Hi

I have a 1987 Nissan Sentra, gas, carb, 4 door.

The fuel gauge and temp gauge just stopped working.

The two things that they have in common is a voltage regulator for the
Combination Meter that is what Nissan calls the instrument panel in the
service manual.

This voltage regulator only connects to the fuel gauge and water temp gauge.
Both just died on me.

First where exactly is it located? Then how hard is it to replace? Does
the entire dash need to be pulled?

Thanks

Sounds like the likely culprit.

Usually is on the back of the instrument cluster or inside it. On some cars
the regulator is Incorporated into one of the gauges yet both share it's
function. Usually it will be the more expensive of the two if that's the
case, I know Honda does it that way..

The instrument cluster has to be removed from the dash but not "the entire
dash"..

Also look out for cracked tracks on the instrument PCB. Vibration causes
these cracks. I had one on a Sunny once when the rev counter stopped
working. A blob of solder to bridge the crack fixed it.

This is especially true at the points where connector pins are soldered to
the board.
