There are fine files made for filing points, but a piece of fine sandpaper folded so that the grit is on both side works just as well. Shut the power off before doing either.
Either switch brands or clean them with eyedrops
That is doubtful. The contacts are probably burned/damaged.
dirty contacts on switch. You can replace the whole switch with expense or have someone who's technically inclined pull the switch apart and clean the contacts to bare metal.
take apart and clean copper contacts, no need to replace.
Try a new switch or just clean the contacts on it
you need a new headlamp switch, power for the lamp motors comes from the switch, if you are very carefull you can take apart the switch(you will probably see carbon built up on the contacts), clean the contacts off and give them a slight bend,apply a small amount off lithium greese. you should be good to go.
yes, you can. If you wash your contacts with tapwater, you can get an infection in your eye. Always make sure you keep your contacts clean and clean it with the solution your optician gives you and youll be fine! (:
1) Replace flasher unit OR 2) Clean turn signal contacts with WD40 Had same problem. No turn signals but hazards work. Online research suggested most probably flasher needs replaced or bad contacts in turn signal switch. Mine started working out of the blue - I think contacts were a little gunky. Someone with similar problems suggested blasting the inside of the turn signal switch with WD40 to clean any gunk and corrosion from the contacts.
sounds like you have a short in the wiring to your fuel pump! clean all contacts and check for proper grounds...
Get John Muirs -"How to keep your Volkswagen alive, A manual for the Compleat Idiot" and Bentleys "workshop manual". They have a huge amount of info, John Muir is a "real world" work-book and the Bently Manual is the VW "Official Workshop Manual" . Your gonna need a helper. Check the bulbs, check for power at the contacts for the bulb. Make sure the key is on when you are checking for power. If you have power at the contacts then clean the contacts up good including the contacts on the bulb. Check and clean up the ground wires also. You might want to unscrew then screw the the Tail Light mounts to make sure the ground is good. If no power at the contacts then check the fuse. if the fuse is OK then check for power after the fuse. Clean the contacts up on the fuse holder. If power there then check for power at the brake lite switch at the master cylinder. Take the plug off and check for power going to the wire. If power is there then the switch may be bad. Make sure the contacts are clean.
If your battery is fully charged and the connections are clean and tight, the problem is probably that the contacts in the switch are corroded or worn, meaning your ignition switch will have to be replaced.
Open the fob. Remove the battery Use a pencil eraser to clean the battery contacts Use pencil eraser to clean the switch contacts on the printed circuit board (they look like interleaved fingers typically) replace the battery with a fresh one. If that doesn't work, buy a new FOB.
