Horn Contact Repair Instructions
For Part Number 262000010
Instruction #: 8000010049 REV 11/09
The reason this spring gets damaged is due to 12 volts of
power being passed through it. If you have cooked the spring,
the horn is wired improperly. You must use the black wire on
the column as a trigger wire for a horn relay. You can pre-
test this by grounding the wire that comes to the black wire
on the column. It should sound the horn, not spark and get
hot. If you need a horn relay… we have them.
1. You must remove your steering wheel and/or adaptor.
2. Remove the snap ring by prying under it with a scribe or
small screwdriver. (Figure 1 A.) Once you get under it,
just work your way around it. It should pop loose after
it is released from the groove. Now you can remove the
horn cam.
(Figure 1 B.) Please note: There is a spring
under these components. The spring is similar to a valve
spring, it will come loose with 65 lbs of force but only has
a ¼” stroke.
3. This is the plunger that we are referring to. You should
see it at the 2 o’clock position. (Figure 2 A.) If this item
is good, it would be sticking out 3/8”. It would be able
to move in under pressure until it was flush with the
surrounding plastic. On release it should spring back out
to 3/8” past the plastic.
4. You could use any pliers but the side cutters give the best
grip. You are NOT trying to cut this, just pry with them
and use a pulling motion to remove the plunger.
(Figure 3
B.) This is the spring that could be the problem. (Figure
3 A.) This spring should be one piece and not discolored.
If this is burnt, you may need to use pliers or tweezers to
remove all pieces of the spring.
5. To reinstall, set the spring in first, then set the plunger over
the spring and center this over the hole. Using a hammer
and punch, tap the pin back in place.
(Figure 4) This can
be difficult. If it is being difficult, you can lightly sand or
file the lead edge of the plunger to make it start easier.
Installation of Plunger and Spring is complete

6. Set a piece of tube with an inside diameter of ¾” over the
assembly to compress the spring. Note the column shaft
must be supported at the bottom of the column to do this.
We stand the column on the floor, and push down. You
may have to use other methods if the column is installed
in a vehicle… maybe a floor jack under the bottom of the
column. Some times a helper is necessary to apply and
hold pressure to the bottom with a pry bar. The amount
of force is approximately 65 lbs. When you get this done
you will hear a snap as the clip goes in.

Installation is complete (Figure 8)
