Brake Abs Warning Light problems of the 2006 Dodge Ram 2500

I have had the abs system warning light on 5 or 6 times , turn signal problems- both turn signals work at same time, a/c problems with the compressor not working at times and now is out all together. Abs and the lighting issue is the biggest problem since it is a 2500 truck and I hall hay , tractors and a 30 ft 5th wheel trailer, people need to know what I am doing or can I stop.

The contact owns a 2006 Dodge Ram 2500. The contact stated that while driving 15 mph, the abs warning light illuminated as the brakes became difficult to depress. The vehicle was taken to the dealer for inspection where they stated that they could not determine the cause of the failure. The vehicle was not repaired. The manufacturer was notified of the failure. The failure mileage was 9,000.
