There to close to something thats interfering with them. Id say run them right down the center under the carpet or on the opposite side of where your powerwire is coming into the vehicle. ALso keep it away from where the cars accesory wires come into the cabin, any of these wires are the problem. Usually the right side of the vehicle is the best, but on some the center is better. Its just a pain to pull the seats out so you can run them down the center.

down the center console is usually the best idea because there is usually little to no factory wiring there. The best thing to do is plan where all your wires are going, then take a weekend to pull out the seats and whatever else to get done all at one time. You can solder and shrink tube or crimp the wires then tie wrap them all neat one time. You will have FAR less problems with loose wires after that.

Your wiring must be in a mess. Check it thoroughly for grounds.
