Heating/cooling problems and blower malfunctions in the 2010 Ford Fusion: experiences and solutions

Hi, I had a similar problem with my 2008 Ford Mondeo. I'm not a mechanic, but I know a bit about it as I do all the simple maintenance work myself. When my heating/cooling was causing problems, my electric auxiliary heater was also faulty. I went to my regular garage and they quickly found the fault and fixed it. It cost me around 350 euros, which I thought was reasonable. To help you more accurately, it would be helpful to know if there are any symptoms, such as strange noises or error messages in the display?

Hey, thanks for your answer. So there are no strange noises, but sometimes the display shows me "engine fault". My current mileage is 123972 km, and my last service was almost exactly a year ago. Your €350 doesn't sound too bad at first, I think I'll take my car to the garage one of these days and ask about it.

Hey, no problem! So, with "engine fault" it could actually be the auxiliary heater, but only a diagnosis in the workshop can show this exactly. With your mileage, this could well be possible, especially if the auxiliary heater has never been changed. I would recommend you get it checked as soon as possible to avoid any major damage. Hopefully it's nothing serious and it won't cost too much. Good luck with it!

Thanks, it really sounds like I need to have a look at it. Exactly, the auxiliary heater has actually never been changed. I also hope it's nothing serious. I'll probably take the car to the garage next week. Thank you for your assessment and your well-intentioned advice!
