2001 Mazda 4x4 no vacuum hubs will not engage in four wheel drive B4000
This vehicle has no vacuum lines for the hubs the hubs turn all the time it just does not engage the four wheel drive the tccm lights up when you start it but when you turn the switch it doesn't say anything unless it actually engages and sometimes it does when it doesn't engage the light comes on when it doesn't engage the light stays off when it does gauge I hear a clicking sound before it engages when it doesn't engage I hear no sound is there some sort of solenoid or relay switch that is not functioning properly between the switch in the inner cab and the transfer case I've checked all the fuses all the relays feasible links diodes everything passes as functionable should work but I cannot engage it all the time and most of the time it doesn't engage I know it has the transfer case motor which I have power going to I haven't bench tested yet but the reason I have it is because I'm not hearing the clicks it's got to be something engaging it and I don't know where it's at any help I can get I'd appreciate it very much thank you
