Hello everyone,

I recently purchased a 2006 Ford Ranger XLT 4.0L 4x4. After a couple days of having it I noticed the dash lights, HVAC lights, and steering wheel lights went out. I checked the owners manual for fuses. I replaced 5 amp mini fuse #1 in the passenger panel (instrument panel dimmer switch). Then all my dash lights worked. They came on with my headlight switch like normal. However all my dash lights went out again on my way to work the next morning. I replaced the same amp again and they worked. But, on my way to work the next morning all of my dash lights went out once again. And haven’t worked right since. My turn signals, headlights, and dome lights all function properly. Please help, are there other fuses I need to check?

Welcome to the forum

If a fuse blows, and then the same fuse blows again there is a short in that system, and the reason fuses are used

I would use an volt/ohm meter to see if you can track it down
Pull out the fuse in question
Use a volt meter to test which terminal of the fuse has 12volts with lights on, thats the POWER side of the fuse
The LOAD side, other terminal, is the one that has the short and the one you need to test

Turn off the lights
Put OHM meter on a good ground and the LOAD terminal, should see 200+ ohms, light blubs
0 ohms is a short, or close to 0 ohms
Try turning the steering wheel and watching the ohm meter, could be a short in the clock spring wires
Move the dimmer wheel maybe it has a short

 

This was a head-scratcher for sure. I have a 4WD 2006 4.0L Ranger, and suddenly no dash lights. Dome lights, cigarette lighter, headlights, parking lights, passenger airbag indicator light all still work.

Fuse diagram has a lot of fuses marked "instrument cluster", so I tried them all with no results.

Then, in the most improbable place, there is another "instrument cluster" fuse paired with the 4WD control. This is a 10A fuse in the F10 position. I replaced this fuse and the dash lights came back on.
