Servo off, blower cold, radiator hot, battery light on…

Hello together! I’ve been having a problem with my Escort Bj.96 (1.6 16V 90PS) since then. On the ride suddenly the battery indicator light went on and the power steering is off. In addition, the blower only spits out cold air and the cooler temperature rises significantly higher than usual (it was not in the red area yet, but in the cooling liquid tank it was extremely grubbed up). I’ve been looking for a bit here and at least for the servo problem is usually a defective light. Aschine responsible. But what about blower and cooler? Can this also be related to it? What else could that be? I am grateful for any hint.
