Radio Questions

[KSMITH1@mailgw.sanders.lockheed.com]

I have the pleasure of driving a recently purchased '88 90Q.  However, 
no radio information was provided with the sale.  The radio appears to 
be original.  Do any of this group know where I can obtain a 
xerographic copy or original of the directions for US radios?  

The radio has a liquid crystal frequency readout on the left-hand part 
of its faceplate.  This does not light up a night as I would expect, 
nor do the radio controls below it on that side of the faceplate.  
Should I expect it/them to?  If so, are the responsible lamp(s) 
ameniable to replacement, given reasonable electrical engineering 
skill, or are they embedded in the faceplate in the manner of avionics 
panels?

The AM portion does not function except for noise.  The "amplifier" 
(rear window heater/antenna interface) mounted on the left D pillar 
meets all voltage and current tests described in the new Bentley 
service manual.  Is that unit a likely cause, or is the radio itself 
more likely to be defective, based on historical experience?  (Please 
self suppress generic flames directed at Audi radios.)  With the 
amplifier-to-radio coax cable disconnected at the amplifier, and a 
wire connected to the coax cable center lead, one (presumably strong) 
AM station was barely detectable in the noise.

Thank you in advance for any responses.
