SOURCE: 2002 Trailblazer blower not working

The blower motor resistor card is located under the glove box. You have to take the bottom panel from underneath the glove box out(be careful not to break the wire clip that holds the wires in place on that panel). Once you take the panel loose look in the back. You will see the blower motor. Behind the blower motor is the card. You will need a 9/32 for the panel and a 7/32 for the card. It is only 4 screws total to remove and 2 wire harness clips. It is about a 15 minute job. Good luck and hope this helps.  Auto Zone has the part for around $15.00 and will have the step by step instrutions for you also if you need it free of charge. I think the dealer charges $109.00 for this repair.

SOURCE: replace low beam headlight on 2003 chevy trailblazer

I just replaced the low-beam bulb on my 2003 Chevy Trailblazer. The grill just needs to be loosed slightly. Then, raise two L shaped brackets, one on each side. For the inside one, I needed to use a flathead screwdriver to get to it. The light assembly can then be pulled out. Remove the rubber cover and rotate the bulb one quarter turn left to release it. Pull out the bulb, replace with a new one ($11.50) from Advance Auto Parts, and reverse the process. Once I figured it out, took about 10 minutes total.

If you have automatic climate control, replace your blower control module, behind the glovebox.
If it's manual, replace blower motor resistor assembly, same location.

Whee are the spark plugs located on a 2003 chevy trailblazer


Underneath all the plastic on the top of the engine. Remove the plastic and remove each of the 6 coils, (2 bolts for each coil). Your plugs are under each coil. Use AC Delco 43-103's, TB's love these more than all others.
