Can I drive 2005 trailblazer without worring if airbag will go off if there is a recall on them ?

Once it is started it runs fine. It did not act funny driving but when I turn it off it wont start.

Front blower will not work, It gets stock in park and will no shift

I have an 05 Trailblazer 4.2 I6. recently my antitheft has been locking me out inconsistently for always different amounts of time. i have read alot on passlock issues and followed a similar article in how to diagnose my passlock sensor. upon doing these tests though i recieved different results and am unsure as to what they may indicate. when i tested my Red/White to Orange/Black i got 13.3v at IGN0,IGN1,&CRANK. the Yellow to Orange/Black read 4.3V in all positions. this was while the vehicle was running. when it did the no start R/W to O/B read 12.1v in all positions, and Y to O/B read 4.2. from what i understand the yellow is supposed to dorp to an unknow value upon IGN1&CRANK. not sure what it indicates, any help would be great.

There is nothing in third gear when shifted manually. Also the speedometer is not working. The shop thinks it is an electrical issue. I need some help, I have to have this vehicle for our business!!

what all should be done

I never know how much gas I have left, gas level does not work. Also I do not know how fast I'm going because my speed sensor does not work.

My daughter left a car seat warmer plugged in over night and my battery was dead the next day. I jumped the vehicle and it fires up nice and smooth and sounds like everything is great, but the car runs for about 1 second then shuts off. My key fob will no longer unlock the car or do anything, the locks won't engage or disengage when the button is pressed, the stereo won't turn on.. The dash reads Unknown Driver instead of Driver 1 Driver 2.

I tried the 30 minute reset procedure, but I may have done it wrong, because there is no SECURITY light that flashes or even comes on for that matter. There isn't a Check Engine Light on, or any indication that something is wrong, the car simply starts and shuts off immediately. I have two keys, neither of them work.

So far I have tried to put the ignition in the on position, let it sit for 10 minutes and turn it off for 5 seconds and try to start it. That didn't work, so I tried to do that 3 times over, but one thing was missing from the instructions that I followed: the part where the security light blinks or turns off after 10 minutes.

Also, Does anyone know which anti-theft system this vehicle has?

Have replaced everything that it calls to replace and now runs like a top just at idling for a while it just dies i am up stuck have sure track system at the shop and still can not figure. Out this issue plz help asap thanx

When it is cold, vehicle starts but when put in reverse it stalls. After warm up, 2-5 min, no problem. If put in drive when started, , no problem. No mechanic knows what the problem is. Help!

i have a 2005 Chevy trailblazer with 113000 miles and my mechanic told me that my trailblazer have a Bad valve and misfire #3 . is a recall on this suv ?

I have a 2005 Chevrolet Trailblazer Ext Lt 4wd; I have a problem with my
4wd engaging it seems, when I put my suv in 2hi, it makes loud grinding sounds when it goes in to gear and feels like it is netural will not drive also does the same in A4WD. It would drive in 4wdHi with no grinding noises or nothing but now it is starting to do the same thing in 4wdHi; last night it locked up on the highway and when into park mode at 60 miles while driving all of sudden. Was able to safely get it to the side. Was able to get it home in 4wdHi, but now it can only be driven in 4wdHi or 4Lo but grinding can be heard and now the rear differential locks up and grinding is heard and feels like the brakes are engaged in the rear. So I am thinking the rear differential is shot completely.
Is there anything else I should be looking at also.
