I have a Volvo C70 t5, 2008, with around 125,000 miles. Whenever I try to push the shifter to the right to activate sequential shifting/sport mode it does not work. The little orange light does not come on, and even if I try it won’t manually shift. The cigarette lighter does not provide any power, and I was thinking they could be related since they are right next to each other. If anybody has an idea let me know, anything helps, thanks!

Just found a good video on how to fix this issue. that YouTube vid should explain everything. Hope it helps
