I drove the car to the battery seller and showed them the test from the dealer. They ran some sort of battery test five times. The first four times it passed but it failed the fifth time. With that they replaced the battery for free.. So once again my problems have disappeared.
Turns out it was all due to a bad window control switch. I don't know where it is located but it cost me over $400 to get the dealer to replace the switch. Since then I have not had any problems.
The hot radio panel was discussed lots of times early on and I expect it's just normal. The heatsink for the output driver transistors may be close to the front, I don't know for sure but it's a possibility.
The A/C has always been quirky on my 02, it has to do with the cooling fan design. It's a long technical explanantion. If the A/C is not working at all that's another story.
The most common reason for a CEL to come on is the fuel cap being loose, crooked, or the seal on the cap being worn or cracked. I found the latter to be the problem on mine. The seal isn't just an O ring but a special grooved extrusion (kind of like an O ring with a lip) that gets small cracks over time. I was able to just turn it over and get another year or so out of it before I replaced the entire cap (couldn't just get the seal). Keep in mind that the CEL won't go off right away on it's own even if the problem is cleared. It will take several start cycles. It can be reset through the OBD connection however.
I've had the airbag light stay on after starting a couple of times in 8 years, but shutting it off and re-starting has always taken care of it.
I don't remember 6 recalls. I remember the wiper motor, tail light bulb socket assembly, and the trans lockout button (which I opted not to do). There was also a few TSB's that were done during service but those aren't "recalls".
Good luck finding your solutions.

I have a 2005 Trailblazer problem. The tailgate will not unlock, the rear wiper is not working, and the keyless entry is not working all at the same time. The problem was intermittent and then finally didn't work. I took it to the dealer and they said it was a frayed wire and they repaired. Now the problem is back and is intermittent again. Any ideas where I could start looking?
Thanks.
What is causing my wiring to get so hot? Any suggestions?
This is how we fixed it. As you know, you have to think outside the box. My husband started thinking about how the car is run by a master computer. Computers take time to shut off, slow down... you have to be gentle w/thm. So, when stopping our car, we turn the key slowly to the first shut off- at this pnt the engine is not running but all lights and radio are on. Then we count to 9 or 10 and then turn the ignition key again. Now we have turned everything off but the radio would still be running. We would wait til the car shut off everything itself- and NO one opens any doors until all turns off. Then the 1st door opened is driver door- keep open until all other doors are opened & closed. I swear it works! It took car about 2 months to reset itself, now when we go through process radio turns off immediately when you turn key in ignition to final off position. The car hasn't been dead for the last 2 months. You must follow routine. We do still go out at night once & awhile and make sure we don't hear anything draining the engine.... good luck......
