Question about 2004 Chevrolet TrailBlazer

1 Answer

We have an 04 Trailblazer that won't start. When

We have an 04 Trailblazer that won't start. When you try to start it, the dash lights up and the speedometer freeks out like you're revving it. It won't try to crank or roll over. We had it towed and found out it won't go into neutral. We had a friend run a diagnostic check and there weren't any codes. So now we're trying to find out all the possibles and we don't know where the neutral safety switch is or what it looks like. Help please!

Well my friend, my first opinion would be to have your ECM checked out. You might know the slang name of it "the brain" and it runs your vehicle. Now if it malfunctioned/went bad, it won't be able to give you any codes. I would suggest starting there. That could be why your having trouble with your neutral saftey switch also. Good Luck.

Now my 04 Trailblazer started this morning but no gauges and no warning lights in the cluster. OMG


This is a common problem. They had a bad set of motors that were used for the dials. It is an easy fix an several companies sell replacements. Or you can replace the dash cluster itself.

Look for any lights on the dash when this happens. If you see a light that says security, this is the sign of the problem.

My inlaws' 2004 buick rendezvouz: the dash lights don't come on. Dealer says no dash lights were installed on that model. Chris


The dealer is blowing smoke up your tailpipe. I couldn't find a manual for the '04, but the '03 and '05 have identical controls for the dash lights, so it's a very good bet the the '04 is the same. Here's a link to the manual for the '05 -- you will find the dash light control on page 3-16.

There's 9 screws in the plastic piece that surrounds the instrument cluster and the lower knee guard, remove those screws and pull the plastic trim away from the dash, disconnect the switches on the left side as you pull outward. Then there's 4 screws that hold the actual instrument cluster in place, remove those and pull the cluster out, unplug the grey plug in the back of the instrument cluster and your done. You may need to set your parking brake and put your transmission in 1st gear of you have a column shifter model.

Sounds like a short in the wiring. Was the body damage in an area where the wiring could have been damaged also? You should take it back to the repair shop and tell them what is happening.

Same issue no radio,windows, locks but dash board electric works


Try unhooking the battery, turn key on, leave door open, then connect battery, start engine immediately. The battery saver module thinks it's saving your power!!

Hmmmm, from what u say, sounds like everything is ok, but,Bad battery can run lights, radio, but trying to start, will make clicking noise. U jumped it to start, and it did, another sign of bad battery. How are the connections at battery? Tight and clean? No corrosion? Check wire to starter also to make sure it's ok. If all connections are clean and tight, I would recommend removing the battery, take to parts store for free check to see condition of battery (low charge, or if it's shot). If u jump start it, u can also have them check the alternator too (free). U indicate dash gauge @ 14, that should be good. Battery usually has a date 'thingy' on it that u peel off #'s to indicate when battery was purchased, does yours have the 'thingy?'
