Problem with car overheating.
Could somebody help me solve this problem? I had my thermostat and temperature sending unit replaced and now my fan won’t work and my car overheats. The only time my car will not overheat is when the sending unit is unhooked, and then the fan will start working. It’s like completely backwards. I’m going to take it to a ford dealer tomorrow, but I wanted to ask you guys and see if you have heard of anything like this before.
