Robertcat Posted March 22, 2019 Report Share Posted March 22, 2019 I have a 48 D-24 town sedan. This car came with the original turn signal option. Recently it has been getting stuck after I push it up or down. The only way to free it is taking off the cap and playing with it with a screwdriver. I know I could always buy an aftermarket universal unit but I would like to keep the original look. Any advice where to look for a used working unit or someone who refurbishes the existing ones? Thanks. Quote Link to comment Share on other sites More sharing options...
Dodgeb4ya Posted March 22, 2019 Report Share Posted March 22, 2019 Make sure you have both springs shown in the picture otherwise it won't cancel or operate correctly... 5 Quote Link to comment Share on other sites More sharing options...
woodrow Posted March 23, 2019 Report Share Posted March 23, 2019 I have an issue with my turn signal unit as it will not stay in "neutral". it will default to the left, down or right, up position. haven't really noticed if the self cancelling works as I really haven't driven it yet. am I right in thinking that I have to remove the steering wheel in order to get the unit off to work on it? and is this a fixable issue or is it an indicator of being worn out. thx Quote Link to comment Share on other sites More sharing options...
Eneto-55 Posted March 23, 2019 Report Share Posted March 23, 2019 If this is on a P15, then the turn signal unit is an external device. (My car didn't have one - probably never did, so I cannot show any pictures.) If it is self canceling, then it probably engages a wheel of some sort mounted to the underside of the steering wheel. Maybe then you WOULD need to remove the steering wheel to get at it. But it may have a removable cover that would allow you to get some white lithium lube in there, or see what the cause of the problem is.

DonaldSmith Posted March 23, 2019 Report Share Posted March 23, 2019 My DeSoto has two tabs at the base of the steering wheel which engage the turn signal device and candel theturns. I presume that, for an aftermarket turn signal device of the time period, a sleeve with the two tabs could be pressed onto the steering wheel. Or maybe, the steering wheels came from the factory with the tabs in place,for future turn signal devices. Here's the best photo I have: 1 Quote Link to comment Share on other sites More sharing options...
Plymouthy Adams Posted March 23, 2019 Report Share Posted March 23, 2019 the aftermarket switch would have to be designed for self canceling...most generic units are not and are manual select...off/on Quote Link to comment Share on other sites More sharing options...
Dodgeb4ya Posted March 23, 2019 Report Share Posted March 23, 2019 (edited) You have to remove the steering wheel to access the T/signal assembly. As shown above those two tangs are what cancel the switch on turns...tangs engage the roller wheels To remove the plastic cover with the steering wheel removed you will find three chrome screws holding the cover to the switch assembly Edited March 23, 2019 by Dodgeb4ya Quote Link to comment Share on other sites More sharing options...
DonaldSmith Posted March 23, 2019 Report Share Posted March 23, 2019 Here's a close-up of the tangs: Quote Link to comment Share on other sites More sharing options...
ACJCF2 Posted August 3, 2019 Report Share Posted August 3, 2019 Thank you Dodgeb4ya, for the picture in #2. I have the same "Directional Signal Switch" on my '49 D30. I figured there had to be a spring or something for the two top forked arms to function with. My switch will not self cancel. Now, to find a suitable spring. 1 Quote Link to comment Share on other sites More sharing options...
