Your GM dealer should be able to tell you with your VIN#.

Various problems can cause this to happen, the most common is Low Coolant level. Use a 50/50 mixture of antifreeze and water to top off the fluid level.

If that above does not remedy your situation, I would check/replace your thermostat to ensure it is in working order. A malfunctioning thermostat will either stay open or not open at all. If it sticks open, you will have a very hard time to get the engine to heat up. If it is stuck closed, you will overheat for lack of circulation of the coolant.

sounds like the transmissiion get it to a shop before you burn it up when driving

belt on the power steering pump ?? or the power steering pump itself has packed up

You will have to open the door from the inside. When you pull the handle up, there is a lever behind that pushes a rod downward to allow the door catch to release. Without this working the door will not open as if you were pulling on it without the handle lifted.

If you would like to attempt to repair it yourself, please email me first

the canister is being pressurized by the engine to operate certain controls, {ie: heater options} when the car is switched off there is no longer a need for the controls to operate but the container will still hold a certain amount of pressurized air. No the issue you have is there is a leak either in the canister or a airline going to it, My suggestion would be to raise the vehicle so you have goos access, {remember to block the wheels and use car stands} while the engine is running locate the canister and hoses in question and spray the area with a squirter in different locations, when you hear the whisteling stop, that means you have hit the leak, continue this untill it is pinpointed. Good luck.

can you write this in english please?

Check antifreeze levels immediately. You are low on coolant, and it isn't reaching the heater core.

the brush's are probly stuck open / did you look on the fire wall for a blower fan shape it's probly hiding up inside on the firewall or under a fender /if you can find the motor try giving it a good sharp rap on the end to free the brush's and hope it gets a little more life out of itself otherwise you need a new fan blower motor .

see when you say you step on it, and the vehicle stalls, it sounds as if it bein starved of fuel...you step on it, and therefore the demand is there, but not the supply. to prevent itself from over heating, the fuel pump shuts off...after a moment of cooling off, it fires right back up...get it checked at your mechanic...do the strainer on the bottom of the pump, and fuel filter as well...is it time for a tune up yet?

P0301 is a DTC code that indicates a misfire to cylinder one. It could be a bad spark plug, spark plug wire, rotor and cap, a dirty fuel injector, or the worst a bad head gasket. Cylinder 1 is the first cylinder on the drivers side, towards the front. Start with the simple and check the spark plug wire and add fuel injector cleaner to the gas tank.
