Fender heater performance

[Graz]

As a relative newcomer to the Fender camp I noted that the heater doesn't exactly burn my knees, in fact it bearly heats at all.
Is this to be expected or can something be done to improve it?

I know its getting to be a non issue but winter will come around soon enough.

Heater, what heater? I did not know they had one.
;)
I would have to say with my 110, that is one of the things that does work well and gets real hot real quick.

Heater what heater is exactly right!!

Mines never worked and i figure with all the places the warm air has to escape there aint no point fixing it.

Its on the end of a very long to do list!

[hiline]

my one works really well as well :D

its so hot you cant hold your fingers over the screen vents for to long it burns you almost:p

Mine's always worked quite well. It's the fan that is cactus, and I saw it is very expensive to replace (and not easy coz you have to get behind the aircon unit or something) so it's staying cactus until I win lotto.

I'm in WA so it is not super necessary to have the fan, though to demist the windscreen it would be handy, and I hate having stuff not working.

have you thought about retro fitting a cheap 12v hairdryer in place of the fan.......?

or maybe one or two of the little fans you find in computers.......just to get enough airflow to get some heat happening......

Does the heater fan work?
So does it not blow any air out the vents or does it blow slightly warm air?

Yes my Tdi fender heater works realy well im happy with mine:D

It seems that this is one of the weaknesses of the Defender. The heater in my 110 is certainly nothing to get excited about, but does work to some extent.

What I have found over the years though, is that it is very sensitive to the thermostat working properly - a thermostat that is not keeping the engine temperature up makes the heater useless. I have fitted three thermostats over the years.

I have not pulled my actual heater apart (one of those jobs on the to do list), but a potential source of trouble is the seals on the flaps in it - since it depends on changing airflow to change temperature, faulty seals that prevent the cold air from being shut right off will stop it working, as will a sticking cable or maladjustment that is stopping the flap from moving its full travel. Also, there is the possibility that there is air getting past the heater radiator without going through it.

A further possible source of trouble is an airlock preventing coolant circulation.

My heater is brilliant! Gets the rig to hot. It's getting cold air from those vents that's hard.

Yes the fan works. The air is only slightly warm.

Thanks for the replys. I'll try doing what has been suggested. It seems it should be performing better than it is

Alrighty.

Man from the cold end of the earth here.....

The heaters are perfectly fine....if in good running order. Although they are a little small for a 110 CSW in the arctic.

1) Adjust the cables. 90% of the time this is the problem. The hot/cold cable does not close the door fully.

2) Open up the vents. They are somehwat restrictive.

3) Make sure your thermostat is working properly.

4) Make sure your heater matrix is not fouled or plugged.

Just another day in the 90

Graz,
One other thing to check on your vehicle is the drain valve under the heater inlet on the passenger side wing.

This is 'designed' to allow any water / dust etc to drain away from the air inlet into the heater box.

I found that mine was completely blocked by mud/ gumnuts filth etc, and the inlet assembly was full of water, which tended to impair the heater ops somewhat - whenever the heater was selected to demist, the inside of the windscreen would mist up with condensation.

A quick attack with the airline soon cleared it out, and the heater was much better. I know that this is probably not your main issue, the cables sound like the main problem, but maybe worth checking all the same.

Cheers,

Mike.

Thanks for the advice, Zook. Food for thought.
