Head lights fog light problem
So I have a issue that seems to come and go. It happened before, and cleared up. It happened again this weekend on a travel trip. I turned on my lights and the pass headlight was dim, less than half as bright as the drivers side one, on low or high breams. I also tried switching on my driving lights and they wouldn't work with the low beams, but did sometimes with the head lights on bright/high? I banged on the dim pass headlight, no change, moved the connector at the back, no change (still dim). Also, prior to the trip, I had to jump start it. I then drove it for over 3 hours to my destination in daylight on my recent trip and around with no issues. It started like normal the whole time over the weekend with no issues at all. Went out today after work and everything is working fine. pass headlight is bright again?
Some other info: Battery is old and If the jeep sits for a week or so, it will crank slow and wont start. Once, I charged the battery while it was in the jeep hooked up to the cables? Problem doing that? I've done that with many other vehicles with no problem.
