The intermittent setting just runs at normal speed, same as the low speed setting. High speed works normally. But if you pull lever to spray the windshield, the wipers will only wipe as long as you hold the lever and not auto-park. Further, if you shut the wipers off from wipe mode, they just stop in the middle of the windshield.
YouTube says it's a relay:
Hopefully, that's right, because I can do that. The exact replacement costs $3.55, and the first web site I looked at says $12 for shipping. *sigh*
...which is better than $90 for a replacement turn signal switch from Rockauto. But in fact it doesn't have to be that exact part; it just needs to have the same pinout and specifications--12v DC, 20A, and so forth.
I ought to be able to find that somewhere.
Funny thing: going to Googe for this shows up hits for all kinds of Toyota models. I wonder how many different cars use this wiper switch?
Of course, it could be an issue with the wiper motor itself, which would be a lot harder to fix. I'll try the relay idea first, though, because that's a lot easier (and cheaper) and if I'm wrong, it's not such a big deal.
Got to do an oil change this Wednesday, anyway, so I can have a look at it then. At least the wipers work, even if you have to finagle them a bit to get them parked correctly.
