We are a team of ASE certified mechanics that have created this guide to help
you save money while doing the job yourself, or at least see what you are paying
for when having the job done at a shop. A turn signal switch is designed to activate
the directional signals either right or left by the driver when desired.
What Goes Wrong?
The turn signal switch is made of several plastic parts and electrical connectors
and may or may not be constructed with a wiring harness. When this part ages the
plastic can become brittle and crack or the electrical connections can overheat
and melt or become corroded stopping the switch operation. Mechanical failures can
cause the switch to not cancel after the turn has been completed. A bad turn signal
switch may cause the brake lights to
stop working as well.
What Does it Cost?
A directional or turn signal switch can cost between $24.00 and $130.00 depending
on design and configuration which can be purchased on Amazon or RockAuto, labor
time at the shop will range from 1.5 to 2.5 hours, if exact times or procedures
are needed you can ask our experts to supply you with
the information (free), or consult an online resource such as AllData DIY (pay),
this guide and video will be sufficient in this specific case. In some cases the
steering wheel will need to be removed
so keep that in mind when doing the repair.
Lets Jump In!
If you have a ignition switch off there is no danger of blowing a fuse when
performing the repair, some mechanics like to
disconnect the battery when doing
any kind of electrical repair. In the example below the steering wheel needs
to be removed before the job can be done, the
airbag must be removed first.
The steering wheel removal
is next, on this application the steering wheel will slide off without the need
of a puller (mostly European vehicles). If there is a question as to which style
your car has please ask one of our experts.
Beneath the steering wheel the electrical system clock spring or spiral
wire is next, this part is designed to facilitate the steering wheel controls
and horn operation while the wheel is in motion, it can be held in place by
using mounting screws which will allow you to
remove the clock spring.
There can be a retainer plate and fascia pieces that need to be removed
to access the turn signal switch, this will vary and may not be needed for some
applications, simply grasp the pieces and remove them, they should pull right
After removing the retainer plate mounting screws use a small screwdriver
and gently pry the plate from the column, it should lift straight off.
Watch the Video!
Please watch this video of the job being done, then continue down the guide
to glean additional helpful information.
In this particular application the cruise control switch is attached to
the turn signal switch. remove the mounting screws and remove the cruise control
switch to gently pull it from the column.
The directional switch is now exposed and ready for replacement, loosen
and remove the turn signal switch mounting bolts or screws, in this case the
switch is held in place by a squeeze clamp.
Gently grasp the switch and column bowl assembly and pull it outward to
remove it from the column.
Once the switch has been removed, inspect wiring connections and terminals
for corrosion, some turn signal switches are designed with a wiring harness
attached which will need to be disconnected near the bottom of the column before
From the backside of the column bowl remove the switch mounting bolts using
a Torx or screwdriver, this will allow you to change out the switch.
Remove the switch from tjhe steering column bezel.
Compare the new switch to the old unit, they should match identically.
Reinsert the new switch into the bezel, install and tighten screws by hand
to avoid cross threading, then tighten evenly.
Gently place the bezel and new switch over the steering column, after pushing
the switch into place, insert and tighten the mounting screws or bolt(s). Re-install
fascia pieces, move the top plate back into position and gently lower it into
the column, reverse the previous steps to complete the job.
