Driving my 1980 308 gts’i’ last night and noticed the temp hitting the midway point and thinking it was premature to do so as it was cool out. As it drove it ticked passed halfway and started to climb. Pulled it into garage before it hit the 3/4 mark. Fans not coming on. I put a jumper between the thermo switch in radiator. They still don’t come on even with A/C on, which is supposed to turn one on. Radiator seems cool. So, I’m thinking it must be a water pump or thermostat. My question is shouldn’t the fans of come on when I put a jumper on the two leads? I checked the fuses and replaced one of the fan relays but still they don’t come on. Should I try a new thermostat or thermal switch before trying to dig into the water pump? The pump seems to be turning and the belt is turning. Ideas? Tips? Thanks..
