Dash Warning Lights - What Are They?
« on: April 06, 2009, 04:08:17 pm »
FolksFolks
Title says it all. I suspect I have dash warning lights needing bulbs but I don't know for sure.
85 Suburban 6.2L, diagram attached.
Thanks

the Fuel one should be 4x4, can't remember the other one, but you can shine a bright flashlight in the hole and it will light up.  Some trucks didn't use both slots.

dang! I suspected I had a non-working 4x4 indicator.
I tried the flashlight trick but still can't see...anyone have any ideas?

I had the same one in my 1980 and can't remember off hand if there was anything in there. Why not pop it out? It'll take you 10 minutes.

I found this cluster pic on ebay, but, as for my 91 gmc suburban, the following is noted (a diesel will be different though)

i think the one on the fuel gauge is "seat belt" light.

MYSTERY SOLVED!

The one on the fuel gauge is the Seatbelt Warning - I forgot I had pulled the warning buzzer unit for that, hence no light.

The one on the speedo is the 4x4 indicator (did I mention its a Suburban K10?)

I ripped the instrument cluster apart (good practice, I'm sure I'll need to do it again) and checked the non-working 4x4 lamp. Bulb was OK. One terminal is live 12v but the other side gives me a click deep in the dash somewhere and a weak testlight when the 4WD is engaged...something tells me there's a bad circuit. Any ideas?

trace the wire from the 4wd switch.

trace the wire from the 4wd switch.

Say, VileZambonie, I don't have a manual or schematics for this beastie.
Where is the 4WD switch located? On the shifter or the transfer case?
