sunroof issues

I have a 98 rodeo LS with a sunroof. Whenever I shutdown the car, the sunroof automatically closes, even if I have it up in the vent position. Is there anyway to stop this thing from closing?

Thanks

Sounds to me that there is an aftermarket alarm with window modules in your car. You can try disabling this unit.

no aftermarket alarm at all... actually i can't even operate the sunroof unless the Engine is On. I can't leave the key in the On position either.
Weirdest thing over the weekend was that when i shut off the car, the stupid thing opened into the vent position and I didn't even touch it!

The wifes 2000 operates the same way, key off, sunroof closes. Only way around it is to rewire it. Personally I lkie it this way, won't get soaked inside if it rains and she leaves it open by mistake.
