Nickos It takes about five minutes to take your headlights out. Take the bulbs and parkers out and inspect your reflectors if they are dull hazy replace. Connect your bulbs up and remember your ignition coil mus be on for the headlights to work. Check brightness without them inserted in your lenses. Buy some new ones and check brightness (always handy to have spares) If obviously brighter then through your old ones away. Don't touch the bulbs with your fingers (ever even if off). If They are the same in brightness in or out Jerry Rig some leads off your battery and test the bulbs there if brightness is increased replace wirng to globes. Just testing the wiring gives out twelve volts doesn't tell you about the resistance of the circuit and under load old wiring gets hotter and resistance increases. Therefore you will need to do the long way round. Next The Door This will take a while Take interior lining off sliding door. Photograph the positioning of cables as there are different flavours. Remove rear locking mechanism. Pull apart soak in petrol clean and lubricate. Do the same for the front except with mine you couldn't pull apart so clean and lubricate best you can Reassemble Next remove left rear window cover housing of rear roller mechanism repair clean and lubricate (Roy has replacement rollers and bushes) reassemble. Next Replace Rubber Seal around door (Roy) Adjust ment Close the door completely and see how she hangs. If its low the bottom bracket needs more shims. I cut mine from an original. If its hanging Ok then check striker mechanisms. Start at the front. The striker plate can be adjusted three or four millimeters up down in out and has shims align be carefully and slowly closing the door. Half tighten them and close door and they will "move to a good position. If there is not enough adjustment then the tongue mechanism can be adjusted up down. When you have the height of the door (lower roller) The front latch aligned. Then go to the rear of the door and repeat process. The striker plate has some adjustment and the latch has some adjustment. Slow careful alignment and adjustment will end you up with a door that closes with such precision you will have the whole neighbourhood come out and you can demonstrate it to them and they will admire it and want a go. This is the complete way if your rubbers and rollers and mechanism are all ok then just height, front then rear adjustment. My rear mechanism was just a little sticky and that was the problem with my sliding door having all the problems.
