if the problem ended up being only water related, waterproofing the important electricals may be worth your time if you like to drive through snow banks. 20 year old weatherpack connectors don't always keep the water out anymore. Duct tape is easily removable and will keep the water out. I've had vehicles up to the hood in water without a problem with just a snorkel, a few rolls of duct tape, and a raised exhaust.
