A couple weeks ago in the morning, for some unknown reason my battery was completely dead.
Today I noticed when I shut the car off, removed the key and got out I heard the heater blower still running. I turned the key back on and off and it quit. Its done it twice now and both times I have caught it. I think this is what drained the battery and I did not hear the blower running that day. It must of been on low speed.
Any ideas why the blower would stay on with the key off and removed?
