For the washer ****, there's a little notch in the **** that you stick a small screwdriver in a pull toward you.
For the light ****, you'll reach up under the dash and feel for a little button on the light switch. Press the button and pull the **** out. The shaft will come out with it.

For the wiper you need to either reach under the dash, or pull the instrument panel out and on top ofvthe wiper relay there is a button you have to push, the whole *** and rod will come out. For the light there should be a screw on the bottom ofvthe **** or just pull it should pop off, atleast thats how mine is

Thanks for the replies, we got it while I was waiting for an answer. Though I do have another one, any particular place you can stick a volt meter or any other reader to see if power is getting to a bulb vs. the bulb being blown?

What the heck are you talking about? All this info is totally wrong!The wiper **** has a spring steel clip within it that retains it to the wiper switch shaft. The shaft is made as part of the switch, does not come off.
Below the clip, the **** has a notch in it. All it takes to remove the **** from the shaft is to 'trip' the clip using a small blade screwdriver.
At the bottom of the headlamp switch is a spring loaded button. Press that in and while holding it in, the **** and shaft (it's a one piece assembly) can then pulled from the switch.
To place the **** and shaft back into the switch, line it up and push it back in. There is no need to push on the button.
Since the OP has a 1979 F150...
