My symptoms were a bit different but I'll relate my experience in case
it helps. If it's the same problem you're gonna be driving the Blazer
Disclaimer: this was on a 91 F150 w/5 speed manual and tilt column,
YMMV if you don't have the tilt. I can't say what the difference may
be with a auto tranny.
The "key switch" in the steering column operates a long shaft that
moves a selector on the "electrical switch" which is mounted to the
side of the column, under the dash. Mine broke where the linkage from
the key switch connects to the shaft. I had to disassemble the upper
portion of the steering column to access the linkage.
I couldn't figure out how to get the column apart so I ended up
removing the whole thing, thinking that was the way. I got the broken
part out, but only because it was broken and no longer attached. I
took the new part home and couldn't figure how to install it. The
secret was that the yoke of the tilt mechanism was held in the column
by two tiny ( I think it was two) allen head setscrews, Once I took
them out, it was fairly simple to disassemble the head of the column
and install the new acutuator. The replacement part is cheap,
considering how much of PITA it was to install. Now that I know how, I
could do it pretty easily...
I managed to find the invoice and part # for it (sometimes it pays to
be anal retentive, it's a two yr old invoice on a truck I sold a year
I plugged the part number into:
E9TZ3E715B $9.90 $8.32
Steering column - Housing and components - Actuator
Actuator 1987 - 1991
Have fun at the lake, I'm going dirt biking in the mountains...
