Nissan Pulsar, No Gas or Temperature Gauges
Q: I have an "87 Nissan Pulsar. My gas and temperature gauge aren't
working from time to time; they decide to work but then drop off the charts
and no response.......They have a mind of their own. Can you help with
this problem. Thanks, frustrated
gas and temperature gauge on your Nissan do not use battery voltage to
operate. The gauges are powered by a voltage regulator. When the voltage
regulator is failing the gauges will operate in the manner youíre describing.
None of the other gauges or instruments will be effected by a failing
regulator. The regulator for the gas and temperature gauge is located
on the back of the instrument panel. The regulator is a snap to change,
itís just the time it takes to get to it that costs. While you have the
dash apart have the 15 or so old bulbs that light up the displays replaced.
I donít know about you but it seems every time I work in an area like
that the bulbs seem to fail a week later. either way a replacement voltage
regulator should be the fix.
