CS5000 turbo quattro blower motor

[Richard Thomsen]

I have a friend who has a '87 CS 5000 turbo quattro, and the blower 
motor does not blow air (gets a little cold in the winter). He thinks 
that there may be a rats nest in the blower, but he cannot open it to 
get to the motor. He took out the dash and all the bolts around the 
housing, but cannot open the housing. He is considering using a dremmel 
tool to cut open the housing to get inside, but would like to avoid 
that, if possible. He is seriously thinking of selling the car if he 
cannot get into the housing.

Any suggestions?
