My driver and passenger seat aren't working. I can't recline or move forward or backwards. Please help!

Since both sides aren't working, we have to look at what they both have in common. That includes the 25-amp circuit breaker, and ground G304.

Start by checking for 12 volts on the orange wire at either switch assembly. If it's there, the best suspect is a corroded ground wire or terminal at G304. If the 12volts is missing, swap in a different circuit breaker as a first step. Let me know what you find.

I took off the seat cushion to gain access to the wiring harness and found a orange wire cut and two other wires that were cut and spliced back together with speaker wire. Unfortunately, I had to put the seat back together to go to work but tomorrow I'll be taking everything back apart and splice the cut wires properly and reroute the wiring harness so it won't get damaged again. Hopefully that will be all it needs. I'll definitely take pictures of before and after repairs. And send them to you. Thanks to all for the help. It is really appreciated! Ahhh, lunch break is over, gotta go. Once again Thanks!
