i have 03' e320 - w211 the fan (in the engine compartment) is constantly running at high speed, also it started yesterday after we got home from our trip. during our trip on the way home the ac was not functioning properly, the interior ac fan speed worked great, but the air was blowing cool, not ice cold as normal. when i got home i checked under the hood and noticed the ac lines were covered in ice. left the hood open so the ice would melted faster. it took a few minutes for the ice to melt ( live in florida ) and the ac began to blow cold air again but now the fan in the engine compartment is running at a high speed, constantly and will not slow down or stop. this has never happened before.
i can go out and start the car and within about 30 seconds, the engine fan kicks in on high and constantly runs. any ideas? thanks in advance for your response.
