Hey!
I have a strange electrical issue in our 1998 Sienna, and I was wondering if someone out there has some insight on how best to investigate this.
Earlier this year the windshield wipers started doing the wrong actions when the control arm is in each position. The fluid and rear wiper controls still work normally, but for the front wipers what should be:
1 - off
2 - intermittent
3 - continuous
4 - fast
is now:
1 - off (stops wipers in current position)
2 - continuous
3 - continuous
4 - off (stops wipers in current position)
And as an added bonus, a change in vehicle angle sometimes stops wipers in mid-sweep for a minute or so.
My first thought was to replace the control arm in the steering column. I did so, but the replacement gives exactly the same behavior. I’m not sure what else to check, but I would welcome any suggestions. I hope it’s something I can simply replace, but I’m out of my element on this.
And FWIW, I have a multimeter but have little understanding how to use it properly (although I can handle most mechanical issues, I bow to those with an understanding of the subtleties of finding electrical issues).
Any thoughts on this?
Thanks!
