100 Rear wash/wipe

[Lawrence C Leung]

Time to suspect the steering column switch. If you have a wiring diagram
and an assistant, see which pins at the relay (relay removed) should be
activated (12V) when you run the switch through it's positions. This
should be push and hold for the situations that require that (such as the
"wash" or single wipe mode) or in the detent for those positions. YOu may
be able to clean a dirty switch with Stabilant or somesuch. Also, check
the wires at the firewall between the stalk and relay/fuse block, and the
relay terminals within the block (stabilant helps here too).
