I replaced a turn-signal switch on my 1957 Chevy 3200 P/U and reassembled, but the turn signal lever does not lock into place up or down. Any idea what might be missing from the assembly? I've been looking around the web, but can't find a photo that shows what might be wrong with mine. I even compared the reassembly to photos I took before disassembling. Any suggestions? Thanks, Damon

Not sure on the trucks but on the cars there is a thin metal spring that the center piece rides on that locks it in place. It can be installed backwards and may be the problem.

Thanks

Thanks for the suggestions. It appears the assembly in my vehicle is a bit different. Here's a photo. Btw, I've never seen it work right in the short time I've had the vehicle, so it may simply be a missing some part.

The truck looks simular except the pawls are metal instead of cheap plastic.
I think your missing the flat detent spring. It's the bottom one in the drawing labeled #580 Turn Signal Pawl Kit. The notches in the flat spring detents the lever in the different positions.

If you don`t have a shop manaul for it you need to get one. The passenger manual has a couple of good shots of that area. The truck manual probably does the same thing.

I had the same problem with my 57BA and it was the flat spring mentioned above. The photo is blurry, but it is on the right side between the pawls. if you look at the center of that area you will see squiggles in the flat piece. At the very center of the piece and to the right is a small post that the squiggley piece is supposed to go behind. My pic is the before and I had the same problem where it would not lock/click when engaged.

I dont know if you figured out the issue with your turn signal not locking, but you are missing a couple pieces. Here is a pic of what the turn signal cup should look like. Also, a little hard to see but if you look under the screw in this pic there is a thin piece of metal running across the cup under the lever itself, you are also missing that.

Thanks

Thanks for the confirmation. I actually do have the flat straight piece of metal (just doesn't show well in the photo). I'm definitely missing the spring though. Almost all of the wiring has now been replace and my signals work if I hold the level in the up or down position, since they will not stay there on here own. Once I get the spring piece I should be fine. Thanks again

Where can I get the spring to keep turn signal in the off position
