idosubaru Posted March 16, 2014 Share Posted March 16, 2014 1988 XT6 manual FT4WD transmission. DIFF LOCK is coming on while driving. The diff is actually locked and the light is on. The DIFF LOCK button works properly otherwise (meaning it'll turn off if the DIFF LOCK is off). Vacuum hose or solenoid/electrical? Link to comment Share on other sites More sharing options...
idosubaru Posted March 17, 2014 Author Share Posted March 17, 2014 Last night the DIFF lock would come on if i revved the car in neutral while coasting - happened a few times. So vacuum hose or the engine revving is tweaking wiring/solenoid i suppose. Link to comment Share on other sites More sharing options...
skishop69 Posted March 17, 2014 Share Posted March 17, 2014 The solenoid is mechanically weak or not sealing so you'll need to replace it. We used to see this all the time with EGR solenoids on Chevy's in the 90's. easy fix. Link to comment Share on other sites More sharing options...
