Hello, apologises if this has been mentioned before but new here and have kinda run out of options or ideas to what my issue could be. I have a mk 5 2004 Golf with climate control and my blower only seems to work when on recirculate. I can hear the blower working normally but nothing comes out of the fans, however when i put the car into reverse the blower starts working but stops again when back in first gear. I ordered a new blower resister but turns out mine doesn't have one of these. Any ideas would be great as i have no idea where to start. Thanks in advance!
