After no clear guide on options for fixing this common issue, this was created.
First, check fuses and see if any are out. At times other fuses and issues trip more issues.
If all good, check circuit breakers located under dash on drivers side.
Circuit breakers labeled: (Power) 30A and (Automatic Shoulder Belt) 30A may be tripped. This is a simple fix. Just by sticking a toothpick or needle in hole located on circuit breaker (see 2nd photo). If it clicks, it may have been tripped and you journey may end here, if not then continue.
If you were like me, it was not as simple as a fuse or breaker. You may need to check your wires coming from the switches on the door, specifically in the door jam.
Due to age and wear, you may have a tear (mix-tape dropping soon). OR like mine, many torn wires.
Here you need to remove the rubber cover and may need to push wires through kick panel to work on/check wires.
As shown, wires break and simply reconnecting them will restore your windows, seat belt, and/or lock issues.
Make sure to reconnect and reassemble everything. Hope this guide helped!
