PT Cruiser 2007 wipers turn on by themselves and can’t be turned off
Bad wiper switch most likely.

The wipers might be controlled by the BCM module. If so, you may have replace it or have it repaired…
The problem might be with the Totally Integrated Power Module.

If the wipers are controlled by the left stalk (also sprayer, turn signals high/low beams, etc.) that switch may be bad. I’ve taken one apart and cleaned its contacts and it was OK. It’s not that expensive to replace it.
