bright beam flashes

[Kim K Kaiser]

HI again,

I have the 63 cdv, with the flash assister on the dash,  

My hi lo beams flash back and forth intermittently.  sometimes they dont start flashing at all, sometimes they will just start flasihing on and off until I hit the button on the floor to get them to stop.  sometimes they sound someone is down there hitting the floor button but the lights dont respond, you can hear the click but nothing happens, as if I have no control over that floor button. I have turned off the flash assister on the dash, even put black duct tape over the glass bulb in the event it was still picking something up. I pulled up the floor, and the single wire that plugs in on the floor seemed like it was loose, like the bayonet connection was not snug, so I changed all that, got a tight connection where it doesnt bounce, tightened the whole thing to the floor, but it still goes off on its on.

I tried looking at old threads but couldnt quite find an answer.  I would like to just have it disconnected but shutting it off and blacking the gold didnt seem to help, so it must be somewhere else.  it just seems to have. mind of its own, like there is a loose wire bouncing off somewhere and making intermittent contact to cause the high beam to erratically connect.

what is the best way to go here to figure out the inconsistency.

thanks

You can disconnect the Guide Matic headlight system to stop the hi/low flashing. 

Under the dash by the steering column, you will find the guide matic relay.   The head light switch is plugged into the relay. The connector is the 3 pin connector, and it matches the 3 pins on the dimmer switch. 

Disconnect the plug from the relay and unwind it to reach the dimmer switch.  Unplug the 3 pin  connector at the dimmer switch and plug in the connector from the headlight switch.   Disconnect the single wire connector from the dimmer switch.   I would suggest putting in a new dimmer switch and saving the original dimmer switch, as they are hard to find

used.

Focus on all the headlight grounds— first  but the floor switch does seem intermittent to me

Thanks,  i ll try to clean it up first.  See how it goes , if i hv to replace, looks like a cheap part

After cleaning to shinny metal under the floor light switch if that does not fix the issue I think I would be changing the floor switch as it seems to be working intermittently 

Should be easy to find one at the local auto store  as used in many GM cars over the years

Try cleaning any grounds related to the lights 

That often is all that is needed to correct some electrical issues 

Worth a try before looking further always 

Enjoy
