Window Regulator or Motor W124 300E

[d2bernhard]

Hello,

Looking for opinions.

Car is the 1986 300E and has 208k on the clock. Driver’s Window is slow down and normal going up. If I put pressure down on it to ‘help’ it it goes down as fast as the Passenger’s ‘known good’ window. If stopped part way down, I can move it up and down about an inch.

Is this the regulator or the motor?

Thanks!
