How to Fix Some Early Turn Signal Levesr That Won't Hold Position - On Demand Video

Most 1965 to 1976 models if they still function but lever will not hold. In most cases you can repair it yourself and save big $$$.

An annoying problem on many older Mercedes up to 1980 that have an aluminum housing surrounding the turn signal arm latching assembly. When these wear out the lever will not hold position when you push it up or down.  So every time you have to signal a turn you end up having to hold the lever down with your left hand!  Most shops will have you replace the unit and it is very expensive. On some models new ones are no longer available. Kent will show you how to fix this yourself using a dremel tool.  You will need a dremel type grinding tool with a very small grinding bit to complete the repair. No other cost and only takes 20 to 30 minutes.
