Roof relay question

[geraintthomas]

Got a bit of a conundrum here.

I've come up with an idea of wiring up two delay-off relays for the open and close button on the dashboard for the roof. Essentially you'll be able to press the open button, the relay would keep the button active for a set time, then turn off. Same for the close button - making the button a one-touch roof system.

All is well and good, easy to wire in and cheap to do. But I've got a question.

When the relay for the open button is running, and the roof is opening... what would happen if I pressed the close button?

This is normally impossible as it's a rocker switch, but when I have two relays wired up, I'd be able to activate the close button, whilst the roof is still opening. What would happen?

This is the only thing that's stopping me going ahead with it.

Cheers!
