Hi brand new to caravaning. First trio out of 3 days and have a few issues. our fridge doesn't appear to be working on anything apart from light comes on. not getting cold at all and was told by previous owner the element had just been replaced!. also the heater this gets hot but the blower motor isn't working, any suggesting for this? I've tried looking through the threads but all seem to be about it not getting hot. ours does but can't hear the fan on at all. Any help would be appreciated as I can't seem to find spare parts either.
