#15 of 27 Check Gauges Light by mekaj

Mar 04, 2009 (1:26 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?

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?

I would get a 2nd opinion before forking over that kind of money to fix it

Oct 26, 2009 (5:52 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?

#21 of 27 4 wd abs service lights by dkredmond

Feb 13, 2010 (2:27 pm)

Hi
Yesterday while driving, the following light lit up on my dash cluster.
service 4 wd, abs, brake.
At the same time my fan stopped blowing out air into the cabin,
does anyone know if these are related and just bad luck having multiple problems at the same time.
Thanks

#23 of 27 ABS, Brake error lights and ac fan not working. by dbunton

Jul 16, 2010 (3:20 pm)

I have a weird one. I have an 04 Trailblazer and when I turn the air on speed 1-4 the fan does not work and my dash board gets both the yellow ABS and red brake lights. If I turn the air on speed 5 the fan does work and the error lights go away. If I turn the air off I do not get any error messages, thus I only get error lights when using air spreeds 1-4. Please advise?
 
Thanks

I don't have a wiring diagram, but it could be a problem with the fan speed resistor board. On the highest speed the board is mostly bypassed and the fan is connected to full voltage via a relay. If the board had a short circuit and it's in a circuit with the other warning lights then it could cause a problem like you describe.
