Parts questions

I'm looking at a pair of Euro headlamps and turn signals for my 92 300E. What's a fair price for these?

Also the sunroof on my car seems to be stuck. It will work in the tilt mode (up&down), however it will not slide back I can hear the motor running, is there a cable that could have broke?

Lastly the blower motor just went on the climate control. I see these for sale with or without dust covers what would you rec.?

Thanks for any help,

Brian
