Weird Electrical Gremlin?

[1989Buickguy]

What is up with this-on my 89 LeSabre, when I turn on headlights, the instrument lights go off, speedometer stops working and the turnsignal indicators and hi-beam indicator lamps all come on!

This is pretty freaky-is it a bad switch or something?

check ground wire at the batt or ground wire under dash above left kick panal all black wires

Thanks, I'll do that.

Well, I just pulled the panel under left side of the dash and did not see any grounding wire anywhere.

Can someone please help me out here, I have no dash lights at night just the turn indicators and bright light indicator are on. Speedometer doesn't work when lights are turned on either.

what took you so long to check ground wire
check another ground wire on battary see if unpluged
but about under dash ground is there but you did not see it
check around emer brake is there

I checked the battery ground, that's ok. Guess I'll have to pull the panels and check around again. I didn't check before because it was intermittent. But now it's constant. Maybe this weekend I'll get a chance. Around the emergency brake you say?
