 Bmw 318ti cooling fan new question
So I'm new to BMW but I have a new cooling fan question. So I bought my daughter a 318ti 1996 it has a 143000 miles and automatic. Here's the problem the fan only comes on with the a/c wait but it comes on with the a/c on and the fan is on LOW. I can jump it with the plug and a wire to her high fan speed but that's the only time there is high fan and there is only low fan with the a/c on. There is no fan with no a/c. Any help would be greatly appreciated. Oh yeah we did replace the whole cooling system i.e. Radiator,water pump,thermostat and housing and houses. Thanks again |
