I knew there was something wrong with your thermostat. Okay lets do the test and make sure your temp sensor is working. Do test # 1 above. You don't really need to remove the sensor from the car. Just unplug it and make sure there is continuity between the sensor terminal and ground when the engine is cold. Next warm the engine up and then do the test again and you should no longer have continuity between the sensor terminal and ground. If the sensor tests ok then we'll check for continuity of the wire.
So far only tested the fan switch. No continutity. The one that was on there before does have however, so when i can il put that back on and check the relays etc.
