Parked vehicle. Turned off ignition. Key would not release from the ignition. Cycled the auto shift lever to make sure in park. At this point noted that I could shift out of park without my foot being on the brake. Very dangerous. I was able to remove the key by pulling the ignition fuse. I pulled the fuse and removed the key. Reinstalled the fuse. Was still able to shift out of park without my foot on the brake. I left the car sitting for a while and noted that the battery had completely drained down. I was able to jump the car off to start it. If I leave the ignition fuse in, the battery will completely drain down again.
Radiator started leaking at bottom gasket /o ring seal of tank. Also interior light goes off and on when hit bumps. Found it is tied into the ignition switch. If light comes on after hitting bump all I have to do is giggle the ignition switch to get it to go back off.
