Climate Control Fan

[SDST08]

I was driving home yesterday with my climate control on and sitting around 21C as it normally does. All of a sudden the fan went to full speed and would not change speeds. It ran at its full potential for 3 hours while I drove. I tried everything I could think of. I even shut the whole system off but the fan kept blowing???? LOL WTF

When you adjust the fan speed manually it shows on the digital screen thats its adjusting but does not change. Ideas?

The temperature still adjust according to what you select though, problem is solely to do with the fan.

Mine does this too every now and again. I just pull over to the side of the road, turn the truck completely off, then restart... then it works normally till the next time.
