[DeTomaso] Headlights Not Going Up and Down

[Mark McWhinney]

There is no fuse shown on the power to the headlamp door relay switch (the
red wire).  Is there no fuse or is the fuse just not shown on the diagram?

Trevor,
 
 
Check Fuse #10 (third from the bottom). This fuse powers the  Headlamp
Motor, 
the AC/Heater Fan, and the AC Temp Control Switch. If Fuse #10  is blown the

headlamp doors will not move and the AC/Heater Fan will not  run.

you will find Page 1 of the diagram of the Headlamps and Doors circuits.  
The upper portion is the door controls and lower portion is the lamp 
controls.  The lamps are powered direct from the battery. Anytime the
headlamps are 
on, the  door relay will be energized.

you will find Page 2 of the diagram of the Headlamps and Doors circuits. 
This  diagram shows how the limit switches control the door movement and 
position. The  diagram also includes the Ignition Switch and Headlamp Switch

positions which  are required for each headlamp door condition. All of the
wires 
(and therefore  the voltages) pertinent to the motor control are accessible
at 
the limit switch  terminal.
 
The door switch diagram shows the sequence of door motor voltages  from
Doors 
Closed, Doors Opening, Doors Open, and Doors Closing. All of these  voltages

are available at the limit switch terminals.
 
In probing circuits where the connections are insulated, grind or  file the 
meter leads to a very thin sharp point and push the lead thru the
insulation 
of the wire. Be VERY careful not to give yourself a vaccination  while doing

the probing.
 
Hope this helps. Let me know what you find.
 
Have fun,
