Problem: The wipers work on low, the water pump works, but it doesn't work on high. Just had the motor rebuilt and replaced the ignition harness. I also replaced the wiper switch. The high speed still doesn't work. These are the wiper switch wires.
OFF DB 12 V bl/wh-0 Volts LB wire 12 v
low speed DB 12 V Bl/Wh-0 LB 0 wire
high speedDB 12 V BL/Wh-0 LB 0 volts
It's my understanding that the Bl/Wh should have 12 volts on high speed???Is that correct??
If so, where is the problem--the LB wire??
What and how should I proceed?
Thanks

Phisically verify the GND to all of these, Wiper Switch, Headlight sw.,
Console and gauge cluster, Tach and Speedo housing.
ALL of these must be GND. worst Electrical design ever, for a fiberglass car.
The (Engineer) who was responsable for Approving the wiring design to assume,
you have good Gnd. via conducting thru the componets housings, shoot have been fired.
