I have a 1999 chevy blazer with 48000 miles very well taken care off like new recently while driving in a lower speed it seemed to be cutting out and has lack of power, well the check engine light came on so I stopped at autozone and the scan gave the code of p1875 4wd low switch circuit it still goes in to 4low 4high and 2high just fine! what is most likely the cause and the solution switch or solinoid????
