    The headlight, dimmer, and flasher switches on my 300 are all acting up. How do I get them out, I assume pull the lower dash trim, and do all work from behind? Looks like switches are attached with screws?

    You will need to pull the dash cluster as a unit. The switches are install from behind the cluster. Don't do w/ the cluster installed, its too easy to break something there is no room in there. Disconnect the battery. Remove the lower steering column cover and drop the column down for easier access. Not as bad as it sounds. Be very careful around the printed circuit board not to break off the connecting pins. If you need a highly detailed description on how to do this PM me.

    Having David Hill volunteering to help you is like having your heart surgeon volunteering to come over and help to trim your hedges! :D

    I'll add that our dashboard plastics are OLD and BRITTLE, so be gentle. And by now, it's likely that various screws weren't replaced back in 1979 when switches and bulbs were replaced, and some screw tabs are already cracked from overtightening (if they're not already broken off :mad: )......so I guess I've already said it: Go slow, wiggle and jiggle, but be gentle. Oh, the backs of your hands will look as though you've been trying to pet your neighbor's vicious, sharp-clawed cat, but it will all be worth it when your switches and bulbs are all working like it's 1970 again. :thumbsup:

    This is the back of a 1970 Fury Dash. With that car, instrument cluster has to come out as a unit. HL switch and dimmer in top row 1st pic.

    Thanks for all the help. I might have seen a cluster removal procedure in the FSM. What you're showing looks like there are tabs in the bottom, and screws at the top. Pull the screws, rotate the top towards you, and lift up and away. I have a new headlight switch, the rear half of the car doesn't have tails or side markers. Dimmer is spotty, depending on position. Hope to clean it with Deoxit, or similar. I see there is someone who rebuilds these on the auction site. Flasher, i don't know yet, must be dirty. Sometimes both sides flash, sometimes only one side. Depends on how you mash the button. I don't know how the little seesaws, buttons, and springs go inside. I do know they will jump to freedom if I open the switch.

    I have to change the steering box, which means dropping the column. A good time to do both jobs. I'll PM if i get really stuck.

    I removed the column. Makes removing the dash much easier.

    I was scared of it, but I think I see now that both the input and output shafts have a master spline in the serrations. With that, there should be no way to do it wrong. Hopefully, the Pitman arm will pop off without too much of a fight.

    You will need a real puller to take it off.

    I wasn't far off. The OTC 6497 looks like that.
