Hi. I know this is an older thread but my neighbor has an 03 thunderbird with these exact same symptoms. No start. Blinking
headlights, slow turn signals, eratiic
power steering when it does start. The column keeps moving up and down like you are getting in and out of the car. I'm wondering if a resolution as been found for this. He already had the
instrument cluster rebuilt and that didn't fix it. It started acting up again just a few weeks later. The car is garage kept with 6k miles on it. I don't think it even has ever been rained on. It has 48 psi fuel pressure at crank and a tac signal at crank but still doesn't fire. Newer battery kept on
trickle charge when not in use. It almost seems to think it's being stolen at times. I have tried both keys. No difference. Any help with a resolution to this would be greatly appreciated. Thank you.
