Hello, new member here.
Few days ago I got my first car ever - '03 Sunfire, previously used by my grandfather.
A year ago the service wrench light started coming up.
Up to this day, it still turns on a minute or two after the engine has been started.
Some people say it indicated that some external light is not working, but in my case they're all fine. Is there a way maybe to reset it? I know there are already some guides on the internet on how should it be reseted, but there are many different opinions (some people say that it may indicate that a BCM is damaged).
Any help appreciated.

Try this.
You need to (while car is off) pump gas 1 time & break 1 time; Then turn your key to the on (but not cranked) positions; pump the gas 3 times, press and hold the break 15 seconds; turn the car to off and then crank it and the reset is complete.

I'm curious to see if the reset procedure that carfixer007 posted works on your car.
The Service Vehicle Soon light is not related to oil changes or maintenance of any sort. It believes there is an actual problem.
Are there any other warning lights illuminated? Do all of the gauges read okay? Are there any performance issues with the car?

I got that reset from a search and now think it'* phony. What would hitting the gas and brake pedals do when the vehicle is OFF? Nothing since the network is not even on.
Oh well.

It seems that there may be something wrong with the front suspension, it sounds like something is hitting some part (?). This has already been like that for a year or two since my grandfather didn't bother fixing it.
Also the right window is completely dead and the left one (still works) may seem like the rotor is working really hard to roll it up.

I remember seeing this some time ago, tried it already and nothing happened if I recall correctly.

I could see it maybe doing something. Most GM cars over the last 30 years reset the oil-change interval by pressing the gas pedal to the floor three times with the ignition on and engine stopped, so add a hook for the brake pedal in its little mind and maybe something could happen.
