Hey guys, I just bought my first land cruiser I named "The Land Crusher" off of my fathers fj40. Anyways, I bought my fj80 with the 3f for $4,000. Said the diff lock was stuck on, but I drove it and realized it wasn't on. But the light is on and it wont engage. I have a switch next to my defroster switch that doesn't work and it doesn't engage in L. Any ideas on how to troubleshoot? Thank you.
