Anyone know what the resistance of the dimmer pot should be? How many
watts? I need to replace it or maybe just put in a fixed resistor at
about half brightness setting

Thanks

Dont do fixed resistor, too bright distractions will cause a mortal
accident, death.

So measure your old POT, with multimeter.

It's not a pot, it's a rheostat. If you plan to replace it with a
resister, it will need to be a high wattage wirewound one. Could get
really hot and start a fire. Better off to just replace the dimmer.

OK thanks  I think I will get a new dimmer.
I can reach under the dash and pull the 2 wires going to the dimmer
and make it work for a while so I thought I could just cut them 2 and
connect them together or put in a dropping or current limiting
resister. Why would I think along these lines? Because it seems to be
hard to get the dimmer switch out, but I bet I'm wrong there too.
Anyone tell me how to make it easy ?
TIA

Get one from a junkyard.  Most Late model Nissans use a small DC
amplifier for the dimmer.  It runs at ~3-7 watts, so any rheostat would
get pretty hot and probably cost more too.
