Mercedes: 190E 2.6 left rear window, mercedes benz 190e, number search results

Question
My left rear window will not operate.  I had it checked and it isnt the switch.  I had the others installed and they are now working great.  How hard would it be for a rank amature to install a new window motor?  I was hoping to buy the parts and do it myself.  If not, who should I contact other than the dealership.

Answer
Answer:
The rear window motors can NOT be replace separately.
This is roughly an hour DIY.
