Had my '08 Vogue for 2.5 years now. This winter I've been using the heater daily on cold morning and evening commutes, which is about 30mins. This week here in central Germany it's been generally 1 or 2 degrees above or below zero all day. I always let the engine get to normal running temperature before turning on the heating and I always just control it with the auto setting as that always works fine for me. I have left and right temp controls set to 20 degrees.

Previously I thought the the lights around the central blower switch came on an went off proportionally to the strength of the blower. Is this correct or do the lights indicate something else like approximate cabin temperature?

This week I noticed how the blower would come on strong after turning on the auto mode and the lights would illuminate accordingly (e.g. about 5 of 7 would light up initially). Soon after, however, the blower speed reduces again to a lower setting but the lights stay at 5 of 7, only going out at a much slower rate.

The car still seems to get nice and warm so I ask whether this indicates a problem or whether this just the auto mode doing what it thinks is best?

I have the face level vent temp control at half blue, half red but I've read it's better to leave at full red so I don't know if that may be the cause. Maybe it's just me and I haven't noticed this behaviour sooner. 2012 Vogue 4.4 TDV8 automatic (LHD), Santorini Black

Sounds normal to me, blows hard, lots of lights to start with (demisting etc.) then slows as cabin temperature settles, and less lights.

Mine decides its too warm after about 40 minutes though and starts blowing cool air, unless it is really cold outside  .

Hi there, i had a similar issue on my 2003 4.4 Vogue, the fan would start normally and then reduce then pulse etc.. the fan eventually stopped intermittently all together! Replaced the Final Stage resistor and it is 100% perfect now and toasty all the time!! part cost approx £35 and took a fiddly 30 minutes to change! If it keeps acting up this might solve the problem

Cheers
