pyrie Posted January 4, 2020 Share Posted January 4, 2020 The cabin fan/heater stopped working on all 4 settings, and reading elsewhere I checked the fuse 8 in the engine bay. No problems. I checked the red relays, and swapped two around (same amp) . No fix. However. When starting the engine, the habitation fuse box now makes a stop/start warning noise. I think it makes the noise one-off if the habitation step retracts , however the step isn't out. Aside from calling a motorhome vehicle electrician, any thoughts on what has triggered the noise and which relay actually controls the fan? Doesn't help I check the fuse box during a wet drizzle day Link to comment Share on other sites More sharing options...
