My mechanic said squirrels may have chewed on my harness. VSC, ABS, 4WD, and brake warning lights stay on. When I pull out normally front wheels spin and squeal. I suspect 4wd is deactivated and only front wheel drive working. This was not a problem before work was done on car. A stabilizer bar was replaced. He said he tried to solder wires. Where do I find these wires?
