Thread: Passenger side air vents not blowing hot air

Hi

I'll be following this thread as I have just discovered this exact same problem with my D4 last week. Had not noticed it before as it wasn't winter :-)

x 3. Car going in to DazzaTD5 next week to see what magic he can do and hopefully get some brownie points back!

Is that why when my girlfriend gets into the passenger side of the car she always turns the vents downwards and says freezing?
Whoops lol!
Possibly x4!

How’d you go with those brownie points Gavin?? Please tell me you managed to get the whole jar filled mate and ya heater is working again (getting bloody cold down here)?

Nope. Car is back from service unfixed pending Dazza's preferred a/c auto elec getting an update from Rover after sparky doing initial diagnostics.

Apparently RAVE etc still show the D3 simpler semi manual system for blending etc, but there is an update for the D4 automated/computer controlled system which they didn't know about. I needed the car last weekend, so it will have to go back when I'm told the info required is to hand.

In the meantime a cold bride - but she rarely hops in apart from trips away as she has her own 10 year old C70 Volvo (retirement present to herself and which she loves).

I'll update as/when I get more info.

Had this issue, reverse flush of heater matrix fixed the issue.

Hi all

I had my Indy look at this problem with my D4 at my last service last week. They thought the small electric motor on the left side was not opening/closing the plenum flap thing that diverts air from the air conditioner to the heater radiator. That's the most common problem. Turns out that flap is apparently working fine. Computer says it opens and closes the flap and with a small camera poked down they can see it moving so it looks OK. They also twice flushed the radiator that does the heating, its behind the dash, and that was OK. They are stumped. It would now be a complete dash off with a full day just for getting it off and on again to find the problem.

So I have had no luck with mine either. My wife's Series IIa has a simpler air conditioning system that I can understand and diagnose if it breaks down :-)

Hi Guys,

follow the below link to the DISCO3UK forum and you will find that this issue is with the Heating Matrix. I was having the same issue and this was found to be the problem. Be aware, it is a big job, labour wise.
