#1 of 20 yellow engine warning lights by nasterizer Oct 18, 2006 (5:05 pm)
I recently purchased a 2002 LTZ Trailblazer. I love the car. When i purchased the car it had like a ticking sound when u would start her up but only for like 3 minutes then it would go away. The original owner said that it was from the fan clutch and it was nothing to worry about. H e had even purchased a used clutch but never got around to installing it. two days later as i was driving a yellow engine light came on. i got worried. i kept driving. Then another one came on but with an arrow pointing down in the middle of the engine. I went to a local mechanic and he cleared the alerts. 20 minutes later they came on again. but first the engine light comes on then later on the second one with arrow in the middle comes on. Is this from the fan clutch?? What do these alerts mean?? Im really worried that smthg is going to fail or the car is going to die out on me. All the other guages are stable and i didnt notice any difference in performance. Please anyone help me. Replies to this message: jworkman (Mar 29, 2007 6:36 pm)

Replying to: nasterizer (Oct 18, 2006 5:05 pm) Find a mechanic (or go to a GM dealership) that has a TECH 2 computer analyzer....they will be able to pull any codes that are setting those lights off, and not just "turn off the lights".

Both brake warning lights, service engine soon light come off an on intermittently. Airbag warning light also would come off and on but is ok for couple of weeks. Also cruise does not work, again intermittently. Once a month ago, the clock in radio had to be reset.   Dealer changed camshaft indicator, did not fix, then installed new grounding bolts, and says all terminals were cleaned,, now wants to change ABS module, which i don't think is the problem, Any clue?

#10 of 20 ABS, Park Brake & serv. eng. soon lights by bridgetm Dec 27, 2007 (9:57 am)
Replying to: ever3 (May 06, 2007 5:38 am) I have a 2002 TB and was driving when suddenly, the Anti-lock Brake System, Emergency Park Brake, and Service Engine Soon lights come on at the same time. I immediately pulled off the street into a parking lot. Checked to make sure the park brake was not up, put the car into "Park" and tried to proceed. When I tried to push the accelerator, it would not go. I had to push almost to the floor and it barely went. So I put it in park again, turned off the ignition (or so I thought) and the key would not come out. The engine wasn't running, but the car still had power...It was like it was in Accessessory mode. Lights worked, radio, everything....the key would not come out, nor would it start. We tried disconnecting the battery cables leaving it off for a little while to try & clear whatever error messages were present, but it did not work either. We tried to jump start it from another vehicle...not successful! If anyone has ANY recommendations or have experienced this, PLEASE share!!
