Good day. I have a Toyota Corolla, 1991, 1.6 GLS (AE92). Just recently there have been issues with the cooling fan. When the thermostat switch is connected, the fan will not come on at all. When disconnected, the fan works continuously. I removed the thermostat but still no change. The heat gauge also remains just below the halfway mark, but the radiator will start to overheat and blow the cap off the overflow bottle. I also changed the fan relay which I noticed is getting extremely hot. Could the problem be the relay or the thermostat switch?
Thanks for any advice.
