Ok I hate to beat a dead horse but here goes another passenger grip warmer question. The grip warmers on my 2008 Venture have worked well in the past but now my passenger (wife) says they only work sometimes. By doing some testing I have learned that when the warmers shut off when the coolant fan turns on and they turn back on instantly when the fan turns off. I just put a new battery in the sled this fall. I have read that this problem might be caused by the Load Control Relay. Is this true?
