Wipers locking doors?? Dafaq?

[AWSneer]

So... I have this odd problem that I noticed randomly one day, sometimes (only sometimes) when my windshield wipers hit full stroke at any speed, they will lock my doors...

What?

Let me say that again:
Sometimes while driving in the rain with my windshield wipers activated (at any speed), at full stroke, they activate my door locks. Every wiper stroke would activate the lock (whether it was locked or not).

I'm sure I can duplicate it but I'm wondering if anyone ever saw this before? Does it have anything to do with the replacement of my steering lock?

Any incite would help!

Thanks,
Andrew
