defrost on a ragtop?

[///M42 sport]

I tried it out the other day and smelled something burn lol. I guess it has no use in a convertible.

I'll get mine working some day and then tell ya :P

Mine has a blower behind the rear seat, where Jordan's subwoofer driver is. My question is how does it know that teh top is down? I don't see any switches.

[PanamaE30]

I don't think it does..

Why in god's name would you need the rear window defroster if your top is down anyways? :P

[parkerbink]

Don't need it, accidentally hit the button once, didn't hear the blower, thought it was broken, checked with top up, worked!

I therefore deduced it has a switch that disables it when the top is down.

Wow that's cool..

Maybe someday when i sort out all the electrical shit in my car I'll be able to try it LOL..

:(

thats weird, I don't have anything back there?

You do, unless for some insane reason the previous owner decided he was never going to defreost the rear window, ever again.

[mph]

Mine will stay on when the top is down. I have an older convertible and I don't think it has the switch.

It's behind your seat. Remove the rear backrest and you'll see a big horn looking thing.
