I have a 2000 Dodge Caravan with 95,000 miles. I was driving in stop and go traffic and pulled into a fastfood drive up lane when the temperature light came on and the engine temperature spiked. I pulled out of the line and quickly popped the hood. The radiator fans were NOT working. I have checked the fuse for the radiator fans and it is also okay. I let the engine cool and checked the coolant level, which was fine. Once the temperature was back to normal, I continued driving the van. I have since been in stop and go traffic, but the engine has not overheated. I went to a local parts dealer and had them check for fault codes. Two codes came up. One was P1491 for a Secondary Switch Solenoid Circuit Malfunction which I believe is related to an airbag recall notice that I have not had repaired. The second code is P0118 - the input from the engine coolant temperature sensor is higher than expected. The parts place suggested I change the engine coolant temperature sensor - which I did. The engine has not overheated but the radiator fans do not come on - even when the A/C is on. Any suggestions before I do any further damage to the fan? - Could this possibly be a relay issue??
