I noticed that my 1994 348 is getting warm when I am stopped. I checked and the radiator cooling fan is not coming on. I jumped it out at the fuse box and it still didn't come on which makes me think it is the fan motor. Does anyone know how I can verify that it is the fan and not the temp switch? Should the fan come like the oil cooing fan does whether the temp switch is on or not when jumper out? Thanks for any help you can offer!!
