Code is specific to your vehicle .. Dealers are not supposed to charge for unlocking and they should have given you the code to write down in your owners manual.

You most likely need a new window motor. you can check on the price of them at your local auto parts store, but usually the hardest part of changing it is getting the inner door panel off and back on in one piece. Usually the drivers door window motor fails first, as it is used the most.

I had one replaced on my wife's Suburban last month... with parts and labor, you're looking at about $400 for one side. I'm in central TX but shouldn't be that much difference

the fan on the newer GM trucks are threaded on to the water pump with a large nut .it unthreads counter clockwise as viewed from the front looking rearward. you need to hold the pump pulley and loosen the nut. once it breaks loose you should be able to unthread it by hand.
good luck chris

Just because your accs. function does not mean the battery is ok The first thing to check is the battery, there could be dead cells in the battery your starter need maximum voltage if a cell is dead the battery generally will not turn the engine over check that battery

check your exhaust valv and as for not being able to connect to OBD system, check all of your fuses.

Easy fixes

1- get a can of mass air flow sensor cleaning solution and spray it on the sensor. The sensor is in line right after the air filter. It is in the tube that is directly connected to the box the air filter is in. You can see a wire connector going to it. Easy to open up, look inside and you will see some thin wires going across with a few nodes on them. Spray these clean. re-assemble.

2- get some fuel injector cleaner and remove the tube where it goes onto the manifold.Same tube air sensor is in, except at other end. Spray some cleaner in and run the engine. I am not a pro and I get scared there will be a fire so I reassemble the entire tube after spraying and before turning on the engine. I repeat it a few times.

#1 helps the most and you will be sooooo surprised how inexpensively you solved a seemingly major engine problem. I had the same thing when turning in a parking lot, slow turning. Problem gone in 10 minutes work!!!

ither you have a loose connection to the sending unit, or you guage is faulty. i would check the wires and connection. considering the age of your vehicle, I doubt you have a faulty gauge. even though this rarely occurs it's possible that you have a stuck float on your pump inside the tank but it's possible. please rate this .........thanks
