Is the neutral safety switch ok ?
Does it have an anti-theft system ?

Check your brake fluid level . if it is not low get your vehicle to the shop. Brakes are not something to just hope will work when you go for them. It's not safe for you or anyone else walking or driving !!!!

Interesting same thing here, radio and a/c controls, the cabinet ambiant and the pocket lights on the doors but not the cabin, or dash, or information panel. Have you gotten yours fixed yet, I have check the connectors, pulled the fuse, nothinig found an odd thing drove it through dusk when the auto lights came on and wala there it was for 4 days and gone again.

I would have battery checked/charged and/or replaced. Then starter, then alternator checked.

at the minimum, since you mentioned all the idiot lights coming on, your alternator is fried. have someone put in a new alternator. if it's still acting up, have someone go over the computer.

check your injectors too. maybe the problem lies there

sounds like a bad battery or bad battery conection

try transmission fluid? (Smile)

Have the battery checked.  You may have heard a fast clicking sound when the lights were flickering, if so it's coming from the starter solenoid.  If the battery is bad, have the voltage regulator and alternator checked also.  A bad voltage regulator or alternator will kill the new battery.    

Try starting with jumper cables, if that works, you can pull the battery out, take it to a auto parts store that will test it for free (most parts stores will do this).  If it's bad, you can put a new battery in and then drive straight to somewhere to have the charging system tested.
