2005 Ford Expedition V8 Four Wheel Drive Automatic 90000 miles
I went to trade in my 2005 Ford Expedition. The dealer told me that my 4wd was not engaging. I just used it last winter with no problems. I did confirm that the 4wd light was not lit while in the 4wd mode. Looking back, I have never seen the 4wd light on the dash ever lit. I took this to my local Ford dealer and they told me that the 4wd was engaging, but the light would not illuminate. I then had them look into it as to why this was, and they told me the PCM board was bad. Would the 4wd work even if the PCM was bad allowing it to be in 4wd but without the light?
