This is actually an easy swap out. Remove the electrical connection, remove the retaining bolt and pull out old one. I believe the sensor is located in the front passenger side of the engine on this particular model.

SOURCE: I have a 2002 Chevy Trailblazer. Just replaced

If you unhooked battery it will need to relearn its idle position, should help if you clean throttle blade edge and body of carbon so proper amount of idle air can enter engine.

How do you fix the cable for a power window on a 02 chevy trailblazer? The cable is good just got tangled up.


these are bad units. do yourself a favor and buy a wjole new regulator. they are cheap on eBay and parts stores. less labor to pull and replace than to remove repair and reinstall. it is 8 and they die about 10, those GM cable units are junk at an earlier age.

Im trying to dx my alternator problem, i want to check the fuse first where would i find that.i looked in the manuel but theres's not a fuse labeled alternator fuse(chevy trailblazer 2002).


That's because there isn't any. Use a voltmeter and measure the voltage on your battery, then start the car up, if the voltage doesn't move or goes down, replace the alternator. A normal voltage should be 12-12.5 Volts with car off and 13.5-14 Volts with the car running. Have a nice day!
