Here's a 240 sunroof motor. 

I pulled it myself from an early 80's 240 around 2002 from Millions of Parts in Hollywood, Florida. 

Power sunroof was only available as a dealer install when purchased.  This is what Volvo used for the 240's. 

My daily driver 82 Volvo 240 turbo has the exact same sunroof motor installed.   I bought the motor way before the car and was saving it as a spare, but it's time.

The last picture is my actual car with same motor installed.

If I really knew what I was doing back then, I would've gotten the wiring harness too.  I was just a dumb kid with impeccable taste in cars.

I also have a 740 sunroof motor that I personally pulled.  This time, I took the full harness and the switch.   Let me know.  

This motor is complete but untested and not guaranteed in any way

Feel free to ask questions.
