Park lights and cluster won't go off after key is pulled causing my battery to die every night

Disconect the battery and ECM for FOUR DAYS then reconect the ECM and BATTERY. Let it sit for another four days without turning anything on. It should start but will run rough for about 200 miles as the ECM relearns the system. I had the same issue and that is what fixed it.

I just posted my experience in another place on this site but on my 1992 PA the accessories relay stuck closed. This relay is the one that allows you to listen to the radio etc and keep things on until you open the door then all shuts off. When it is stuck closed accessories keep running until your battery drains dead. The relay was replaced and all worked great.

Take a little WD-40 and spray beside the button with the straw. Work it back and forth the best you can to include a few smacks on the shifter itself. This will allow the lubricant to travel down the shaft of the shifter also. This should take care of it. Let me know.

It may be as simple as reprogramming your system. There is a way to re-synch your keys to the system. Use the instructions at:

That vehicle had a lot of problems with the PCM "Power Control Module" and that may be your problem.

stick the key in the ignition, turn it to the on position, remove it within 5 seconds, then hold the unlock button down and press the lock button 3 times within 10 seconds and release both buttons. The doors should lock/unlock to give you confirmation and your key should work.
