hey everyone i have a 97 gmc sonoma 4.3 vortec and the 4wd shifter wont move, i looked at it today and i saw that it has a line to the tcase. this truck is not the model that has push button 4wd, its on the floor. i think the line is froze up and i was wondering how to get it out, i cant seem to figure out how to get the plastic cover off to expose the tcase is there a trick to getting the 4wd shifter off, anyone have a write up or know what i should do thanks
