Fuse, horn pad, horn relay, or horn itself..

I am wondering if you have checked and reset the steering geometry? After all that work the front wheel toe could be miles away from the ideal setting. Mostly checking and adjusting the toe of the front wheels is beyond the scope of the home mechanic so after the sort of work you have done the first journey needs to be to the nearest trustworthy vehicle workshop offering the service. Considering the list of work you have done it would be advisable to request a full alignment check rather than the basic toe check/reset. The toe setting is not just important for predictable steering but also to prevent excessive and uneven tyre wear and reduce road noise and fuel consumption. When the toe setting is incorrect the tyres are effectively being pushed or dragged sideways and a tyre can be lost in a very short time. An unwise mixture of tyre brands can produce similar symptoms. I call it a random lane change facility and perfectly legal and well-maintained cars can suffer from it to a potentially lethal degree by allowing tyre sales people sell the tyres they are making the most profit on that week instead of the ones matching the other tyres on the car.

This could be a number of things, The first thing I would do is depending where you are located, take the vehicle to an auto parts store that provides *FREE* code reader services (ie.- Advance Auto, AutoZone, NAPA, etc.) and have your vehicle scanned for error codes. Using these codes you could maybe find your problem. If that is no help check to make sure all your electrical connections are good, There may be a loss of communication with the brake module. Finally have the error message *Reset* to see if it happens again, and if it does' you would probably need to have it checked out by a Chevrolet repair technician! Hope this helps!

find blower motor over by glove box area and hit it if it starts workin you need new motor

check coolant level and look for a leak

You need to check fluids or take to service at Chevy.

You need to have your ECU read, you can buy a ODB reader online for around 10bucks. Work with Bluetooth in sync with your phone. This way you can read error codes the ODB reader lists, look them up on the net and then take it from there. For me, i helped alot when i had issues with my engine management light going on after i replaces parts on the block. I need to check whether your car is using ODB or ODB2 port for the reader. Being i 2002 model im guess ODB, but have a look online. Do alot of work on cars, except i dont have much experience with automatic transmission car's as we don't drive them much in Europe, we want pure performance :)

Disconnect battery for more than 5 minutes, and upon connecting plus pole again, car should release e-brake.

There is a purge system on the gas tank that removes vapor from it for emissions purposes. When there is a problem with this system you get the error code. This particular error means that it is a large leak in the system. It could be a bad gas cap, defective connection for the hoses to the gas tank, there is a canister that absorbs the vapor and it could be bad or damaged.
