I have a 95 EX Auto, and I'm overheating while sitting in traffic. I changed the thermostat about three months back( upper rad hose is hot), changed water pump and timing belt yesterday, coolant is fine, both fans are working, except while I'm running hot. I checked my passenger side fan when the car was overheating, and it wasn't on. I turned the car off, and the fan came on. Do I need to replace a thermo switch?? If so where is it?? Is it the same as a temp sensor?? what about fan relays?? Where are they?? I know there is one by the under hood fuse compartment, but is that the only one??
