Lately it has been raining and felt some lectrical problems occurring, recently rear tail light went out. The high beam wouldn’t turn on on one side. Check bulb and fuse, it’s still good. Could I have a ground problem?
Have you had any water intrusion through the cowl vent? Very common that it gets plugged and backs up into the cabin, right onto the smart junction box in the passenger side panel. That will cause lots of electrical issues like those you describe.
