I have a 1992 gmc jimmy s15 4.3L, 4wd, automatic transmision, vaccum line four wheel shift. my transfer case switches into four wheel when the light says 2 wheel and switches to 2 wheel when the light says four wheel . i have replaced the four wheel drive light switch, replaced the four wheel actuator. anyone knows what i should do? i still have yet to check the switch underneath to see if correctly put on.
