How remove windscreen motor p2 h10 1937

[P27]

We have found the battery leakage !! It's the windscreen motor which has power going to it even when ignition is off!

It doesn't work/operate, but it warm to the touch. Disconnecting the wires solves the battery leakage. But how to remove it for inspection/repair. There doesn't seem to be much info. in the repair, or spares manuals, nor the electrics book.

Does anyone recognise what make/model this is?
Where is it in the electrics diagrams?

And should it have power going to it even with ignition off?
Could it be the gearbox/parking mechanism that's stuck!

I wouldn't have thought it would have power to it with the ignition off although I'm happy to be corrected on that. Delving into the wiring diagram would tell you. Likely it's been incorrectly wired up in the past or there is a short in the loom.

Hi,

My ‘37 P2 has the motor mounted differently but looks very similar in type.

Looking at your picture I’d suggest that the black metal surround is probably the mounting and the rusty screws that can be seen at the side hold the motor in place. However, it looks like there is a rubber pad between the two, which has deteriorated badly, sticking it all together. As such I reckon you will need to take the whole lot off the bulkhead to get it apart. Hopefully, there are mounting nuts you can access from behind. Good luck with all that!

Re the wiring; check the diagrams. It’s been a few years since I re-wired my car but I have a feeling that there is power to the wipers with the ignition off. I say the wipers as, if it’s anything like the earlier models, you have two switches, one for each wiper and the motor runs until they are in the parked position. There are contacts within the wiper bar mechanism behind the dashboard. It makes more sense once you get it apart. All that said, it is possible that your wiper motor is ok and that the wipers are not correctly parked and switched off, which could leave the motor running. I always thought this was a clumsy arrangement and I wired my wipers to the ignition switched live in the fuse box. Basically you have two fuses, one for auxiliary items like lights, wipers, horn etc and one for ignition switched items like trafficators, brake lights, panel lights etc.

I’m talking from memory here and it’s been a few years but we’ll worth you familiarising yourself with how it’s wired. These cars are pretty simple once you get to grips with the diagram and colour code on the wires.

Tony.
