I was given a 2000 jimmy. Sounded great except the Drv side headlight was crushed, fender dented, the AC doesnt work, the headlights wiggle even after replacing both housings, there seems to be a electric problem with drv seat - makes quiet buzzing noise as long as ignition on, the front suspension makes pop sound when turning either way at low speed. Can anyone give me ideas on any of these issues? Thank you, Todd
