Alright, I will tell you what is wrong, but! It will be a lot of work for you. I'm a retired automotive engineer, GM trained, for my credentials. The
problem is built in obsolescence.
Here is what happens, and how to fix it for all of you GM people. In the wiring schematic you will notice all
power wires are orange. Follow them and they all come together at a point. Here is why that is, you buy the car new, drive it for a few thousand
miles. Then one day the cigarette lighter shorts out, or the little courtesy light switch in the door frame shorts, something shorts out. This will
always happen. Then, with a power wire shorted, the rest of the power wires experience a voltage drop. The car begins to give you, the owner trouble,
and you trade in off or junk it out.
Here is how to fix this built in problem, every GM car since about 1990 has it.
Remove the dashboard. Sounds hard, but it's not on these late models. As soon as the dash is out, tie the steering column up to he door post, remove
the front seat, and peal back the carpeting from the front bulkhead back. You will see a bundle of wires wrapped in tape. Start about where the dash
edge would have been, and peal off the tape, keep pealing until you find where the orange wires all come together. The connection will have perhaps 6
wires coming from one side and 5 or so from the other side.
Go out and buy a 50 Amp, two pole automotive circuit breaker, and a bunch of ring terminals, the blue color code works fine here. Cut each wire, one
at a time, and install a ring terminal on each one. Do not mix up the two sides here! Put the wires from one side on one pole, and the wires from the
other side on the other pole, and tighten down the nuts, and wrap good with automotive tape. Reinstall the dash, make sure all interfaces are hooked
up, and everything works. Make sure you put all of the screws back in, or the dash will rattle.
You will notice quicker starts, brighter lights, quicker take off, better gas mileage.
Friend, it took me 3 weeks of solid work to find this out, and I have successfully performed this fix on 6 cars, one for me, the rest for others. All
worked fine after that, and all the cars ran like new. It is a bit of work, but if you love the car, or the wife does, she will see this as an act of
true love, and it will be worth some mileage, if you know what I mean.
