Code 300 means you have a random miss that is not serious enough to pick one cylinder. The computer measures RPM on each cylinder as the plug fires. So it is not that a cylinder is not firing but rather that it is not producing enough power.
Other causes are vac leaks and lack of fuel.

Have you tried to add any refrigerant to it lately? The pressure can go up as it heats up, to the point where the pressure switch cuts the compressor off.

this is a small leak in the evaporative emission control system.Most common cause is a loose or faulty gas cap but not always, Sometimes the check valve in the gas cap doesn't seat properly allowing the gas tank pressure to bleed down. The EVAP system needs to see a positive pressure in the tank.

The 2004 Trailblazer has two fuse panels, one in the under hood and one under the middle row seats. The radio fuse is marked RADIO fuse # 41 and is a 15 amp fuse located in the rear fuse panel. To access the rear fuse panel flip the seat behind the driver to the upright position, under it you can see the fuse panel and a diagram should be on the under side of the cover. 

Good luck and hope this helps.

I disconnected the battery, removed fuses 10 and 28 adjacent the battery and waited twenty minutes. I then hooked the battery back up reinstalled the fuses and started the vehicle. The battery light went out and the battery not charging message did not come back on. I then went for a test drive. I had a celebratory adult beverage because it worked.

Torque should be about 30-40 ft lbs. This is essentially tight by hand, no torque wrench is often used. See this how to video: Sorry the video wouldn't upload. But the shop (A1 Auto) tightened by hand and for me that's 30-40 ft lbs with open end wrenches.
