    C0374 code and crowhopping in A4wd?

    Okay, I am stuck here. Replaced most common failure items, but still get a C0374 code. All is good in 2WD. If I switch to 4WD Auto, when I corner next, "Service 4WD" lights with code C0374. If I turn sharply, it starts crazy crowhopping as if it was in 4WD and not A4WD. It then stays stuck in...

    Lost mileage and gear indicator in instrument panel cluster

    After I replaced two more stepper motors in my cluster - which was strange because both were from the batch of "newer" steppers - the readout for mileage and gear indicator seemed to be a bit lazy afterwards. Every few weeks, it would take 30 seconds before they lit up. Every other gauge was...

    New vs reman brake calipers

    As most of you know, I am pretty anal about handling and brakes. When switching to my winter rims on our 04 Trailblazer LT, I noticed the pads were getting down a bit so I popped off the caliper and looked at the pads. The NAPA Adaptive One pads still had lots of wear left (about 20,000 km since...

    Resonator death rattle: what is the best aftermarket resonator?

    The insides of my resonator is rattling, and it is time for a replacement. I do NOT want to just delete it ... mostly because I am old and slow and all you damn kids should GET OFF MY LAWN. Basically, I do a lot of highway driving and do not want the slightest hint of drone. I am looking at the...

    Differential cover, bolts and gasket for 8-inch rear end

    There have been many posts asking about the rear diff cover, so I thought I would just address some of the questions in one new post based on recent experience. Aftermarket rear diff covers for the 8-inch rear end that comes on most short-wheelbase 4.2-litre Trailblazers and Envoys seem to be in...

    New 6x5 black wheels for Trailblazers

    I went from 16-inch to 17-inch winter tires (Michelin Latitude X-Ice Xi2) and wanted to get black rims to match my beloved American Racing black Trench wheels but if course they are no longer in production. Not wanting to settle for black steelies, I did some shopping around plus visited my...

    Coolant temp sensor doesn't screw all the way in

    I replaced my thermostat, rad hoses and ECT sensor last weekend. All went well until I tried removing the old ECT sensor. It snapped off at the head, leaving the body and threads inside the block. I finally got it out by drilling a hole in it and using what is laughingly referred to as an "easy...

    Which is the correct door lock actuator?

    My driver's door lock actuator is getting lazy in cold weather and I want to change it before I lock the truck someday and don't realize the driver's door is still unlocked. Research shows the AC Delco 11P4 is the correct actuator, or the Dorman 746-017. But now I am confused. Both say "w/o...

    NEW GM headlight relay (relay #46) GM part# 13506836

    GM has just released a fix for the 2006-07 recall involving some GMT360s. It is a new headlight driver module (HDM relay), GM part #13506836. It replaces part #15016745 which could allow the headlights to cut out if overheated. Our 07 Trailblazer was not recalled in Canada, and I cannot find...

    Tie rod ends and alignment

    I am interested in what others have done for wheel alignment after replacing tie rod ends. I did a lot of research and found most of what I read on the internet to be wrong. In many years of driving, I have found a couple of facts that I can trust: #1 - The human eyeball can be as precise as a...

    Headlight relay - counterfeit AC Delco being sold on Amazon?

    I replaced my headlight relay with a new AC Delco 15016745 relay from Amazon trying to chase my headlights flickering issue. I also replaced the alternator with a new AC Delco unit and added the "big three" wiring upgrade. Nothing so far has worked. What i did find is that the headlight relay...

    Replacing 4wd selector switch

    Yes, I am too stubborn to try the old site. Is there an easy way to replace the 4wd selector switch on a Trailblazer? I don't really relish taking the dash apart at minus 30 degrees just to get access to the back of the switch so I can depress the two prongs and pop the switch out the front...

    Scratching noise in B Pillar

    When coming to a stop, I can hear a scratching noise coming from behind me, just above head level, in the B Pillar. It sounds like a tiny cat scratching to get in to the house. (Best description I could think of.) I am not sure if it only makes this noise at slow speeds or while stopped, or if...

    Every Canadian should let Amazon know they are DISGUSTED with them right now

    I am literally sick to my stomach. http://www.cbc.ca/news/canada/toronto/paul-bernardo-amazon-ebook-1.3316621 Amazon published a book by Canada's worst serial rapist and murderer. This scum is going to profit while he relaxes in prison and laughs at how he has all the time in the world and...

    04 Trailblazer one of six must-have rides to escape the zombie apocalypse

    Not much of a surprise. It may not have mounted .50 calibre machine guns, zombie-shredding grills or smoke canister launchers, but it is fast and can outhandle many other SUVs on the road. This was a humor article for Canada's Globe and Mail newspaper, but it is obvious that some people took it...

    LED fog lights - wire in with factory lights?

    I have the factory fogs and want to improve on them with a pair of PIAA 530 fog lights mounted on my safari bar. They draw 3 watts each. At this low draw, it seems like it would be easiest to just splice them in to the factory wiring and use the existing switch for factory and PIAAs. I would...

    Replaced rear coils - can they be installed upside down?

    I noticed the rake on my 04 is much less than my wife's 07, and I wanted to try changing rear coils. I often drive many miles over bumpy northern roads with 600 pounds of shotgun targets in the rear, so it wouldn't surprise me if the rear coils were starting to sag a bit. I pretty much gave up...

    DJM adjustable versus Hotchkis rear sway bar

    As many of you know, I am pretty anal about handling and I am always seeking the most neutral-handling dynamics in any vehicle I own. I installed a Hotchkis rear bar two years ago and LOVE it. It really affected the handling in very significant - but also very subtle - ways. (By the way, if...
