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 recently bought a 2005 Chevy Trailblazer LS EXT 4.2l 6cyl with about 129k miles on it. The vehicle is excellent condition and has no leaks on the engine or transmission. I took it for a test drive before buying for about 20min and no issues with it shift or rough idling.
After having the SUV for about a week, I noticed that it has a slight rough idle at red lights and gets a little worse when the AC is on. Twice now in the past week the SUV begins to sputter at the red light and then shuts off. It doesn't do this every time and I have noticed it happens more when the fuel gauge is in between the quarter tank E line. My father in-law is having a similar issue with his 2003 Trailblazer, same engine and make and model.
I should also mention that no check engine light comes on or leave an ERR code.
Throttle body needs to be cleaned: We have done this on my father in-laws and didn't fix the issue.
Replaced the spark plugs: didn't solve the issue
Read that it could possibly be the APPS sensor under the gas pedal: Haven't replaced this yet
Tighten or replace gas cap: Have done this, didn't fix
Have the idle reprogrammed: Have not done yet.
Could possibly be a fuel pump issue.
2005 Chevy Trailblazer. Whenever the temperature goes below freezing, the 4x4 selector switch does not work. After the car warms up (10 min), I need to turn it off and then restart it in order for the switch to work. I tried changing the selctor switch, that did not work. Is there some sort of solenoid or actuator that is freezing up?

View 3 RepliesWe own a 2005 Chevy Trailblazer, 8 cyl, 150K miles. Since July 11, the transmission has been slipping into neutral, usually when slowing down. This happens anywhere, and usually in slow (so far) traffic. My husband has been able to get the car to drive either in D3, or has been able to get it back into Drive, and the car just drives off like nothing happened. This usually takes a few minutes of turning it off and on, and shifting gears. Today he drove it in AWD, and it was fine (so far). He normally drives it in 4WD. They have been unable to duplicate this problem and, because there aren't any codes, cannot tell us what's going on. Needless to say, I've had it.

I've read that in can be the ignition switch??

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.

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 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 have a 2005 Trailblazer EXT 4wd. I have an issue with my front driveshaft. I have been hearing a squeaking in a tin can kind of sound. It is kind of hard to describe. I thought front brakes. Checked them and they are fine. I crawled up under the front end and took off the skid shield to look around. Since it was in 2wd I tried to turn the front driveshaft by hand and there was the sound. The driveshaft does turn and the sound was appearing to come from the front diff.
I thought "Oh Crap" is there fluid in the front diff. It would make sense if it was empty to make a sound like this. I unscrewed the filler hole and there was fluid. Then I decided to flush and fill the front diff with fresh fluid. It was pretty dark and I don't know when the last time the front diff was serviced. I took it out for test drive and still have the noise. What i am asking now is what to look for next? Like I said, when turning the front driveshaft by hand in 2wd it makes that sound.
By the way, 4wd works just fine in all modes.
I 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 14 RepliesWhat are symptons of a "bad" drive shaft? Just curious because during a recent trip to the dealership for an oil change a mechanic told me I had one(I had mentioned I heard a noise that seemed to speed up and slow down as I drove-kind of a whirring noise). He arrived at that diagnosis by pushing down on the hood with enough force to make the vehicle(2002 Chevy Trail Blazer w/4wd) bounce up and down - there was a clunking noise. I haven't taken it in to have it looked at more closely, mainly because I am afraid of the cost. What's involved in replacing a drive shaft? What's the cost? If it is really "bad" will it break suddenly and cause an accident?
