I've been having cooling system problems with my '95 RRC, short wb. It has the stock 3.9, the auxiliary (condenser) fans both work, but only when the AC is on; I've replace the fan switch with a new unit; there are no leaks in the system, no pressure loss in any of the cylinders; heads have been remachined and are not cracked; I performed test G, per the electrical troubleshooting manual(ETM), up to step 3 where it failed. The ignition switch was in position II, but no fan action, if I let the motor run, it overheats. The ETM says the problem cause is the BP and B wire, but I'm not sure what that means. Does this mean the Fan Control Module needs to be replaced? Also, does anyone know of a supplier in the States, other than the dealer? Any insight would be greatly appreciated.
