Noisy Air Conditioning fan

Post by cgwcmlw »

My 2015 C4 Picasso VTR Hdi with automatic climate control has a 'whistling' fan when the air con is activated. When heating ONLY is required, the main blower/fan on the drivers side operates but this is quiet so NOT the fan that is causing the problem. On investigation to locate this extra fan, from the whistle, it appears to be around the heater matrix on the centre console but nothing visually without a major disassembly. I presume this fan blows air through the air con evaporator. Any help on locating this fan in order to replace would be appreciated.
