W211 Defroster Question
The rear window defroster on the CDI I just picked up is not working. The light comes on, the fuse is good, and the relay is good (swapped in the one from my other CDI). Haven't yet had a chance to run a scan. What should I do next in an effort to troubleshoot?
Thanks.

Ran a scan. There is a stored code 9070. Says K75 cut off relay for interruptible loads is bad. Comes up under the battery control module system.
Would that account for the defroster not working? Here's some info on K75. https://www.motor-talk.de/forum/aktion/Attachment.html?attachmentId=697611
