Problems with a 04 trailblazer ticking and quit pulling

Has to do with the timing in the monitoring period, Bosch isn't quite within the specs for our vehicle. Hopefully you used a different brand 02 sensor? Other problems could be low fuel pressure, faulty injectors or an intake leak. Check your intake bolts, our intake is plastic and the bolts DO come loose often. Re-tighten, erase the code and see if that works.

take to a parts store, advance auto, etc., have them pull up trouble shooting codes from ECM, these codes , could be more than one, will pin point your problems. when engine light stays on , its storing codes, and these need addressed asap. as far as that ticking noise, get out might be a bomb, just kidding

if one window need to test power to the switch if power than will have to pull door panel to access the motor/regulator to test motor and lines for power as will as window tracking which may cause binding and or motor burn up

There's 9 screws in the plastic piece that surrounds the instrument cluster and the lower knee guard, remove those screws and pull the plastic trim away from the dash, disconnect the switches on the left side as you pull outward. Then there's 4 screws that hold the actual instrument cluster in place, remove those and pull the cluster out, unplug the grey plug in the back of the instrument cluster and your done. You may need to set your parking brake and put your transmission in 1st gear of you have a column shifter model.

Pull the HVAC B fuse located inside the truck for 5 min and then place it back in.The short time the fuse is out and placed back in, the control module will attempt to recalibrate all the actuators, by running them CW and CCW until they hit their stops. Then the control module remembers those positions and tries to not slam the actuators into the endpoints with vigor, to avoid breaking them.
Naturally, they messed up the programming, and the recalibration process is what breaks most of them after a battery discharge or swap.
When a recalibration fails, the control module just quits using that actuator and it's frozen in position. All the other ones are OK, though. What some Trailblazer owners do as a temporary solution, is to start the recalibration process with the fuse pull. Watch the actuator until it's in exactly one position that is useful, and then quick like a bunny yank the connector to that one actuator. It might be frozen in position, but you can choose a good one. The same trick is a lot less useful with temp actuators.
Thank you for using Fixya and might be a dead airflow mode actuator. Common problem.http://forums.trailvoy.com/attachment.php?attachmentid=505&d=1208022408

Check the fuse box. There should be something that tells what amp fuse #22 is. You may have a spare fuse in the box. Worse case scenario, pull a fuse of the same power from something that you don't need and use it til you get the key out. If the fuse keeps giving problems that indicates you need to get something checked out. DO NOT put in a larger amp fuse to get by. Fuses are there for a reason. It is not worth burning a Trailblazer up because of a $3.00 fuse.

it has to relearn the idle it may take about 40mins of driving to do this

Hello;
Can't show you exactly, but is easy to take the grill out and change lamps while it is out! Grill has clips, you just have to un-clip it, pull two tabs on each side on the top and the whole thing comes out! (20 Minutes)
