#159 of 171 02 Trailblazer dim lights, fast turn signal
Dec 27, 2011 (6:51 pm)
First noticed that the left turn signal was doing double time which normally means a bulb out. Checked all bulbs and all are working. When I jiggled the high beam switch (same as turn signal) it would blink normally. Then next time start double time again. After a while when the high beam is on the left turn signal will blink once then stop. (Really not sure if related or not but the green arrow indicator on the dash stays dimly lit all the time. May be just picking up light from bulb behind meter cluster?)
Also noticed that ALL front lights on the driver side are more dim than passenger side (high and low beam and turn signal and running light). It is very noticeable when driving. Not sure if the two situations are related.
Here is what I have tried so far:
Swapped the real tail light circuit boards. No change.
Swapped the front head light assemblies. The one from the passenger side that had been bright became dim on the driver side and the driver side assembly became bright on the passenger side. So I am assuming it is not the lights, connections etc. as the problem stayed on the driver side even though the parts were changed.
Checked voltage on both front sides. Reading just over 14 volts (same both sides).
I swapped the high beam relay in the fuse box with another relay. No change.
The turn signal relay uses the same relay for both right and left and em flashers (which flash normal speed by the way) so I don't think it is bad.
My only thought now is that the turn signal switch is bad but a new one is $100+ so don't want to buy one if not needed. It may be causing the fast blinking, but not sure about the dim lights. Anyone have anything like this happen? I have read about some crazy electrical issues with the TB but nothing like this.

Ok more info for post 159 above- after checking today and noticing that the high beam light flashed when the turn signal was on (I could not imagine an electrical system where the high beam would be on the same circuit as the turn signal). Anyway, I was going to take the fuse box apart to see if there was anything melted or shorted out underneath and noticed that all the bolts were already loose (hand loose). I tightened them all up and PRESTO all the problems went away!! So after several hours of messing around I lucked into the fix. I think the dealer left the screws loose a while back they had to do some electrical work. The issues did not start right away so I did not make the connection (no pun intended). p.s. This vehicle is trouble waiting to happen! I would sell it but it's not mine!!

My lights have been staying on and draining my battery. I have a 2003 trailblazer. I have replaced my relay for the dimmers. We haven't ruled out #46 relay yet will be doing that tonight. I am almost positive it is not #46. Has anyone had this problem or have any other ideas of what it might be?

After your vehicle is turned off or what? The TB's I've seen and it's been many, #46 has been stuck in the on position when the battery is being drained. If you're talking about the daytime running lights, there is an off switch. OR you could install a DRL killer.

Yes, after I turn the car off my daytime lights stay on and drain my battery. I went to buy #46 and it is $34.00 with no refund. I want to rule out all the possibilities before I buy this part and it be something else. Thinking it could be sensor or somethng in the wiring but not for sure. Where is the off switch? The different light settings switch inside the car does not work when I try to turn them off.

Some years have an off setting on the dial, some don't. Mine does 03', turn the switch all the way to the left then try twisting a little bit more. Hard to describe, but it's kind of like a spring loaded switch. Twist the dial to the left past the point where it would normally just sit.
Have you tried switching relay #45 with 46 to see if it turns off? If I were you I'd buy that relay anyway and have it just in case ($35 is a good price). In due time it will need to be replaced. Mine has already gone out and I still keep a spare. Also, is your DRL sensor at the windshield visiable or has it fallen into the dash (happened to me). If all else, look up DRL killer for trailblazers if your model doesn't have an off switch for the lights.

I have an '02 Trailblazer LS. Yesterday my driveside low-beam light was working, but one time it shorted out for a couple of seconds, then came back on. Today the low-beam light is out, as well as the high-beam light. Neither light will come on. I went to Autozone, replaced the low-beam bulb, and still neither will come on. I checked the fuses, and both were good. I tried switching #45 & #46, and still didn't work. Could someone please help me out! I plan on getting it fixed sometime tomorrow. I feel that it might be something basic. Again, both high & low beam lights will not come on. I took of the grille, and light about 20 minutes, replaced the bulb. Checked the fuses. Nothin'

Did you check for voltage at the connector when the lights are on? That's step 1. How did the connectors look?

I have a 2005 and mine was doing the same thing in JUly 11. I sure pissed off alot of people to.LOL But it was the only way home. I had to finally take mine to the dealership not once but twice. They fixed At the tune of 350 or so. I still have problems with it flickering every now and then but I haven't took it back. I've had lots of problems with this vehicle and I'm ready to get rid of it. Gas gauge went. wiper on back not working after the front quit working. Cd player not working. now none of the locks wanna work half the time and half time cant get rear door to even open. It has a mind of it's own. Also the transmikssion done started slipping. Never again will I buy a trailblazer.
