If you're really that concerned for safety reasons, go ahead an plug it as the rules allow. I'll take mine functional, since a working defroster is critical unless you plan to park it when it rains.
If you're not following the discussion on other boards, there's a recall and TSB on replacing the heater core on all e-30 chassis. I'm not running anything in mine at the moment, but was considering running ice water from the cool suit cooler through it. If it were up to me we'd keep the AC and dump the heater

You guys needing heat need to get the cheap three layer suits, I bet you could hike in Antartica in those things and stay warm
