That sucks. I’d restore it. Ya there a light to the DEF square on the floor. And yes, all three on the HVAC like you said.

Get a set of factory manuals. Lots online. 3.2 are easier than the sc diagrams but it’s all the same.

The black plastic light holders may me broken but the should fit in the recepticle the panel.

Seat back, feet back, and head under dash works. Taking the seat out is easier.

Also, look at your ignition ring and see what’s been added.

If you see a 4 pin connector up in there going no where and have manual pull heat, that’s the auto heat option.
