Hi Jason, welcome aboard

I'm guessing you changed the fan because the fan is going full tilt, as well as the heat being full on. Sounds like the control unit's gone mad

I take it you're changing the fan setting and it has no option, and you've tried changing the temperature setting and that's done squat too...

First try disconnecting the battery for a few minutes (you'll have to reset the one-touch on the drivers door after, and you may have slightly rough and/or more responsive running for the first 5 miles or so). If that doesn't fix it, I'd suggest getting a new display off ebay...

If that doesn't fix it, you'll need to get the car in for diagnostics at a Peugeot dealer. Alternatively some of us have the same equipment at home and may be willing to help, so it may be worth putting your location in your profile
