I have a 1998 tahoe that just recently started to have lights flicker when there on. noticed both headlights and dash lights doing this.

Sounds like a problem in the alternator.
The voltage regulator is insidethe alternator and controls how much it puts out.
It can be cycling high and low, causing the flickering, that is if it is steady intervals. Sort of up, down, up, down,...
It it is just willy nilly, could be a loose wire somewhere.

Ya, sounds like alernator.
Either that or a faulty headlight switch.

2001 Tahoe smoking and electrical problem

Unread post by Vqlakr » Fri Oct 25, 2013 2:56 pm

My Tahoe was having a problem so I took it in and shop
said it needed a major tune up. 3 days after it got tuned up
it started to stall again. Same shop said it needed fuel
pump. Here we are 2 weeks after replacing fuel pump and
I'm having problems again. I started Tahoe this morning
and when I put it in drive it idled really low and started to
smoke (white smoke) from front driver side. Also the
electrical was going crazy. Lights radio and front and back
wipers going on and off. under the hood smelled like
burning plastic. So before I take it to this shop for a 3rd
time I would greatly appreciate any comments. My Tahoe
has been in great condition for almost 13 years and I'm
hoping it can give me a few more

hard to say anything about this one. If you smell something burning from the hood did you open the hood and see if you could see anything? With all the electrical things going nuts I would look at some thing related to the body control module. I wouldn't think that it could be related to the other work that you had done but crazier things have happened.
