Oil temp/voltage gauges

["J. Smethers" <smethers@fast.net>]

Audi'tes,

I took advantage of the mild weather today to replace some bulbs in the car.
The cluster now has lights, greatly improving my nighttime speeding (ah, I
mean driving).  On another note, I replaced the two small lights in back of
the diff/volt/oil temp panel assuming that this is why I cannot read the
volts or oil temp and also why the two diff. lights never come on.  Nothing
changed, no lights at all.
Does anyone have any tips for repairing this problem?  Is the PCB replaceable?
Thanks in advance.

Regards, Jeffrey Smethers
