ok the reverse lights will most probably be the switch on the gearbox...either the wires have come off the switch or the switch is broken, always best to just replace. Most of the rear lights are probably just an earth problem. With the battery not holding charge obviously something is draining it and or the voltage reg probably not working properly but just test with a multimeter and you will find the problem. Probably best to check all the fuses properly by removing and cleaning the terminals, clean all terminals with crc or wd40 on the contacts(an old electricians trick which i got taught). and the display not working best to check the dash....not hard at all to just take the facia out by itself and just test from there. With the window winder take the trim off and have a look at the mechanism if its stuck just take it off and get one from someone, im sure someone will have one. Wiper blades you can pretty much get anywhere. Noise from the rear wheels could be anything best to jack it up and check the brakes and the wheel bearings. Drivers door its best to check the alignment and see if you can get it to shut properly otherwise just get another door lock. With the radiator under the cap is where it is meant ot go to an overflow take either fit one or solder it shut but best to get an overflow tank as they can come in useful. With the head lamp check the connections as one or to may no longer be attached to the light properly anymore or there is some corrosion in the plug, just unplug and see the spray crc or wd40 into the plug and retest again. I hope that helps
