The circuit that controls the windows/sunroof had become slow to
initialize after starting my e36. Eventually, it died altogether.
Many have faced this problem and I just wanted to take the time to post
a solution that worked for me.
Replacing the blue relay (underneath the driver's side dash directly
beneath steering column), also known as the "comfort relay", fixed the
problem. Anybody with a phillips screwdriver and about $35 (at the
dealership parts dept.) can pull this off and save some $$.
