I had an intermiteent turn signal, that was always solved by manipulating the switch. Some times the turn signal would not come on. some times it was delayed, and some times it would quit after working for three or four blinks. I had done some google searching and found several post on how to fix the problem. So if oyu have similar symptoms here is what I suggest before you spend ~$120 on a new switch.
Remove the three T25 screws from the bottom steering column cover. Remove both steering column covers, the lower one will need to be worked around the ignition lock after releasing the tile/ telescope lever and then slid forward. Once you have the covers out of the way use a #2 phillips screw driver to remove the two screws that hold the switch in place. At this point you should be able to slide the switch out. Once you have the switch out, take it over to a clean workbench or kitchen counter (if your significant other/ house mates will allow) and remove the #0 philips screw that holds the printed circuit board to the switch. (It was about this time I noticed a lot of thick oil all over the switch and circuit board. I assume it is the grease the lubricated the mechanical parts of the switch.) I then lifted out the slider for the turn signal part (make sure you pay attention how it goes, it will only work in one position, it is keyed but you have to look carefully). I washed the circuit board and the switch itself with some electronics cleaner (do this outside) to remove the oil from the electronic parts. Using an eraser (pink pearl) I polished the contacts on the circuit board and the spring loaded contact. Then I washed everything down with more electronics cleaner. Reassembly is opposite of assembly. All in all it took me about 30 min from start to finish and the switch works like new.
Next weekend I plan on doing the modified flush on the TF-80 SC transmission, I plan to take pictures along the way. I have seen some postings from the VIDA around the web, but no actual pictures of the process.
