PT Electrical Problems

[DDPTman]

I have a 2003 PT - got a head scratcher for you...... my car has several issues - most likely all related......... when the car is running, the door light indicator is on and the dome light comes on and the door chime is going on and off.........but all doors are closed tightly.... when I stop and shut the car off, the door light indicator stays on as well as the dome light - never shuts off....... I actually have been having to shut the light switch all the way off to keep the dome light from running the battery down at night.......... To further complicate things, when I turn my my fan - then my dome light also comes on - so when I am driving, I can either have my fan on - or I need to turn off the light switch to the interior lights - which means I have no dash lights at night....
Any idea's on where to start ? I want a rough idea before I take it in to the dealership ..... thanks !

Check out the door light on/off switch for each door.

If a switch has failed in the shorted mode--the interior light/door chime will be constantly activated unless you have them off at the dash.

Does your vehilce have the message system that reports door ajar? If yes--does it show a door ajar?

Tail gate switch--same questions.

If one of the switches has been pushed out of the door jam and fallen into the body cavity you will have the same ligh/chime issue.

The fan and light issue is a new one for me.

Have any electrical mods/repairs been made/attempted just prior to this issue arising?
