Does a 1990 bmw 325is have a sliding sunroof

yes it does... i have 1990 bmw 325i and it tilts and slides back

I Might be wrong but sometimes then sunroof and shade must be lubricated every few years. maybe thats why it wont slide up but depending on the option the first owner put into the car. some sunroofs in these models do slide back and some just til.Because the moonroof is glass the interior parts get extreamly hot under the sun light, this might be the problem.
