4 Wheel Drive/SUVs: 4 wheel dr. light blinking on on 2006 jeep wrangler, jeep wrangler, ok book

Question
i checked the fuse for the transmission, it is ok, book says 20 amp yellow, it has a 20 am blue.  is this ok?  purchased Thursday, put less than 110 miles on it.  got in it today, drove about 8 miles and light started blinking on.  what could this be?

Answer
Lottie, it doesnt make a difference as long as its 20 amp. I would tell you to take it back to the place you got it from , and have them take a look at it . Its very hard to tell you whats wrong with it without hooking up my scanner to the Jeep , good luck ADAM
