2nd Gen Tacoma 4x4 Not Working

Hey guys, I have a 2005 Toyota Tacoma TRD Sport 4x4 with 307k miles. Couple months ago in the summer my 4x4 stopped working. Since then I’ve replaced the front diff actuator, transfer case actuator, changed the transfer case fluid, checked the fuses and they were fine, and today I just got my new 4x4 switch and put it in the truck and it still doesn’t work. When turning on the truck the green 4x4 light still flashes even with the new switch in. What is weird though is with the old switch when I turn it to 4Lo it makes the beeping noise as normal and the 4Lo light starts flashing. With this new one it doesn’t do that. I’m getting frustrated with trying to find out what the problem is at this point. Would anyone be able to help me out and point me in the right direction?

The new switch is from carquest part number is FWC1032.

Another thing is that two of the contacts on the old switch were bad which I assume is the contacts for 4H since 4Lo starts beeping but to get into 4Lo you need to be in 4H and neutral first.

 

Check your limit switch voltages as outlined in the thread below and post your results so we can see where we need to start looking.
