Default Temp & Fuel Gauge Inoperative

2002 Tacoma - temp & fuel gauge needles are bottomed out. Speedo & tach both
working, and so is the illumination in the instrument panel. Anyone know the
common denominator for the two gauges? Fuse tested OK, but I tried a new one
anyway.

The most likely common denominator for the temp and fuel gauges is a common
ground. Does the truck have any aftermarket or dealer installed accessories
like a remote start, audio system, GPS, etc.?

It's a 2002 Tacoma. Check for rust...

No aftermarket anything, Ray. Only two things have happened to the truck in
recent weeks: I changed the light bulbs for the ash tray and glove box.
While doing this, I discovered that Toyota is using former "engineers" from
General Motors, because there was barely enough slack to allow me to handle
the bulb socket correctly. It required a bit of tugging. I wonder if
something was dislodged.

I also installed the rubber winter footmats. Uh oh. Another footmat
disaster....

Toyota used a fair number of GM suppliers for vehicles assembled at the
NUMMI plant.

I don't think that changing bulbs or tugging on a bulb socket for the ash
tray or glove box would cause the problem,

Unscrew the screws on the underside of the bezel surrounding the instrument
cluster and tilt the cluster forward to see if you can see any loose wires.

Bad ground. OR, you're out of gas and the motor is cold.

I noticed that you told Ray that you had to tug on some wires to get the
light sockets to come out far enough to change the lamps. I'm gonna second
Ray's suggestion to pull the instrument cluster out and see if you unplugged
something. You probably unplugged something while yanking the wires around.
I don't recall the layout of the guages in my daughter's Tacoma, but if they
are adjacent to one another, I'd expect you to have pulled the connector
off.

They use a lot of ribbon cables that are easy to unplug. They might be
easier to unplug than to plug in again. You should be prepared to not find
wires, per se, connecting the guages.

From left to right, the arrangement is temp gauge, tach, speedo, fuel gauge.
But it's probably still just one bundle for the two that are having a
problem.
