Rear window elements do not defog rear window though switch light is on. I've searched in length for information regarding how to access connectors for rear window element and there is no information on how to remove rear post panels to expose terminals. I tried prying rear panels off this morning with a putty knife with no results. There is no relay in trunk that I can see, where is relay located and how is it accessed? This is a '95 E300. These cars seem to have a lot of electrical issues

Thank you
