When the horn is pushed, the rear wiper comes on (intermittent setting).
When I flash the brights, the rear wiper comes on (intermittent setting).
When I push the hazards, the rear wiper comes on (stays on as long as the hazards are on).
If I turn the brights on, nothing with the rear wiper. Only when I "flash".

I just replaced the rear wiper switch and the multi-function switch (turn signal module).
Disconnected the battery for more than 10 minutes.

Still does all of it.

Help!

check battery to body ground and engine to body ground . also check for a melted connector at top of latch as it's the ground wire it may be the problem if it is put aheavier gauge ground wire in like 12 gauge to module in gate. if it continues have it scanned for codes by a local pro
