#12 of 20 Check gauges light, low temperature, engine racing by rnorris1 Jan 02, 2008 (6:18 am)
Hi. I have an '02 Trailblazer. I have had lots of minor problems with it since we purchased it new in '02. But, never anything major. About 1 month ago I was in line picking my children up at school. The check gauges light came on. The engine was reving. The temperature gauge had dropped to 100. I left the school and it continued for several miles. I had to stop at the red light beside my house. I had my foot on the brake but, the car was still trying to go. Before, I got home it stopped. But, it has done these several times since then. Any ideas what might be going on with my car?
#13 of 20 Several warning lights by alex_g_2007 Feb 11, 2008 (12:28 pm)
I have an 03 TB with several warning lights. The service engine light sometimes goes on and out then all of my gauges move to the far left then the airbag, abs, seatbelt, and, parking brake go on at once and the gear selection line under the shifter is gone but i can still feel for the gears.The car makes that warning beep whenever the doors are open. then within a few seconds it stops and goes back to normal Any suggestions?

Replying to: alex_g_2007 (Feb 11, 2008 12:28 pm) i had similar problemon 02, check engine light would go off and on, seat belt light ,ABS light similar, and others and Crusie control sometimes not work, all intermittent. As usual the Chev dealer had trouble fixing it. First visit they said it was a bad ground and changed out a grd bolt, did not fix, Second visit changed a camshaft actuator, did not fix, Third time they wanted to change out the ABS module($800) and that's when i told them to change out anything they want but i couldn't understand how that could make the Seat belt light and Cruise control malfunction and if that did not fix it, I was not paying anymore, The service mgr saw me and asked what the problem was , and he told me not to worry,that he would get it fixed. I think they called Detroit and bottom line which will not help you is it got fixed no chg and i never found out what they did. Sorry.   Previous visit for electrical problem, the four way flasher came on when i used the directional signal, same issue, four visits before i researched it myself and told them there was a 238,000 vehicle recall for the same problem on 03(same switch). Bottom line is their electrical components stink and they flounder at pinpointing the issues, Other than electrical problems and there have been others, have had pretty good luck with my vehicle .
#15 of 20 Check Gauges Light by mekaj Mar 04, 2009 (12:26 pm)
I own a 2002 Chevy Trailblazer LS. I have had to replace my fan clutch about 2 years ago and my truck does have that clicking noise whenever I start it up in the morning but whenever it warms up it does stop. New problem, on my way to work this am, my check gauges light came on and then the oil pressure gauge kept going from 80 to 0 whenever I came to a stop. What could this possibly be?

#16 of 20 engine lights on or off by hjhildo Mar 06, 2009 (10:14 am)
The lights go on sometimes and off whenever. Took to dealer and was told misfire in cylinder. Need a repair for $3600.00 to a 27000 mi 2006 TB. Of course, they found it right after the warranty goes off. Was told they are having problems with them. This is obviously a TB problem and not mine. I service the vehicle constantly. Had electrical problems, module, air leaking because poor manufacturing, etc. Do I have to replace the head like they think I do or what do you do for a misfire in the 6th cylinder?

my 2003 tb with 4.2 six 90k has a check engine light said it was a temp sensor had it replaced and code reset. after 200 miles or abouts it comes back on with same code. just came back from a 1500 mile trip.it ran great even with check light got 23mpg at 75mph with air. just replaced water pump as it had a wobble not leaking. now i'm told it might be theremostat, yet it is working find.feel like they are just changing parts?

Replying to: prestonschevy (Sep 25, 2009 10:41 pm) I would get a 2nd opinion before forking over that kind of money to fix it
#20 of 20 Rpm issue and SUV wont accel correctly by heezyjos Oct 26, 2009 (4:52 pm)
my suv when i drive it i willl hit the gas pedal the rpm's will go up but the car seems as if its idoling like im revving the engine in drive is the best way to describe it and i cant get the car to go over 40mph it seems. autozone checked my check engine lite and they advised that there was a problem with the coolant sensor however would this causethis type of problem. i also just had the battery replaced and the battery is only a few weeks old we checked the connection on the battery an they were not tight but autozone tightened them for me and it is still doing the same thing. any ideas on what the problem could be?
