The car was fine last night, but when I turned it on this morning it wouldn't blow any air, hot or cold, from the vents no matter where I set the controls. If I set it to say, 27 degrees, and put the fan up full, nothing comes out but the fan speed indicator counts up to where I set it, then back to nothing, then back up to where I set it, and keeps doing this as long as the fan is turned on. Is this likely to be the blower itself, or the climate control module? I've no access to VAGCom to read codes or anything unfortunately. Air con is gassed up and was working perfectly yesterday - but even in economy mode or on hot settings, the same thing happens! Thanks in advance for any help!
