My remediation work continues.

I have a factory fitted rear locker in the Patrol. It's vacuum operated.

When I activate the locker, the dashboard locker light just sits there flashing & flashing. I wait for a few minutes & it still flashes.

I noticed this morning that there are 2 what look like vacuum hoses that cross from passenger to driver side & go under the exhaust pipe at around the front seat area under the vehicle. Where they cross from side to side they have rubber hose. I noticed 1 hose was disconnected, just pulled off somehow.

I stuck this back on hoping this may fix the flashing problem but it didn't.

Does anyone have any ideas on how I can go about fault finding this???

Thanks.
