Frontera B, petrol, 4x4 vacuum system

whats the problem you got, coz i doubt if they are at fault? have you tested them?

The bottom diagram is of the 2 to 4x4 shift motor, its underneath,on back of transfer box. it turned out to be faulty on mine. The vsv valves, if you connect up as in the diagram, and check by blowing down the tubes, to see if its switching over correctly, but id put money on the transfer motor assembly, they dont take to kindly to getting soaked and then not been used for long periods of time... Mine tested ok in my hand but wouldnt work in situ. so check it while fitted to the fronty too. Bet tthe valves are ok, let me know if you need anymore help. Know the 4x4 system like back of my hand now, after my problems.

pleased you got it sorted, can be real pain to find faults on our 4x4 system...been there done that :lol:
