I bought my retros off a guy on here almost 6 months ago. Worked perfectly fine since I installed them.

But over the past couple of weeks they've been extremely inconsistent. One day I was ready to drive home from work and they wouldn't turn on. Spent 15 minutes turning my car off and on and turning auto lights off then on then turning them on fully then off then auto off then on etc. finally they turn on. And now they never turn on unless I mess with the switch using the same routine. Some times it takes longer than other.

Wth is happening?
