screen wiper question Options

[JFG]

On new years day i took my car out. There was intermittent rain for the early part of the drive. The wipers worked fine.

On the way back i had fog/mist which wet the screen but no wipers. I stopped in the services and checked the nut on the motor connection, this was tight. However there was no noise of power at the motor.

This morning i've gone out to check for faults and the wipers worked fine. No blown fuses, all electrics work fine and there were no loose wires.

Any ideas? The linkage jas been stripped and lubed previously.

JFG,
Check J-13 relay on the fuse panel under the dash. This is labeled in the prints as the fan relay, but should have been labeled a power relay. It supplies power to the top of fuse #8, I think. Fuse 8 feed the wipers, horn, fresh air blower (fan).
If everything is working well now, the next time the wipers don't work, try blowing the horn. No horn, reach under the dash and wiggle the relays and see if the symptoms change.
If you find that J-13 is in fact causing the issues of intermittent power, remove it and clean the relay prongs and with the relay turned upside down looking at the prongs, slightly spread all of the prongs very slightly. They look similar to a pie divided into 4 pieces if I remember correctly. When you put the relay back in, it may feel a little tighter and the intermittent power issue should be fixed.
