My auto-lock and security button on my keychain stopped working. I put in new batteries. When I try to reset it, it resets and then clicks and reset is gone.WHY?

Won't even turn over, nothing. Starts fine for a couple days, then won't start. Starts when jumped after the 4th or 5th try. Thought is was security system problem, and tried resetting that but still having problems.

The vibration goes away if put in neutral or park, or when the engine is warm. I have 125,000 miles on it and the transmission fluid & filter was changes at 70K and 120K. what is wrong?

I turn off the manual switch. Sometimes the headlights go off & sometimes they stay on. I haven't been notified of any recalls for this issue.

My '03 trailblazer has begun having some issues. I know the back pads are toast and I assume that's why it grinds to a stop. What I don't know is if that's the only thing making it do it. When I come to a stop it grinds hard and when the truck is almost stopped it grinds hard to the point that it feels like the truck is dying. Also it doesn't want to release when I start driving again. It's like something is staying engaged. When I speed up and slow down it makes a noise like I'm driving to fast in 4WD but when I switch between 2hi, 4awd & 4hi it makes the whining sound like it disengaged. 4lo makes the clunk it's supposed to. Help??

When cruising at approximately 45 MPH, the car seems to have a miss but I think what it's actually doing is continuously shifting in and out of overdrive. Coasting or applying more gas and the problem is not noticeable.

No other lights are on, gauges work fine, its confusing

Blower blows hot heat on one side of vehicle and cold heat on the other at the same time

I accidentally pulled the pcm fuse while it was running instead of the fuel pump fuse to relief the fuel pressure. Did the regulator swap and it all went back together great. Cat starts but is running super rough in park and in gear. Along with a new check engine light now. Wondering if I messed up the computer with what I did and can I fix this somehow?

quick struts install abs light on 1 days later.

Driving the tranny will suddenly slip and the engine will race drop it down a gear an it will take off fine and when you put it back in todrive you might go 1/2 a mile before it does it again
Is this common? is there a quick fix?
Whats the book time in case i have to go to a shop and does it run close to book time?
Thanks to anyone who can answer these for me!

My car is stuck in park and I can't get it to move. Is there a release button somewhere

When im at a stand still. Also my radio doesnt work when heater or ac on or ots cold out.

we owned our vehicle for 3 hours before a lady mashed the front end of it. The guy that towed it said that he was sure this vehicle had frame damage and to make sure they check it. So, when the adjuster looked at it, he stated that the hood was too mashed for him to even get it open and he couldn't crawl under the vehicle, so he said that the body shop would check the frame. Well, the body shop has tried to make the front end of my car line up and it will not. I have had it back to them 7 times and he finally said that he didn't know what the problem was. I asked him if he checked the frame and he said, "No" but that he could tell by looking at it that the frame was fine. He said that he didn't own a frame machine to put it on and check, so I contacted the 3rd party insurance who is having to pay for this, and they sent the adjuster back out. The adjuster said that it was a horrible job as far as the repairs go, so I asked him if the frame could be damaged and he said the body shop should have checked that. I told him that they didn't but tried to put it back together anyway. He crawled under the car and then said well I don't see any frame damage, so that's all we can do about it, even though my car will not stay together, literally, and everything is uneven in the front, the bumper has ripples all in it, like its just jammed in there, there is a 2 inch gap under one headlight, and only 3/4 inch gap under the other one. I keep telling them to check the frame and they say that they can tell by looking that the frame is ok. I think because they paid this body shop to fix the car, they are afraid there is going to be frame damage and they refuse to have it checked, but someone said that if there was something called core support damage, then 99% of the time there is frame damage, and the core was mashed and had to be completely replaced, what do you think about this? Thank you

Any time I drive over 55mph it shakes and it also bottoms out when hitting a dip in the road. It sounds like it is grinding on the front wheels and one of my front actuators isn't engaging for the four wheel drive, but you can hear the electric motor trying to engage.

If I replace the transfer case control module with one from another 2002 trail blazer, then do I need to have a dealership flash it?

transmission does not engage, the engine revs in every gear like its in neutral ???

2009 chevy trailblazer the headlights turn off intermittently and it is becoming more frequent. Tonight it did it three times for at least five minutes each time.
