My 2004 durango 5.7 hemi AWD . 120,000 miles only been in high or low 4x4 mode before . I was trying to find out why my AC clutch would not engage this summer inless i jump the relay . Well i didnt figure that out yet .Then i started the durango to move it And the light in dash says SVC 4x4 and when i backed up it now in 4x4 mode . I never touched anything with AWD or 4x4 system . Now i can not get it out of 4x4 mode . I need alot of help please .
