When the AC is turned on and the switch in the RUN position, the fan should come on. The AC relay is likely the culprit. The fan is cut on through that relay by the computer. Only the old 87-90 Renix Jeeps had the coolant sensor tied directly to the fan... I think. It probably went through the relay also -- I forget how mine was originally connected! -------------- Date: Sat, 18 Aug 2007 08:55:10 -0400 From: "edwin atwood" <javelinsst@xxxxxxxxxxxxxx> Trying to trouble shoot electric fan in Cherokee.
