02 Montero Cruise
Help ... Looking for a direction for trouble shooting my cruise control.
Here is what the state of affairs looks like to date ....
1/ Cruise control indicator light on dash illuminates when cruise is activated - so it seems to maybe/possibly think it is on but my cruise doesn't work ...
2/ All brake lights etc are bright and function properly
3/ Brake switch seems to work right and be within specs I found in the FSM
4/ Vacuum lines and the (not sure what it's called) but the little control valve up by the throttle body/butterfly/accelerator contol holds vacuum
5/My next step I think is the servo/vacuum motor ... 4 pins in it ... can't find anywhere that says what the pins are/control and any electrical specs along with it ... how do I check to make sure it works properly on a Montero?
6/ If the servo works then the next is the control modules ... info? specs?
Any help, suggestions, similar things would be greatly appreciated ... no cruise on a long trip isn't a good thing.
Thx
Steve

Vacuum Servo ...
OK ... took the servo off ... I am not an electrical genius but unless someone can explain some other way it works ... seems like there is a short in it somewhere.
If I take it apart and strictly power the motor in it ... motor purrs like a kitten
BUT
top of servo
looking at plug (can't find any wiring diagrams for it)
xxxxxxxxxxxxxx
x x
x 1c 2c x
x x
x x
x 4c 3c x
x x
xxxxxxxxxxxxxx
2&3 appear to power the motor but when I it's all back together and try to power it via those two connections ... doesn't sound very good ... motor struggles (remember worked fine when I powered it direct when apart)
Resistance across connections
1-2 60 ohms
2-3 60 ohms
3-4 54 ohms
4-1 54 ohms
1-3 109 ohms
2-4 6 ohms
They are all open across all of the terminals ... that shouldn't be possible should it? as there would need to be some barrier for switching - like I said not electric guru but this doesn't seem right?
That would explain would it not ... why the motor runs fine when powered direct but reminiscent of a sick cat when I try to power it thru the plug (shorting out?)
