Having some issues and also checking. Headlights come on but don't always come up. If I turn off engine, raise manually then restart, everything is fine and returns to normal operation. Next, during daytime, HVAC display is so dim, it cannot be read. After dark, it is legible, but dim. Clock display is normal in light and dark. Wondering if error codes might be related.

Just got an 02 Convert myself... checked the DIC codes... all of mine said "H" after the codes. Looking around online, I found somewhere that stated the "H" means "History" ... or ... it's an old issue. If it says "C", then it's "current".
I'm guessing by the Autozone-Advance Auto Parts battery that the car lost 'communication' (most of my codes were lost comm) when the battery was changed out.
Then again, if this was Rocky Horror, I'd be going up on stage to pop a balloon right now.

All of those are "history" codes and relate to bad voltage and loss of signal. Check your battery, or if it is old, REPLACE it and then clear your codes.

On the codes...I'm not sure what's going on with your headlights, they could be binding somehow or the motors are weak... ???
For your HVAC display, if you're handy with a soldering iron;
