hey guys im new on here and i need some help i just bought my first truck (1994 f150 xlt with electric 4x4) my problem is when i bought the truck i couldnt switch out of 4x4 then out of no where it change on its own now the lights on the switch arent on and it doesnt even say on the dash if im in low range or 4x4 anymore. its the 5.0 302 with a e4od if i remember correctly i cant figure out what transfer case it is tho

 

93 XLT 5.0 - 4x4 auto switch on dash

Hope this is not a repeat... switch Part # F2TZ-14B166-A
When hubs locked (manual) push switch on 4x4 works great, engages, both lights on dash... when push "low range" nothing, not engaged, no lights on dash. IS this a switch or T case motor.. again ... it engages in 4x4 high just not low. and someone suggested it may be the T case actuator?
Thank you
