the hood up and an ear to the engine, the sound is definitely coming from the engine, not around it, and toward the rear.
View 2 RepliesI changed my plugs recently in my 2004 Chevrolet TrailBlazer 4.2l I6 with the coil on plug setup, and now it is misfiring and hesitating when I hit the gas. All the spark plugs have the proper gap and torqued down properly. I tried tightening down the ignition coils and on one I snapped the bolt. Of course my truck is staying parked until I replace the part which I have to order online. The only thing I can think of as far as the misfiring is not having a proper seat with the coils, my question is, how to get a better seating or if there are any other possible issues I could have over looked at all?
View 9 RepliesI've recently purchased an 02 Envoy from an auction. There are a couple of issues. The main one started last night. While at the store I put the truck in park and turn off the ignition. The ignition will not go into the lock position. I messed with the key and go it to turn off. Then started the truck to leave and couldn't put the truck in gear. I messed with the shifter and was able to put into gear.
At that point the gear shifter would move from park to reverse without me pushing the break pedal. I drove home and could not turn the key all of the way off again. Moved gear selector from 1st to Park a few times and then was able to remove the key. I restarted the truck and could not move the gear selector again; however I was able to remove the key easily.
I am leaning towards replacing the "Neutral Safety Switch" on the tranny but with my symptoms, I've seen brake light switch, ignition, and solenoid at gear shift selection.
Back up lights do not work either. Since I purchased the truck, I've replaced,
-Battery
-Ignition Coil
I have a 2008 trailblazer that the ac/heater doesn't always come on. When it does come on it wont stop blowing until the battery dies.

View 1 RepliesI have a 2002 trailblazer that will start fine in the morning and after it sits for an hour or two, but once i start it and run it for over ten minutes and i shut it off when i try to re-start it, it will crank but won't start. the dealer cleaned the throttle body and injectors, check the fuel pump for presure and it was fine,and they got no error codes?????? I've read that in can be the ignition switch??
