Q re earln van converted to intermittent wiper
Posted: 29 Apr 2012, 16:57
I just converted my 83 lhd with old style fuses by the Cruz/Wiki method of cutting the wires coming from the wiper switch and wiring into a relay which i have mounted on the far right of the relay block above the fuse box. Whilst mounting it at least on one occasion i ran the 53s /m wires back to front and either this or something else blew the fuse, checked all the wires and put it back, re-connected the battery and new fuse. It works like this now;- Top (2nd) setting gives fast wipers, middle (1st) setting gives nothing at all. Off setting is off as it should be. Lower setting (-1) give normal speed wiping unless but occasionally wil give a delayed wipe function. Very similar to this conversation between silverbullet and Simon Baxter
SiverBullet: I know that this is a classic fault and I should know the answer...
OK. One click down for intermittent, sometimes (very rarely) works. Usually just goes wipe#click#wipe#click at usual slow speed. I can hear the relay clicking between every wipe.
Up two positions to slow wipe, nothing.
Up again to fast and that works ok.
Switch off and it parks with the blades about 20 dgrees above horizontal. Same for wash/wipe, parks in the wron place. So...more than one fault or just a dicky front wiper relay?
Simon Baxter: Motor relies on the slow speed working for it to park.
Intermittant is also on the shunt winding.
When you're on high speed and turn it off it slows down to the shunt winding then parks.
If the motor is knacked and the low speed doesn't work then it will never work on intermittent, nor will it park.
Try a relay but suspect the motor is kerfurtled!
SilverBullet: Thanks Simon, I swapped the relay and normal wiper service is resumed
SO.......i got the relay from a scrappy and may have been a bit wet so untested etc. Any ideas? Seems like best to gte another one, anyone got a 19 relay spare?
Cheers.
