CENTRAL LOCKING "PULSING" - can you help?

[Guest Close Guest]

Whilst I am trying to find answers to my ignition barrel problem posted elsewhere, I may as well try to get some answers to the following equally annoying issue.

My 1998 Prado central locking "pulses" if that is the right word intermittently. The door locks don't go fully up and down but there is movement of sorts. I have taken all the inner panels off and can find no loose connections or other obvious faults. It does not happen often but when it does the only way to stop it is to lock and unlock the doors either via the key (outside ) or switch (inside whilst driving). On several occasions I have returned to the parked car to find it unlocked?

Any thoughts ?

Cheers and thanks in advance Ian

Re: CENTRAL LOCKING "PULSING" - can you help?

Coming back and finding your 90 series unlocked is quite a common experience. Mine also used to pulse like you say, havent heard it for several years now though.

I found the secret to my situation was to lock the car via the rear door, that seems to "reset" everything and I would have no further problems for some time. Then eventually I would come back and find the car unlocked, so I would reset it again.

I havent had any problems now for well over a year, but interestingly enough just last week I went to lock via the passenger door and only it locked, all the others remained unlocked. That was reminiscent of what also used to happen when the doors used to unlock by themselves. Perhaps the problem might be resurfacing again.

Its frustrating and symptoms seem to vary slightly from vehicle to vehicle, but I know of quite a few who have found the back door holds the key :wink:
