i have a noise in the front end of my 2003 Chevy trailblazer i changed the CV joint half axle and still have the noise i see a little movement in the CV joint at the end but the disconnect actuator could the vibration be coming from the actuator ? It seems to shift OK from 2H TO AWD AND 4H and vibrates in all settings.
I will be changing this part asap.. this vehicle has everything original.. not one part has been changed until I purchased it.. I recently changed the fuel filter, battery and computer.. if your car doesn't start and only the gauges come on. 10-10 it's your computer.. I can get in detail if someone has that problem
Front bumper is loose, how many brackets are there and where are they located?
I used the air one time and now there is a rattle, what could it be, fan clutch was replaced, new belts, dont know about this
Fan clutch has been diagnised but hasn't caused a problem running until today. Want to know if that could be the cause of my check engine light blinking and engine running very rough.
I have a 2003 Chevy trailblazer. Over some time now I noticed the temperature gauge is below 210. I done some research and read that my temperature sensor could possibly have gone bad. Would that also cause my check engine light to go on as well?
My TB acts like it wants to stall out when sitting in heavy traffic or at a stop light. I want to know if there's any way to bumo up the idle rpm so I won't have this nagging problem anymore. The dealership has told me there's nothing they can do because it's all computer controlled but I'm not convinced without someone hooking up a computer scanner and charge me $500 for the service. I'm frustrated and desperately need help here.
