Ok so I had the symptoms of a dirty throttle body and i took everything off and it was def dirty, cleaned it all up and installed it i had the battery unhooked the whole time, it started with another issue tonight, i started it up earlier today and the heater was on, the interior lights started flashing, dash lights guage lights and the heater shut right off, flickering and blinking, does it when i engage awd too.
i just spent 700 buck the other day on a new alt new belt and new tensioner, the reason that i did the throttle body was because when i had the heater on last week, and the rpms would drop below 400 then back up to normal then a few seconds later did the same thing soon as i shut the heater off and problem solved...
This truck is beginning too be too much, this is my 3rd chev truck all under 200,0000 kms and they were all garbage this one seems to be going down the same road...would love to put 500 kms with out something going wrong with it...
Any input would be great
Thank you
Tom

I'm willing to bet when you reattached the battery cable, it wasn't seated 100% and it's wiggled loose causing your issues. I had the same thing happen when I used an extended battery bolt (it was too long and wouldn't screw in completely)

Bottom of the central dash radio stack, passenger side. With the trim panel (Envoy is different than TB, perhaps) removed.

You may have a flaky ignition switch also, or perhaps one of your battery cables isn't fastened well.

So pull out your meter and see what you're getting right now at the battery and the front fuse block terminals. Inspect the ground wiring to the fender as well.

Thanks for all the help guys i just ended up taking it to the shop, i like working on my own stuff but i dont have a garage and working outside here in the winter can be a pain at the best of times appreciate all the help and will keep posted on what the problem or problems ended up being

Thanks for the report, and sorry you had to take it somewhere. Any chance you can ask him if it was the ground splice pack I suspected? There really isn't another major ground in there that I recall. And almost nothing else can cause the collection of symptoms you had.

I think that was the culprit, i believe he mentioned the splice pack, i usually like doing my own work but at that point i was getting much to frustrated to do anymore myself. and shortly after i got it back i had a fire due to my transmission line blowing off and spewing trans fluid all over my exhaust, ended up having to get a new trans put in....soo from the date of my last post im out almost $3000 buck on it...still looks good though, could be worse cold have a ford badge on the front
