The short answer to you question is yes, eventually. The transmission fluid on the wires can harden the insulation on the wires which then cracks when the wires flex and at that point it can short out. The lights dimming and the wipers slowing are indications of a high power draw and add to that it gets worse when it's wet make it a lock that you have, probably, bad wires. Carefully inspect the full length of the wires. If you find cracked or worn insulation either repair the short if it is worn or replace the wiring harness if the insulation is at all cracked. Most likely it will be a major power line. Good luck.
