Hello, I have a 2007 Wrangler U that seems to have lost its mind when it starts to rain. Living in the Pac NW. rain is a constant part of life, however everything it rains my ABS comes on. Only when it rains is there some sensor causing this that I can't find or is it a computer error?

It could be a bad wheel speed sensor, a scanner should let you know about that.

Bad grounds will do that when they are damp/wet, start by changing the Junk Factory battery clamps to some HD clamps.

Definitely this - the battery clamps on Jeeps are some of the worst OEM ones I've seen and I had so many issues that tricked me until I fixed mine. My ABS/Dash Christmas Tree would come up, my wipers would randomly start/stop, horn would beeps, etc. I changed my clockspring, TIPM, and more. It was the stupid negative battery clamp that was stretched/distorted. It was making contact, sort of, and not loose to the touch, but after realizing that it was barely doing anything, a quick $10 fix eliminated all my headaches.

Seems like headlights and battery clamps are two immediate changes every Wrangler needs.
