Hi guys since the cold wet weather kicked off, my sedona 2006 old model (not garaged) sometimes fails to start as I get no pre heat light on the dashboard . Had this last happen in April and no problems up till now. If I switch off ignition and start again it will switch on the preheat and start ok. Sometimes several tries to get preheat light on dash.Once started it runs fine and do not have preheat light flickering as some have experienced with loose connection to preheater. Any advice on other connections or relays involved . many thanks in advance for any suggestions.
