Hi - little problem with my front passenger door lock switch. For some reason, only the 'lock' side of the circuit works in that armrest. It is not the switch - I tested the switch with a multimeter, then when it cleared, jumped the leads in the block with a piece of wire. Again - 'close' works, but not 'open'. This means, as far as I can tell, that this wire has failed somewhere. I guess I will pull open the place where it flexes in the door jamb first. But at first glance nothing looks out of place, so I am wondering where that wire runs. Does it go into the passenger footwell, then behind the heater to the fuseblock in the driver's footwell? If so, I might just run a new wire.

But if anybody knows anything about this circuit, or has ideas, I would be much obliged.

 

I believe when I installed my alarm I grabbed the door lock signal at the driver side behind the kick panel. You can search the web for 4runner alarm wiring guides and you'll find door lock wiring.

 

It’s also not uncommon for door lock actuators you just give up. habanero has a write up where she replaces the little motor with one from eBay. I took a lazier route and bought a lock actuator from rockauto (it was like $25).

 

Thanks. I think it is the switch end because both locks close and open with the driver's side switch. And it locks with the passenger's side, but it doesn't unlock. Irritating!!
