Ok so for about a week now I've been getting this odd electrical issue with my 90 GT only when it's raining (I live in Seattle so pretty much everyday that ends with Y). It started last Friday when I was heading home from work, the radio will cut out for about half a second and the wipers will stop for between 30 seconds to a minute and a half, and it will sometimes cause the car to shudder when the radio cuts out. I checked and cleaned the main ground and the 2 grounds on the driver's side fender apron and that didn't really do anything. It seems like a connector issue but I'm not sure exactly which one could be the culprit. Any help would be great
