Electrical insanity in a 1995 concorde

[Joust]

Hi,
lately my concorde is acting up.
sometimes the environmental controls would not turn on when i start the car.
No Blower fan, no electric windows, ABS and airbag light on.
if i turn the key off and restart the car it would be ok.
this past weekend, it apparently did not turn off and killed the battery.
yesterday I had to turn the key several times to get it to turn off properly. this morning, it would not turn on at all.
is this common problem? I have another ENV control panel module I'll try tonight. but it sounds more like ignition switch issues to me.
I changed the switch a couple years ago for an unrelated problem.
any ideas/thoughts ?

I totally fixed it.
it was the ignition switch.

I opened the switch to see why. One of the contacts was burnt a bit and it had overheated and melted the cams on the main barrel that the keyswitch turns.
I had the old one that I replaced a couple years ago. I cleaned up the contacts in it and its perfect. it is a PITA to get appart and back together properly but worth the time i think

Perfect timing Joust Same year and similar issue. The system has been going on and off on me for a few months actually. It defaults to a defrost mode that gets you around in the winter but roasts the crap out of you in the summer. I figured it was rotten wiring somewhere.
How do you get the ignition switch out?

Found another post with directions on accessing the ignition tumbler assembly.

Your ATC (Automatic Temperature Control) Head Unit is going bad, that is a classic sign when the display blanks and the defrosters come on with the fan at a moderate speed and blowing full heat.

Try and find one online or at a wrecking yard that doesn't think it's made of gold, that unit can be expensive.
