Removing/Installing ignition switch

I need to replace the ignition switch on my 78 chevy blazer. I'm currently using a start button but it has fallen apart so I want to fix the colum switch. How do I go about removing the switch?

I'm thinking of buying a new one and looking for decent replacement or possible remote starter switch setup.

It's on the top side of the column just under the edge of the dash. unbolt it and unplug it, watch how the rod from the key hooks into it. There is some adjustment when installing the new one.

fourbyfourblazer,

Do you want to remove the key part or the electrial switch at the bottom of the steering column?

The key one is kind of tough if the problem is the pinion gear that broke at the end of the key, that pushes down on the rod, that in turn slides the electrial switch to connect the start circuit.

And if it has a tilt steering wheel it gets even tougher, BUT it can be done.
All the parts a available at the dealer for around 45 dollars. You will get new bearings for the column and the pinion and rack assembly and a new return spring. Read and follow the directions and you will have no problems.

Good Luck
Scholman

The switch works as if there was a key in it but it doesn't appear a part of the key is inside. It doesn't look like it was pryed with anything. There is some black sealant inside the key hole.

So this would mean the electrical switch is working then?

I'm using two bare wires at the moment to start the blazer after turning on the key mechanism. It doesn't have tilt steering.

Try adjusting the switch under the dash. Sounds like you need the key actuator assembly, and possibly the switch.

If it's the cylinder call several locksmiths and price out Briggs & Stratton ignition cylinders, GM locks are made by briggs & Stratton and will be alot cheaper than buying from GM. the only difference is the box, the one in the GM box costs alot more !

BTW. wholesale price here is $10.00 to $15.00.
