Flooring on passenger side(especially rear) soaks up water like a sponge and traps it under the floor. Then, due to placement of many of the rear right-side fuse block and wires coming from it, the wires will pinch/rub/cut and the water-proof shielding to the wires becomes damaged, exposing the wires to corrosion. Resulting in minor to extreme electrical issues.
FIX: remove carpet after pushing seat all the way forward, then remove damaged wire sections and reconnect the wires.
Also note: another connector with many purple wires can easily become corroded which to my best knowledge can be repaired by using a wire-nut and connecting all the wires together.
