Sounds like two separate problems. For the headlight, check the headlight relay in the underhood fuse box (may be more than one if you have DRL), but may also be the headlight switch. For the dash lights, there may be a dead spot on the brightness control. Rotate it a few time to see if that fixes the problem.

Yes - you can try pulling the switch module and checking the connections or power as you try each switch.

it is a safety requirement that the cap has to pushed down to allow it to turn
have you tried that process

First why are you adding it are you overheating? Just a question here for a regular coolant change after you add it you must run the engine to circulate it but when drain it if you didn't drain the engine also there's still fluid in there and that's why only a little bit did you remove the coolant bottle cap when draining it ? Also you obviously had the car jacked up so this raises the engine on an angle keeping a lot of fluid in and you need to remove the lower hose for it to come out on level ground

Engine misfire can be caused by a lot of things, such as lack of spark, low compression, poor fuel quality, metering, unmetered air entering the engine, etc., which leads to lack of combustion. When this happens, the computer triggers the Check Engine light and shows a code such as P0305.

I would start with the plugs and wires, then the coil. If it persists, further expert analysis would seem to be needed.

The ECM in those years had removable Proms and did not need flashing as new ones do . Some relearning is performed as the vehicle is driven . What quirks are you having ?

Any DTC'S - diagnostic trouble codes stored in any module ? PCM/ECM , BCM , TCM etc..... That would be the first diagnostic step - hook up a factory or some other type of professional scan tool . We don't guess , we test . Then we read service information on how it works . Or suppose to work . Backup Lamps The CHMSL/BKUP fuse in the instrument panel (I/P) fuse block supplies battery positive voltage to the body control module (BCM). When the driver places the gear selector in to the REVERSE position, the powertrain control module (PCM) sends a class 2 message to the BCM. The BCM then applies battery positive voltage to the backup lamp supply voltage circuit. The left backup lamp is grounded at G301 and the right backup lamp is grounded at G302.
DTC B2545 Backup Lamps Circuit
DTC B2545 is set either when the backup lamps supply voltage circuit is shorted to ground or opened, or if the CHMSL/Bkup fused voltage supply circuit to the BCM is shorted to ground or opened.
If no DTC'S are set ,then go to diagnostic flow chart . Backup Lamps Always On

You can remove the back seat, and it should give you enough room to pull the inner door panel off..

Check wiring. The main battery cable at starter as well as the line going to the battery fuse box at starter is likely lose or has defective terminal end.

Is the heater / A/C system manual or automatic ? It doesn't really matter , both systems have a blower motor control module , not a resistor .

Your best bet , take it to a qualified repair shop .
