You do not say if the dash lit up, I amassuming it did.
I had this once, not in this car but the principal is the same and it was a poor battery connection, a loose terminal. Look at the battery ground to the chassis as well. Look at battery cables for corrosion inside the sheath. Is the battery flat? Do the lights work? How is the big fuse by the battery.
My entire dash lights up as normal and lights work. I will check that connection. Also as of late, my lights keep flashing when i lock my doors. Its been driving me crazy to the point that i dont even lock my doors anymore. Ive read all up on the water in the trunk post, but ive seen no signs of water. Someone else suggested my tow switch on the console. Ive notice that i absolutely CANNOT depress the tow switch on. It must be majorly seized. But the top side of the switch for OFF clicks perfect. I noticed that when im sitting in the car and i click "tow off" my dome light comes on everytime i press it. Wtf?
