Electrical problems
Hello I have an american 98 E320 and was wondering if someone could help me diagnose this problem i’m having, so my rear right taillight first worked but only the stand still lights then the standstill lights went out too with the brake light i’ve tried buying different bulbs and even switching them with the left side and still nothing i also just noticed the little circle light the one that turns on with the first click on the light switch also does not turn on with the side marker as well in the front. Anyone have an idea of what it could be ???

It sounds like you might be dealing with a few potential issues, possibly stemming from a faulty ground connection, a short circuit, or a failing tail light assembly. Given the symptoms, especially with the rear right taillight and the front side marker light not functioning, it’s likely that there’s a break in the circuit or corrosion at the connector. Additionally, the failure of the little circle light indicates that the problem might be more systemic, possibly involving the SAM control module, that manages the lighting system. I recommend running a full system scan as soon as possible. There should be fault codes stored in one or more control modules related to your lighting issue. Look at both Front SAM and Rear SAM. If you're not comfortable diagnosing it yourself, a mechanic can help. However, if you want to tackle it on your own, consider getting a full system scanner, like the youcanic full system scanner, which is excellent for diagnosing all vehicle systems. Just make sure to use a comprehensive scanner; some only read limited systems, and that could leave you without valuable fault codes.
