Miateers:

Last Friday, my driver side door speaker stopped producing sound for no apparent
reason.  Having just received my Workshop Manual, I proceeded to diagnose the 
problem.

Following the manual's instructions, I removed the speaker and check the 
connection.  It was fine.  I then checked the speaker (4 Ohms resistance).  No 
problem.  (I even swapped speakers and both work fine in the passenger side door
only!)  Next I did a continuity check on the speaker wires.  No sweat.

I was aghast at the next step in the manual.  It said "replace audio unit".  Do 
I really need to do this??  Could it be something else?  Has anyone else 
encountered this problem?

I have a '90 B-pkg with factory stereo.  No modifications anywhere in the sound 
system.

------------------------------------------------

NOTE: I wrote the above before I started my car this morning.  Guess what?  The 
speaker is working fine now!!  So, has my audio unit flaked out on me?

Thanks.
