This concorde has some weird problems. On initial start up, most every time, The trunk will open, the tach doesn`t work, the dome lights flash, the gas gauge won`t work,the 4-way and hi beam indicator flashes, some solenoid in the rear of the car is clicking (trunk?), there are prolly some more symptoms but you get the idea. This all happens at once and may go away after a few minutes. It has been to the dealer and an independant garage with no luck. Any ideas?

 

I believe that car has a body control module located in the right kick panel area. It may need replacement, or it may have some issues with its wiring/connectors or ground. It would be worth the effort to take a look at it, remove and clean the connections and ground(s) and see if that helps.

 

Any codes stored at all? That would be a great point to start might have a bus communication problem.
