Hi all
I have an issue with heater for quite a while now. The blowers work fine but it takes a long time for it to blow some warm air (nearly 30mins). I have noticed that the temperature gauge on dash has to be in the middle to get warm air. Nowadays the temperature gauge goes down as I use the blower therefore blowing cool air. I am guessing it is something to do with the temperature sensor.

From what I understand is, there is a coil which heats up (and motor for blowing air) and I am guessing the principle is like a household portable fan heater. If you turn the dial to RED the coil receives current and depending on the fan setting the amount of air flow is regulated. When turned to cold less current or no current passes through the coil and fan blows cool air.
What I dont understand is why does it interlink with temperature sensor of the vehicle (i.e. the one on dashboard). It should be just a rheostat which regulates the current flow to coil shouldnt it?

I have changed pollen filter before and the blower was blowing more air but it did not rectify the heating issue.

I have active 1.2cc 2003 3dr stilo.

Any help will be much appreciated

mine being a diesel I really struggle with the heater in winter time, I find it very poor especially to demist window.
as far as I know theres no electric element in the stilos its just engine coolant heat that is used for the heater. others will confirm or deny ?
if your petrol car is taking that long to warm up id be suspecting the thermostat ?
does it warm up quicker just idling parked up, a petrol should, where the diesels don't really.

unless I am mistaken, there will be a heater matrix that the pipe work lead through, and as Sussexa says, probably your thermostat is at fault and that would be my first check. Temp sensor wont regulate the temp, if it was faulty it would just read cold all the time, so check the thermostat - not sure how easy / hard that is on a 1.2 though but on the 1.9 diesel its a bit of a pain..

An electric PTC heater was available for the diesel Stilos. Not sure if it was an optional extra, but it wasn't fitted to all diesels.

Perhaps it was part of the "Cold Weather Pack", along with headlamp washers, heated seats and heated windscreen washer jets.

like to get to the bottom of this.
on your info looked into fuse section of manual and have found listed
additional heater(multijet versions) f73(midi fuse) 50amps figure 61 shows its the battery pos terminal fuse box and is the one next to the 150amp maxi fuse for the ecu(f70)
wonder if it is activated via heating knob and fan speed and needs aircon compressor running?(manual climate control) this is all the manual says to get fast defrosting or demisting and I don't usually have aircon on(and also usually have heat knob on cool to speed up engine warming)
if I havnt got it id like to retro fit it if possible, any more info like part number or wattage ?

edit
just been out to have a look for that fuse and ive got nothing there just an empty space and no wire to it ,
so to retro fit would require fuse , wiring , activation button/circuit, control circuit, relay and heater matrix , if theres even space for it in a standard unit (unless it could slot in where the polon filter sits)
found this too much for me to be bothered with it might help others who consider it

Hi all.
Thank you all for responding. It looks quite complicated. So I will try not to attempt it myself. Incase if I decide to do it I will keep you all posted.
Thanks once again.
