Heater/AC issue - no air from dashboard vents.

Good evening all,
I'm trying to get to the bottom of a problem I've just noticed with my AC. No matter what settings I use the air no longer comes from the dash vents. I'm getting air in the driver footwell and the rear vents are fine.

Could this be the FSR or is it more likely to be a bad fan or a seized distribution motor? Ideally I'd like to repair this myself but it looks quite involved getting to the fans.

Appreciate any advice.
Thanks
Dan

Have you tried a battery disconnect / reconnect? I'm assuming you have no access to diagnostics due to the lack of posted DTC's?

Hi Phoenix,
Correct, I don't have any diagnostics unfortunately. Is a battery disconnect worth a try then? Both terminals off for a specific amount of time or just off and on again?

Thank you.

Yep, it's worth a try - key out for 3 mins, disconnect -ve terminal for 3 mins, reconnect. Pretty generic instructions but I've never had any problems with that sequence on any vehicles of this century.
Basically a disconnect / reconnect will force an end-to-end registration of all LIN devices in the air distribution path.

Hi Phoenix,
Thanks for this - I did the disconnect this morning and turned the car on and all was back to normal. Unfortunately, I had a run to the shop and when I got back in the car the issue had returned.

Worth trying it again?

edit: trying again hasn't made any difference. Bad times!

Cheers!

I'd get your battery tested, sounds like the voltage could be dropping quite low on cranking.

If you have a charger, try charging it overnight then disconnect / reconnect and see how it goes.

Thanks, I'll see if I can borrow a battery charger from somewhere and take it out and charge it off the car. I'll let you know how I get on!

Has anything changed? I had the same and it was after I’d been messing around with the panel and one cable was disconnected plugged it in and hey presto Current stable:

Any idea of the plug. I’m borrowing a charger but I can’t get it for a couple of days. I’ve got my fingers crossed though.

Afaik when you pull the top half out it went in underneath facing up instead of the rest which just plug into the back. Ultimately though check they are all in tight and non are missing Current stable:

I took the car on a run and the vents started to work. I've checked the battery with a multimeter and it reads 11.97 so it is low. I'm borrowing a charger today and I'll take it off and leave it to charge overnight. It does seem like it could be voltage related though as they fired straight up after driving for a bit.

If the battery doesn't charge properly and I need a new one is there a specific one that's recommended - this one is only a couple of years old, an AGM from Halfords.

Thanks for all the help, I'll be over the moon if it's just a battery I need!

If it’s not that it still could the that plug loose - is easy to check pull the cheek panels off leave the screws in and then just pull the module out a bit Current stable:

I've had a chance to charge the battery which seems fine but still having the problem intermittently (more often than not).

Dan, do you mean the footwell panel that you remove to replace the FSR? Then just check the connections in the back of the control unit?

Thanks again.

Dan

Yea passenger and passenger pull the piano black wood trims out word towards the door then you can easily get the module out by pulling it forward - I think you can pull it without getting these out but this gives you a bit more access for 40seconds extra work Current stable:
