If you mean the 55-6 switches, once the knob is off you need the hex shaped tool or a facsimile thereof which goes over the shaft to unscrew the retaining nut inside the bezel. The knob releases by finding the notch at the base and then inserting a small screwdriver to push up against a spring clip while pulling the knob off. On the tool, It is possible to make something using 1/4 hex but the tool is already made and easier to use with the handle. 51-4 and the entire bezel just unscrews. Once the switch is out you can unbend the tabs holding the phenolic terminal support to get to the interior. Be advised the rheostat portion and the contacts around the shaft is where problems with dash lights usually occur. The rotating contact pieces seem to oxidize and corrode quite easily. If the rivets are loose and corrosion has set in between the contact surfaces on the terminal pieces and contact plates they connect, it is almost impossible to clean around the pieces and have it last. The ceramic holding the assy is very brittle so I wouldn't advise trying to tighten the rivets by brute force.https://packardinfo.com/xoops/html/modules/newbb/viewtopic.php?topic_id=15649&forum=4&post_id=157339#forumpost157339
