You asked about grounds, there are (2) ground points associated w/ those accessories, they are located at:
Ground point G200: behind drivers-side lower kick panel, ground ring mounted to frame behind / below passenger cabin fuse box,
Ground point G102: parallel to & immediately to the right of the Driver's side headlamp assembly: follow the wiring harness above the headlamp -> to the side of the Driver's headlamp, - you are looking for a 14 gauge (black) wire that exits the harness, trace that wire down alongside the headlamp assembly -> to the ground ring & bolt, located on the driver's side fender, about 5 inches down from the top of the headlamp assembly,
Also recommend cleaning these ground points:
Neg. battery cable to ground tray,
Ground tray -> engine ground strap,
Ground tray -> frame bolts: remove battery, lift plastic cover, there should be (3) or (4) bolts securing the ground tray to the frame: clean up the bolt threads & bolts: replace w/ stainless bolt hardware if badly rusted, sandpaper or steel-wool all ground rings clean, use a thin coat of dielectric grease on everything when re-installing.
Hopefully inspecting / & cleaning up these ground points will help,
