It's a safety feature. For example, if there is no oil pressure when you start the engine, you could not see that unless you were in the car and could spin a bearing or seize the engine by starting it remotely and letting it run unattended. So when the check engine light is on, there is something not working properly with the engine/engine management system and it wants you in the car where you can see the guages and turn the engine off immediately if there's a serious problem.

It does sound as if something is drawing the battery down. First thing you need to do is to check the battery...have it fully charged and load tested. Once it's been established that the battery is good, disconnect one cable from the battery and put an ammeter between the cable and battery post. Any draw will show on the meter. At that point, begin removing fuses one by one till the draw stops. that is the system with the problem...then you need to check each component served by that fuse (wiring and relays as well) Your radio will draw a small amount to keep the clock running and some alternators will have a slight draw as well but those should not be excessive.
Ice on the inside of the windshield is often caused by a blocked a/c drain causing the inside of the heater box to have water inside...with the heat on, the water evaporates just enough to condense and freeze on the glass under certain temp conditions. If you have water in the cooling system, (not antifreeze) that can also happen if the core is leaking, but I doubt if that is the case as you'd have larger problems by now than just a bit of ice on the windshield. Under certain normal humidity conditions it can also happen in a normal system so if it only happens once in a while, don't worry about that.

When was the alternator replaced? was it a remanufactured alternator? This is common on GM trucks, fluctuating voltage is caused by a faulty alternator voltage regulator. Have the alternator tested, strong possiblityits defective!!Hopefully this helps!!
