Got a used GP relay to replace an intermittent old one. Good news is the light pops right on (the old relay I sometimes had to smack with my hand to get it to reset). Bad news is it's little quick to extinguish the GP light. In other words, it's like 40 degrees here, and it pops the GP light on then off pretty damn quick, like instantly. The relay senses coolant temp right? Might the sensor be off? Remedy? It's a relay from florida. Maybe it's just acting weird like any Floridian that steps off the plane in Boston in March? I will try again today hoping for a longer GP burn and await your response. Thanks.
