Can anyone tell me what would cause the blinker to only be half lit?
A few years ago I pulled the cluster to fix the speedo gear and when I put it back in the right blinker was like this. I'm about to pull the cluster again to replace some burnt out bulbs and wanna try to fix this

 

My guess is that something got in there and is blocking the bulb. Possibly a small piece of plastic, or something else, got jarred loose when you had the cluster out. It looks like you can either live with it, or pull the cluster and clear the obstruction.

 

Ya that's what I'm thinking. Not sure how else it would be like that but you would think after a few years it would have vibrated out of the way. I'll be pulling the cluster in the next few days so I'm sure I'll figure it out

 

Well I found out it was a wire blocking my blinker bulb so had to take cluster apart and adjust it no big deal. When changing all the illumination lights I broke one of the 194 twist sockets. I can not find them on O'Riellys/auto zone websites. Does anyone know the part number for these so I can get my truck out back together today if not I'll be ordering a 10 pack off of Amazon
