Question about 1999 GMC Sierra
This sounds like a weak battery. The lights, horn, etc., are all very small loads. The starter is the hardest item for your battery to push. You can take the battery to an auto parts store and they can perform a "load check". If it shows weak, then let them put the battery in for you. The reason it is harder to start in the morning is, it is the longest time since the battery has been charged, and it is usually cooler in the morning. Batteries hate the cold.
