 Subject: Replacing Wiper Switch

Message:
I have a 2000 dak with intermitten wipers. I believe the switch is worn out because the intermitten part doesn't work any more. Has anyone ever replaced this switch? If so how do you disconnect it from the column? Thanks for the help.

Check the relay...and maybe fuse
² Continuous Wipe Mode - The two-speed wiper
motor and the internal circuitry of the multi-function
switch work in concert to provide two continuous
wipe cycles, low speed or high speed.
² Intermittent Wipe Mode - The internal circuitry
of the multi-function switch, the CTM, and the
wiper relay work in concert to provide an intermittent
wipe mode with multiple delay interval selections.
The CTM also automatically adjusts each
manually selected delay interval to compensate for
vehicle speed.
WIPER RELAY
DESCRIPTION
The wiper relay (or intermittent wipe relay) is
located in the Power Distribution Center (PDC) near
the battery in the engine compartment. See the fuse
and relay layout label affixed to the inside surface of
the PDC cover for wiper relay identification and location.
The wiper relay is a conventional International
Standards Organization (ISO) micro relay (Fig. 22).
Relays conforming to the ISO specifications have
common physical dimensions, current capacities, terminal
patterns, and terminal functions. The relay is
contained within a small, rectangular, molded plastic
housing. The relay is connected to all of the required
inputs and outputs through its PDC receptacle by
five male spade-type terminals that extend from the
bottom of the relay base. The ISO designation for
each terminal is molded into the base adjacent to the
terminal. The ISO terminal designations are as follows:
² 30 (Common Feed) - This terminal is connected
to the movable contact point of the relay.
² 85 (Coil Ground) - This terminal is connected
to the ground feed side of the relay control coil.
² 86 (Coil Battery) - This terminal is connected
to the battery feed side of the relay control coil.
² 87 (Normally Open) - This terminal is connected
to the normally open fixed contact point of the
relay.
² 87A (Normally Closed) - This terminal is connected
to the normally closed fixed contact point of
the relay.
The wiper relay cannot be adjusted or repaired
and, if faulty or damaged, the unit must be replaced.

Do you have the tool needed to remove the plastic cover from the steering column? If not, then the first thing to do is get one of those.

I guess I need to mention that sometimes the delay works and sometimes it doesn't. Most of the time it runs continuous when the switch is in the delay area, if that makes sense. So I figured since the delay sometimes works, it is a bad switch.
I'm not sure if I have the tool or not. What tool is required to remove the plastic trim?
