Re: lights flicker! Nope no system, stock monsoon. Its like a split second flicker occurring occassionally while driving, like power is cutting for a second to headlights.

Re: lights flicker! Join the club....my 'bird did it the second day I had it. I've noticed it maybe a half-a-dozen times in the three years I've owned it. At first I thought maybe I just was noticing myself blinking...I mentioned it to my dealer, and they just kind of "didn't hear it" when I said it....

Re: lights flicker! I will tell you what it is----
You prolly wont believe this but try this for yourself if you dont believe. When the motor is cold and you start it, you will here the air pump run(electric), after it shuts off (high pitch whine) have your headlights aimed at a wall or the garage door. Then hit the throttle a couple of times to get the pump to turn back on when it does the lights will flicker.
The reason this does this is because the motor turning on draws alot of juice and draws the electrical system down temporarily. Causing the lights to "flicker"
I searched like you guys did and I found this one day while working on a differant problem under the car with the lights on.
Hope I explained it so you guys got it. <img border="0" title="" alt="[Big Grin]" src="gr_grin.gif" />
Have fun, Dave

Re: lights flicker! Happens to my '02 Z in the first few minutes after i turn it on. When I'm in gear and then step on the clutch to take it out of gear when coming to a light or stop sign, the dim real quick. Guess it's just one of those things we have to deal with. <img border="0" title="" alt="[Roll Eyes]" src="images/icons/rolleyes.gif" />

This is normal on all GM vehicles. Kinda similar to when your A/C compressor engages and the lights should dim a little temporarily.

Re: lights flicker! You can all but eliminate this problem by simply running a good 0/1 gauge wire from the engine block to Frame, Negative battery post to chassis, and Battery to alternator wire. Also, an upgraded 8 ga. wire to the fuse box. The guys with big systems in their cars upgrade these wires and it helps tremendously. Pretty easy and cheap too.

Re: lights flicker! I believe they arent talking about the lights dimming when something comes on. My 01 does it and my girls 02 does it too. You can drive down the road at night as watch the lights do a very mild strobe effect. Its very faint when it dims, some more than others. You can look closely at the gauges and they dim also. Its not the common dim when something comes on, but it flickers rapidly. I have yet to figure it out, but its VERY ANNOYING!!!!!
Re: lights flicker! mine did it the night i was driving it home from the dealer when she was brand new. i've always wondered this, but never think to reasearch it at the right time. i do like that bigger cables thing though. and, call me dumb, but what exactly does that little pump do? i hear it on the car when i start it up and am standing outside it? thanx.
