Looking for help on a problem with my T100 Truck. All the Dash lights went out at the same time. I have checked all the fuses but does not seem to be a fuse problem. Does anyone have a Electrical diagram that would help trouble shoot this problem.

Thanks

The same thing happened to a friend of mine. He spent hours checking fuses and wires only to find out that it was a bad dimmer switch

Thanks for the Help. Came to find out the tail lights and dash lights was on the same fuse. The fuse was blown.

Thanks

mine are out too and i dont have the fuse panel cover with the diagram on it... none of the fuses are blown... i havent checked them with a test light but they appear to be fine...

can anybody tell me where the instrument lights fuse is located?

also, if the dimmer switch is bad, wouldnt the lights still be illuminated a little bit or do they go out completely?


thanks in advance... :smile:

I resolved the mystery of why the instrument light was out on my new 96 T100. I removed the 4 ( 10mm ) bolts that secured the lower finish panel no. 1 and discovered that the plug to the dimmer was disconnected. Plugged it in and tested. No more excuses for speeding in my T at night.

I am having the same problem. It there any way to check the dimmer switch? I was wondering if I my ac cluster is suppose to light up as well?

You could pull the plug to the dimmer and ohm out the dimmer with a multimeter. Best thing to do is to check yer fuses and then check to see if the dimmer is still plugged in. ;)

AC cluster? You mean the button? Or the control panel? The heat/ventilation controls has a small bulb behind the panel. This (http://www.toyotanation.com/forum/showthread.php?t=321624) is what I did to replace that bulb. :D
