've got a 1991 Toyota 4x4 truck with a 3.0 V-6 and auto locking front differential that is supposed to lock in when the transfer case is put into four wheel drive. The transfer case shifts into four wheel drive but I do not get the 4x4 light on the dash and the differential does not lock in. I've checked the vacuum hoses and the wiring and everything appears to be connected. Has anybody got any tips on how to go about troubleshooting this?
