how hard is it to change steering column?

[jasonroman]

when i bought truck the column had some shake to it. and the blinker part was cracked. the arm that controls the turn signals...= blinker part
since having the truck, if i pulled the arm to say, put on high beams, i would loose all lights..??
then last night went to get in truck and go to work. and no headlights.
i tried pulling the lever and nothing would happen. but i didnt hear the thing engaging like i would in the past. at the point where id loose headlights.
so im thinking i might want to start looking for a new column.
to get rid of the wiggle and have no broken blinker arm.

also wondering what i need to do to get the water to shoot on my glass??
wipers work. but no water action. tank is full, just no squirting/.

as always, thanks for any help
