My car was parked for about four days. Went to use it today and multiple items will not work. Power windows, radio, fuel gauge. I checked the individual fuses and they all look good. Is there one fuse or relay that would control those items?

Hello,

It sounds like the BCM behind the glove box has gone out. Here are the wiring diagrams so you can see how the system works. I would get a used one and plug it in to see what happens. You might need to get it initialized at the shop which should run about $130.00.

Component ID A104, Body Electronics Control Module (ZKE IV)
Location Behind Glove Box

Check out the diagrams (below). Please let us know what happens.

Cheers, Ken
