i was running my truck in 4 wheel low and now it won't switch out, i turn the knob and don't hear any relays clicking. I thought maybe it was the switch and put a new one in for $40 and it still doesn't work. I didn't think it was the relay cause from what i see in the owners manual, the 4x4 relay is the same as the hazards relay and since my hazards worked i didn't think it was at fault. i looked at autozone.com and could not find a relay for the 4x4. any help would be greatly appreciated as i am stuck in 4 low. thanks
