What timing, just had these same symptoms start happening 2 days ago.

I pulled the light switch and the dimmer hoping to figure out why it wasn't working.
I have a wiring schematic in my Haynes manual but it is somewhat unclear on the wiring to the dimmer.
Any chance anyone has a better wiring diagram for a '95 854T?

There was a recall on some 850 light switches.

There are two tabs and slots on the side of the switch that hold it together, The plastic near the slots breaks away. the switch may feel a little funny

You can fix it with a little tape.

I agree with Klaus, the little rheostat might be messed up
you might try a little TV tuner cleaner on it, see if it starts behaving.

Here's another hint, once you get the lights working, set the lamp level on the low side, since bulbs crap out faster proportional to higher filament voltage.

Good luck, Bill

The 850's are known for having bad dimmer switches. If you get one at a pick&pull, pull the small dash speaker out and then reach behind the extra long dimmer switch and push it forward.

In the mean time, try moving you dimmer switch around and see if that helps.

It could be a couple of things but most likely the light switch. Try to get one form PYP yard if you can.
