Ok, so here's What I've done to the truck (yah, before I describe the problem) ;-) Problem was with the Avvy before I performed these things too...
1) I had to replace the dash gauges due to the known issue with the gauge cluster going out at random times. The entire gauge cluster would only come on when it felt like it.
2) after replacing the instrument cluster I noticed that the "flickering" problem was still there, and I had somewhat low voltage at times under load (see below too) (A/C on, High Beams on) so I figure the alternator was on it's way out, or at least the voltage regulator within the Alternator.
So I replaced the alternator, 135amp unit 12oclock connector.
3) I replaced the drive belt along with the Alt too.
4) Battery is brand new Sears Die hard gold 724CCA, 'bout a month maybe month and a half old.
So now this problem is still there. When I put on my lights at nigh they kinda flicker a bit, dash lights/console lights/heated seat and window switch lights.... it's noticable, but just a bit noticeable... it's for sure a flicker, the kids see it too ;-(
If I try to put two windows down at the same time, any two windows, and keep both switches engaged after the windows go up or down, I can watch the volt meter drop to about zero and then all kinds of bells ring and dinging occurs until I let off of the swtich. This happens whether or not I have a high load on the truck... so if I have all lights/AC/radio/etc turned off, and hold two window switches up or down I can re-create this condition.
Is there a separate voltage regulator in the truck other than within the alternator?
anyone see this danged problem before? It's so annoying and I'm concerned that it's just the tip of the iceberg.
avvy is a 2003 ZL1 package loaded with all the toys... the only brand new vehicle I've ever bought and I just love my Avvy, but this problem is making it hard for me to convince the wife that the Avvy is still dependable ;-(
any help would be greatly apreaciated!
thanks all!
