SOURCE: i have 2005 chevy trailblazer heater wont work,

Sounds like your water pump is going out or your thermostat is stuck. Check the thermostat first and make sure it is not frozen in the clsed position.

Do you know if the plugs were changed, a bad or broken plug will also cause rough idle and slow acceleration?

SOURCE: Throttle Problem

Well 2002 will be port injected,so the throttle body only adjust air flow.Try cleaning Mass Air Flow Sensor and replacing your fuel filter.Make sure that your air filter is clean.If you havn't had a tune up in 100,000 miles then it's time.It could be the TPS ,but would try the others first.Well hope this helps,and good luck.

Hi:
Your Brake light switch is mounted up near the top of the brake pedal arm. it is held inplace with a metal pin & a clip, as well as a small electrical connector. Basically, you need to unplug the connector, remove the clip, and pull out the pin that holds the assembly in place.

Common problem on the 03-06 Trailblazer instrument clusters for the fuel gauge to go out. It's usually caused by one of two main problems, either the stepper motor on the cluster's circuit board is going out or the sending unit on the fuel pump is going out. Check out this blog post about the problem - Trailblazer fuel gauge problems

Why wont my 2005 chevy trailblazer run correctly after a battery change?


Because the computer was reset after battery change, and you probably need to have the throttle body cleaned. It grimes up often and needs to be cleaned every 10 - 15K miles.

My 02 chevy trailblazer's rpm fluxchuates when


Many of the 6 cyl. engines are prone to carbon build-up in the throttle body. If this is the case, it is best to clean it off the car and is fairly easy to do. Remove the snorkel, 1 electric fitting on the throttle body (a little tricky) and one vacuum line on tb as well. Four bolts remove the tb from the engine and the throttle body can be cleaned with throttle body cleaner from any auto supply store. An o-ring attaches the tb to the engine so that you will not destroy a gasket during the repair. Pretty easy and should take less than 1 hour, but be careful of sharp edges in the throttle body.

With temperature related problems, check your intake manifold bolts for tightness. Our intakes are plastic and have a tendency to become loose, causing vacuum leaks. When it warms up, the plastic intake will expand sealing any leaks. But when it's cold, will contract, causing leaks. Easiest to check are cylinder #5 & 6 near the fire wall.

Also, clean your throttle body, a dirty throttle body will cause idle problems, especially in TB's because we don't have a true PCV valve, so gets dirty which causes sticking of the butterfly.

How to clean throttle body on 2002 chevy trail blazer. Step by step instructions if possible. Thanks so much


Instructions for doing it without removing the throttle body.

1. Disonnect the battery....very important so your stepper motor isn't ruined when moving the butterfly.
2. Remove the plastic resonator on the top of the engine (The black piece that says 4200 on it)
3. Remove the large rubber hose from the throttle body.
4. Clean away, with throttle body cleaner or Seafoam, I just use the blue shop towels to clean in there. Could use a plastic bristle brush also for more elbow grease. Be very careful, as the butterfly will cut you very easily, very sharp edges. Make sure you get all the gunk out of there, including any edges of gunk that may have formed, preventing the butterfly from opening and closing properly. Needs to be nice and shiny.
5. Hook the resonator and hoses back up, don't forget the little pcv hose on the front right corner of it.
6. Hook the battery back up and drive around for 20 minutes or so with all accesories OFF. The computer will relearn a properly functioning throttle body at that point.
7. Enjoy a little bettery gas mileage and horsepower.

As far as the injector cleane....Buy a $10 can of Seafoam, that will clean the injectors. Look on Youtube on how it works, good stuff.
