Hi everyone. A month or so ago I had the aircon compressor and condensor on my 2005 Mk5 replaced by my trusted local garage. Everything was OK - aircon nice and icy cold again. However, now the aircon is working properly (probably for the first time in a year or more!!) I notice that occasionally the vents stop blowing cold air. I can turn up the fan to max, and it's definitely blowing a gale somewhere - but not out of the vents. For example, on a recent 2 hour+ journey in the blazing hot weather we've been having, we had icy cold aircon for the first hour - then the vents stopped working for an hour (fan blowing at max, but not out of vents) - then the rest of the journey with icy cold air again.
Coincidentally, one of the 2 LCD aircon indicators (the one's that say "LO - 16- 17- 18 etc") has recently started to break up (ie parts of the numerals don't show) - I doubt this is related, but mention it anyway - and I'll need to fit a replacement aircon module to sort it.
Any ideas about the intermittent blowing problem? Could it be both of the motorised flapper valves sticking (it seems unlikely that both would stick)? Or could the faulty dash module be the culprit?
