I'm going to throw a couple more things into the mix that I didn't really  
think about before.  I went through the wiring diagram...again.  i  noticed that 
several things lead to the same ground:  panel lamps, heater  motor, wiper 
motor....I'm kind of brain storming here.  Earlier I thought I  made a great 
discovery, but now not so sure.
 
So, my panel lamps are not working and neither are the windshield and  signal 
switches.  I dont know if its related, but at some point I took the  heater 
out.  It wasnt working anyway.  I taped off the ground and  other wire. I also 
didnt have the wires plugged into the heater/fan switch  on the dash.  Is 
there something to do with a circuit not being  completed?  I tried plugging the 
fan switch wires in and I also grounded  the fan wire to the car since the 
heater is not in.  Do i need to put the  heater back in and plug everything in to 
complete a circuit?  It seems like  the fact that all these things that are 
not working now and were working prior  to my wreck should be related somehow.  
But i cant remember at what point I  took the heater out and if it made a 
difference.   
 
I also took a front light out and sanded the body to the metal where it  
bolts just in case that made a difference.  Nothing again...but I think  Paul had 
said the rear lights should have been glowing still anyway and they  arent.  
 
When I replaced the relay for the turn signals, the right one worked for a  
short time and the left one would blink sporadically.  Then at some point  they 
stopped working at all and would not even glow.  Seems wierd that they  would 
have even worked at all.  Could the relay have somehow shorted out  because 
of something else that is still wrong and thats why it worked for a very  short 
time?
 
Dont know if this complicated the issue but wanted to throw it out  there.  
Think I will likely be going to Harbor Frieght to pick up the  voltmeter.  
 
Thanks again for all the tips...steph
