Ended up having the dealership do mine, ran out of time (I needed a inspection sticker). When I asked them, they said that there were only two latches to undo in order to get the assembly out.

I had the same problem. The belt was glazed over and the dealer replaced it under warranty. Another cause could be the idler pully bearings are going out. I'd replace the belt and see what happens.

2002 Trailblazer Diagnostic Trouble Codes by bxjohns

I was wondering if you are able to retrieve the trouble codes on the trailblazer without a scanning tool. On my previous automobiles it was possible through the radio controls. I may have problems with the transmission and cooling fan clutch, hoping to be able to get as much information as I can before taking it in for service.
 
Thanks for any response,
KJ

Trailblazer 3rd Brake light by myfire101

I have an '02 Trailblazer. My 3rd brake light is out and we can't figure out how to replace it. Everytime I go to the dealership and ask them, they say I don't want to know the price to fix it. My husband is extremely handy and is willing to fix it himself, but he doesn't know where to start. Is in all one piece? Is it individual bulbs inside??? How do you get the cover off?

O2 TB were notorious for rear light bulbs continuously going out. Eventually I had to replace the entire housing to correct the problem. Have not had the same occurrence since.
 
Replacing a bulb or the entire light housing lens assemblies are very easy.
 
1) Raise up the back end tailgate door.
 
2) Once the gate is open and your looking at the tail light lens you'll see two
screws that hold the housing(s) to the body fender. Remove the two screws to simply detach the housing from the car. As you detach and pull the housing away from the vehicle you'll notice that the housing is tethered to the car via a cable with a plug on the end. Detach the plug from the housing. Now your light assembly lens assembly is free from the vehicle.
 
3) Notice the pins on the back of the lens housing where you detached the cable.
That entire assembly is held in place by 4 small screws. If your just replacing burned out light(s) you'll need to remove those screws and take that piece off the back of the housing to get access to the lights for removal. The bulbs are in individual sockets. Simply pull them out and replace.
 
4) If you decide to replace the entire housing with a new one, which I highly recommend, the new housing will come with new bulbs.
 
Hope this helps your situation.

My driver side power seats quit working. Well, not altogether, but it will not move forward/backward. Anyone have this problem and know how to correct it?

On the 3rd brake light, aka Center High Mounted Stop Light "CHMSL" it is known to fail. You have to replace the whole light assembly because it is sealed and not repairable. It has a long neon tube and electronic module inside to power it, no way to open it without destroying it because of the way it's glued together. The '02s and '03s came with a neon CHMSL. It is no longer available. Dealer replacement is with the newer type LED CHMSL from '04+. Supposedly the whole top trim molding piece the light mounts to also has to be replaced and painted to match the vehicle, in order to upgrade to the newer type LED light, so that's probably why they don't want to tell you how much it will cost. Or, maybe find one from an '02-'03 in a salvage yard or on eBay. If you can find a good used old type CHMSL from an '02 or '03 that would be the easiest cheapest fix. To get to it, you raise the rear window glass and take out two screws. But before you do that, raise the whole liftgate, remove two push pins from the headliner at the rear, there will be a smaller wire from the top of the liftgate to a rubber grommet, on the other side of the grommet above the headliner is the plug. Unplug it and pull the grommet out with the wire and connector, then lower the liftgate, raise the window, and remove the CHMSL. Do not raise the liftgate with the window open! Good Luck!

tubing rust throughs by trapjack4

Has anyone had a problem with various tubing rusting through? Have a 03 Trailblazer LT that has had power steering tubing rust through which was partially compensated by Chevy. Since then I have had tubing that supplied heat to the back vents rust through. These lines I had bypassed so that I at least have heat to the defroster. Also the AC tubing has rusted through so I have no AC and it looks like the tubing for the transmission cooler is pretty rusty and I don't know how much I can trust it. Although it drives nice I've been pretty disappointed with this vehicle considering all the above problems plus how fast it goes through brakes and rotors. Two sets so far. About ready to ditch it rather than make more repairs. Only have about 75,000 miles on it.

Can't speak about the rusting tubes, but everyone I talk to has nothing but good things to say about the brake life on the TB. Ours has 64K on the original brakes and the fronts are only worn about 60%.
