On my 2001 Dodge 1500 van when I shut the ignition off it doesn't shut down the power to the heater fan if you turn the tumbler very very slightly counter clockwise it shuts the power of to it. I just replaced the tumbler in it because it went bad but it was doing this before I out the new one in. My question is , is there an adjustment somewhere that might correct this the park indicator won't always light up either I don't know if the two issues are related or not .

 

Bad ignition switch perhaps?

 

I only wish it was that simple. Those parts were just replaced.Thanks anyway
