I thought this would fit better here rather than in the 2000+ thread, since it is the 5.7 square body style. I have a 2000 Z71 Tahoe. 150,000 ish miles. Bought it July of 2018. Clean carfax. Drove fine for about a year then the electrical zombies and gremlins surfaced. Keep in mind I have done nothing to it or made any modifications, other than replacing the fuel pump (ac delco) and some of the front end components. They were ok but just wanted to have a little new stuff in those spots. And replaced the wheels. Originals were awful. lol.
Here goes.......(keep in mind, I am a moron, so hope this all makes sense)
Starting in June of this year 2019
1. One of my employees noticed, leaving work one day, that when I hit the brakes my reverse lights also come on. Who needs reverse lights anyway so I just yanked them out.
2. Driver side window started not rolling down at will. Sometimes yes, sometimes no. I replaced the power module thing under the window and lock control panel. Works better, but still doesn't work sometimes.
3. Noticed one night, while trying to use my brake lights while backing up at the house that while in reverse the tail lights work but not the brake lights. Except the 3rd one up top.
4. Then once again an employee noticed that I have the 3rd top brake light, but not the other 2. Even while in drive or in park. Nothing. Tried to see if they would work as the hazards. Hazard button didn't work. I noticed while pressing it up and down, that they would come on if I pressed the button down and to the left. So I shoved a small *** of tape in there to hold it over temporarily.
5. About a week later, I drove my son to football practice and shut of the tahoe for about 5 mins then tried to fire up and go home. It would turn over and start to fire up then die. Over and Over. Called a tow truck. towed it back to my business, rolled it off and hopped in and it fired right up fine. Worked for several weeks fine. Employee noticed the crankshaft position sensor was loose and the wires to it were bare and exposed. He cleaned it up, taped it and all good for now.
6. couple weeks later while again driving to football practice one morning, I hit the blinker to turn right and the blower motor for the ac shut off. I jiggled the ac controls and was able to get it to come back on.
7. I replaced the entire blinker switch, which controls the hazards also. Perfect......for about a week.
8. Then, just yesterday I drove to work fine. About 30 mins later I had to run home.....When I hit the key everything lit up then went dark, dead. Nothing. I turned the key back off and in the off position the flasher relay behind the brake pedal started buzzing loud. Turn the key on and it stops. No lights or accessories. No Start . Ordered a relay (acdelco) and put it in and hit the key. Same thing first try. Second try I got lights and accessories back and no relay buzzing. Employee told me the computer may be resetting so leave it in on position for about 60 seconds. I did and it started right up fine. That was yesterday.
9. Today........while running some errands I felt a weird blip in the tahoe. On interstate doing about 65mph. Dash lights flickered and I felt the truck loose power for about half a second. Maybe not even that long. It caught my attention big time so I moved over to the right lane. Then BAM!!! The tahoe goes 100% totally dark, dead. Electrically and mechanically. I was able to bump the shifter to neutral and exit. Once stopped I hit the key and it started then immediately died just like a month or so ago at football practice. 2nd time I tried, it started up and I drove it to my fathers house nearby and parked it.
I am scared to death to drive this thing. Next time I air up a tire, the tranny may go out. Or if I replace a headlight, the dashlights may turn rainbow color or something. ugh. And I dang sure aint taking it to the deer woods next month. hour from town and sketchy cell servcie....no way.
I have wife, kids, father, and employees making fun of me for driving an old Chevy. But I just can't leave the square body models just yet. Lol
HELP Please. Any ideas. Other than the local demo derby?
