Hello. My heater is just working in the maximum speed. On my local garage they told me that is the blower resistor. I bought one on ebay, part number is 6445.XE but on the garage they told me that one is not fitting in my car. They take out the broken one and is very different. Is rectangular and have a sticker with that numbers A521002400605500511 27.05.08 n.177748B i tried to find that part but I can't find it anywhere, I'm not sure if this is the resistor or not. I tried to post a photo but I can't upload. Someone can help me please? My car is a grand C4 picasso 1.6 hdi 2008 . Thanks
Tania
