2die4 Posted July 19, 2019 Share Posted July 19, 2019 (edited) HI guys I just drove my car to my friends picked him up went for a coffee parked up and then when I came back and started my car up the AC heating stopped working and started make a load whirring noise from the passengers side. Any idea what the issue could be as I have no air coming out of the two front vents but i do from the ones on the dash and weak air coming from the further left and right passenger air vents even if I try it hot or cold and a loud whirring noise when I take the fan speed past 1/4 strength getting louder as I take it to 100% . Thanks Edited July 19, 2019 by 2die4 Link to comment Share on other sites More sharing options...
2die4 Posted July 19, 2019 Author Share Posted July 19, 2019 update: i took it to the local AC guy to check if any leaks etc and there are none so I am guessing it is the blower heater unit will find out in around 2 weeks as i have it booked in for service then as well Link to comment Share on other sites More sharing options...
Founder Popular Post Beanoir™ Posted July 19, 2019 Founder Popular Post Share Posted July 19, 2019 Sounds like your blower fan may have packed up. I know you have a 987c but It’s not uncommon on the 981 for the blower motor to stick, particularly after a long spell of the car not being used (week or two). It can be ‘woken up’ with a simple prod of the fan which is located under the bonnet behind the plastic covers. 2 Link to comment Share on other sites More sharing options...
mike3105 Posted July 22, 2019 Share Posted July 22, 2019 The bearing on the blower on these is weak, you'd get a whirring when it finally goes, and the weaker air coming out adds up too. It's not too difficult to DIY, and there are always some of them on ebay (normally advertised as HVAC units - same as the 997 part) for about £15. 1 Link to comment Share on other sites More sharing options...
GlosRich Posted July 22, 2019 Share Posted July 22, 2019 Maybe also worth checking the pollen filter duct isn't blocked up with leaves, its under the plastic cover at the base of the passenger side of the windscreen, easy to access. 1 Link to comment Share on other sites More sharing options...
2die4 Posted July 25, 2019 Author Share Posted July 25, 2019 thanks for the responses guys but it was a bit of the heat shield trim or whatever that sits over the pollen filter that had broken and fallen down into the heater blower area here is a pic of it 1 Link to comment Share on other sites More sharing options...
GlosRich Posted July 25, 2019 Share Posted July 25, 2019 How could it get past the pollen filter? That bit of sheeting sits over it, guess it stops too much water going into the pollen filter. Link to comment Share on other sites More sharing options...
