I have a 2000 Safari Continental my turn signals are malfunctioning. When I use the right signal they don't work but the left side comes on and when I engage the left signal they work. When I engage the bright driving the low beam comes on and visa versa. I've only had this RV since January and didn't notice this occurrence. History so far I've replaced house batteries and replaced several light bulbs along with putting LED driving lights since the old ones were very weak. Would appreciate any insight to correct the problem. I was told that a grounding problem could cause this if the lights are dim but they are all bright.
