moved to NYC a month ago, came home, and started to drive my car. When I was driving i noticed the heat wasn't working so I hit the reset button and it started to work. I thought everything was fine, but when I turned to **** to make it go off it didn't (it works on all settings and changes strength).

Now, when I got home and turned off the car completely it keeps running and won't turn off at all. I have let the car sit for 20 minutes and it is still running. any ideas on why this is happening and how to stop it?
