87 5kcst electrical/climate control help needed !!!!!!!!!!

[Al Streicher]

Instrument light booster, could be the "voltage stabilizer" on the circuit
card for the instrument panel. It looks like a ceramic square with a metal
tab out of the top with a screw through it into the panel. There are three
legs coming out of the bottom of the ceramic square. Leg 1 is to the right,
two is center(ground) and three is left. Measure voltage between 1-2, switch
on ignition, must read battery voltage.
If not, connect voltmeter between 2-3, should read between 9.5-10.5V. If not
replace.

Do the license plate lights work? Its all on the same fused circuit. I
assume you already checked that, but you may have missed it. Make sure
that all other lights in and outside the car work, as some of them are
connected.
I never heard of a instrument light booster, just had a look in ETKA
and couldn't really find anything. I have no clue how it looks like
etc, or how it would work?! How is the voltage regulator? did that
check out?
You might be looking at the hard to trace intermittent connections or
bad grounds.

Good luck
