Trying to do as much as I can on the 89 190D my friend just bought before I send it over to my mechanic. When I got the car I observed that the climate control was completely non-responsive. Seeing that the blower motor fuse was blown, I replaced it. Still no response from climate control, but I noticed that, when I turned the fan on, there was some current draw (the lights dimmed).

From that symptom alone, can I conclude that either the blower motor and/or the regulator is shot?
