Good Morning All,

Apologies for my first post being a request for help, but I really have drawn a blank on searching for the answer for the last few days.

I have a (87) 944 Turbo which has an annoying problem. The boot release motor won't cycle. It only moves when the release button is pressed, this means that if you don't get the motor to stop in the correct place the hatch will not lock shut - so inevitably you end up using the key. (which works very well!)

So far I have, cleaned all of the locks the catches, and changed both the switch and motor with a friends car to confirm they both work.

On a separate note, when I plug the motor into the other 1987 Turbo it resets itself to the correct cycled position. In my car it does not move when connected.

I am assuming that there is a relay that controls the cycle on the motor, but for the life of me I have no idea which relay it is, or where it is - it doesn't seem to be listed anywhere

Car is too early for a microswitch to come into play.

Any help is greatly appreciated, it is really annoying and as both motor and switch are working as they should it must be either a wiring fault (I have checked wiring colours and locations in connectors on both cars) or a relay.

Thanks in advance for your help.

Cheers,

Tom

Sounds like it's lost it's permanent battery feed.

Just to update this thread, after some more digging around today I finally found the answer.

On my friends 1987 Turbo, if I removed the fuse the motor does exactly the same as my car.

However my fuse is not blown, so i lifted out the fuse board and Fuse 1 (the fuse in question) has been spliced into two further fuses that must relate to the cobra aftermarket alarm that was once fitted, presumably with a boot pop from the key fob!

TBH I think removing the remains of the old alarm system is probably more hassle than it is worth so for the foreseeable future it will stay as it is. I can still press the button to pop the boot. I just need to make sure that at some point before closing the boot again the catches have been reset using the key. Or I can just use the key!
