Wiper Woes in RHD Country

[240 in OZ]

Hello All

I just finished installing replacement/believed correct wiper/headlight and turnsignal swithes on my 09/71 240-Z and have only one speed of wipers working, the low speed. All else seems fine except for the high wiper speed. Note the switch installed is one without the intermittent wiper setting (my wiper motor only has five wires to it).

The switches which I have now removed were a matched pair from a 260-Z (intermittent wiper function and pass button at end of indicator stalk). They had been installed with the use of what I will call an "adaptor harness" rather than hacking up the original wiring harness of the car (thanks someone). I did not install these and they were there on the car when I purchased it. The intermittent setting never worked nor did the pass button but I did have two speeds of wipers with these now removed switches.

I believe that all of the wiring on the harness is correct and hasnt been modified as all of the connections were used. There is one wire which isnt used and that is a thin wire on the turn signal three pronged small plug; the harness connector for this has three wires while the corresponding switch connector only has two wires. The turn signal switch has the separate green wire with the spade bit for the power. The turn signals seems to work OK, although a little '****y'. I assume this may be worn contacts in the switch (is this able to be repaired??).

I initially thought the same for the wipers, but this didnt make sense as the low speed works fine and I would assume that this setting would be used more frequently than the high setting...hmmm, we are talking 240-Z wipers! Lights are fine both low and high beam. I am in Australia and dont know if there was any difference in this specific wiring between the LHD and RHD models.

If anyone is able to offer any help in maybe tracing the wiring from the wiper motor through to the switch or offer any ideas of what to check for it would be appreciated.

Thanks, and regards
