Question about Cars & Trucks

1 Answer

2000 Buick Regal... All the lights, every single 1, in the dashboard started flashing & the car went dead. Will not start back up unless the head lights or emergency flashers are on but will die again if turn signals are used. What could possibly be the problem, is there a computer reset button or anything?

I had this same problem a couple of years ago, $2000 dollars later my ex in-law spend at the dealer and the problem still existed, (they replaced the ignition switch, the entire fuse block assembly, battery, alternator and a couple of other things ). I bought a new turn signal switch for under $100 and never had the problem since...

Most likely it is the ignition switch (the key ignition switch) in the steering column ($100 at a dealer).

It may be a loose negative battery ground cable, too.
Check the negative battery cable where it conencts to the engine ground. It may be loose, corroded, damaged, or otherwise not making a good ground contact.

Add a grounding strap ($11 - AutoZone) from the engine to the chassis. That may help, but it's most likely the ignition switch.

SOURCE: 1991 Ford E150 turn signals do not work,emergancy flashers flash constantlly unless the flasher relay is unplugged from fuse block

Hi,

If I understand you right based on your post/description, the signal lights would still turn on even if any or both of the flasher relays are removed. Should this be the case, then the signal lights are not getting the power from the flasher relays but from the brake light circuit.

Perhaps your concern is not with any of the flasher, but simply missing or loose ground more particularly with the rear lights. Perhaps you could try determining which of the wires for the brake lights and signal lights (as they come out of the light assembly) would be ground . A test and even possibly a temporary workaround is to hard wire a second ground connection from the determined ground wire of the lights and attach it to any conveniently located bolt or screw to the body. it may be to your advantage to do this on all the rear lights assembly.

Hope this be of initial help/idea. Pls post back how things turned up or should you need additional information.

Good luck and kind regards. Thank you for using FixYa.

If you turn your key forward (And make sure the fuel pump kicks on) Cross the starter terminals with a screwdriver. If the car starts like this you have a bad ignition. You can replace the cylinder or the whole column.

Buick Regal 2001 LS dashboard lights flash off and on


It turned out the ground wire to the battery was loose, Evidently, it loosened up when driving so mimiced the earlier symptoms because it connection was sporadic. I hooked up to a computer to verify after connection tightened and it came away with no errors or problems.
