CDL acting up (1 Viewer)

[herkfe]

My CDL is not engaging. I have already replaced the indicator switch (the pain in the ass to get to). I have the optional CDL switch installed (97' FZJ80) and it was working fine last week. I'd press the button and get my CDL light and ABS light...no problem. Now I get nothing when I press it. No lights, no clicking sound for the relay and no whirring of the motor trying to engage. I'm sure that the CDL is engaging in 4LO, but without the CDL light or ABS light coming on. What is going on? I've taken it out on some sandy roads and have fooled with it trying to get it to engage, with no success. Could it be one of the other switches or event the actuator? Any input would be appreciated. Thanks.
