recently had front differential replaced and the 90,000mile service done as per the maintenance schedule. Stability track comes on randomly, on the highway, for no reason, on straight, flat, dry surface. Stays on until I brake a little and keep braking a little in intervals and then it goes off. Very scary. No rhyme or reason for this. I love my car!!! Don't want to give it up, help!

when stabilatrack is engaged truck wont go .if I turn stabiltrack off it drives fine but sometimes makes grining noise.

Since this started I have also noticed that when turning the car off it shuts everything down, when it never did that before it would stay on for about 10-15 minutes before this happened.

Back up is this a problem or is this normal

Recirculation stuck. Would not cool for one trip home from store, cooling now just blower stuck on high cool. Must pull battery lead to turn off

No codes for two days then the light came back on

And I have positive to pin2 and ground to pin 6 and pin 5 the test light lights up and off with headlight switch turned on and off but pin 4 the when I put a lead into and attached it to positive on battery the lights do not come on any help where to go from here would be appreciated

you can't hardly here the noise at idle start up if you rev up it gets louder and even louder under load when you drive away.
you can't here it at all after 5 min. drive

the sound is very quiet at idle louder when rev up to 1500 rpm and louder under load when pull out of driveway. I just drove 2.5 hrs. on the highway at 70 mph the noise has not changed i have only owned the ss for 2 months. has made the noise always. the same every time cold start.

I lost powere to all interior lights and compounts while the vehicle was on the road a total of 4 times within the last 2 weeks. Also, I recently got one of the vent motors replaced and now when the truck turns on their is a loud clicking noise which lasts for one minute then goes away. Any help would be appreciated.

Are there fuses I should check? Can both head lights go out at the same time?

how to remove and install

I installed new original rear springs and need to adjust them. What is the D-height measurement and how do you adjust it? thanks

I had to pull the fuze to stop this .

This happens after driving 60 mph for 30 minutes or longer. There is no adverse power fluctuations.

Car will not fire. Thinking there could be a security porblem. Ignition switch, starter and solomoid has been replaced.

Trouble code P0336 and P0301
Changed crankshaft position sensor cleared the codes still will not crank I am not getting any trouble codes from the attempted start
Battery good
Starter removed tested good reinstalled
Removed CPS and reinstalled still no crank
Changed ignition switch just in case still no crank
Attempt start all power seems to come on I hear click of the solenoid but no crank
Swapped out relay 47 with 60 still no crank

I am running out of ideas any suggestions

I put the car in park but it shows on the dash it's still in drive and continues to roll forward. I placed my foot back on the brake but now the gear is stuck so I put on the emergency brake. I shut the car off and now it won't turn back on. Can I give it a jump start with cables and what should I do about the gear being stuck?

level sensor tell me more

And make them look new again?

the problem is current and constant day or night interior lights work but not instrument cluster light.

how do you stop odometer on ss trailblazer

i changed the factory bose sound system to a kenwood double din nav touchscreen and i had it professionally installed. after the install my chimes didn't work, my cruise control, and if you hit the onstar button the whole system shut off. Now most of that is steering wheel control and since the airbag is located in the steering wheel would it affect the deployment of said airbag.
