I have a 2001 Montana and my headlights are very dim, I have to drive continously on high beams, does anyone know why? or got advice? Also on my drivers side headlight cover, there is a small hole in it, when it rains water accumulates inside, I have dried it out and sealed the hole, however my parking light and blinker don’t work, when my husband took it apart the wiring for the bulbs was burnt beyond repair, anyone know how to fix it?
