highlandmist Posted June 21, 2012 Share Posted June 21, 2012 Now, I usually have the heater control at 2 because nothing much comes out if I don't. On a coule of occasions, when moving the control up and down I did get a decent flow of air but it's usually mediocre. I'm going to have to start fault finding now so that I can get it sorted for winter. I wonder is it likely to be an electrical thing with the control itself and how can I test this theory ?

western Posted June 21, 2012 Share Posted June 21, 2012 might need the slide contacts cleaning or it might be just worn out. Quote Link to comment Share on other sites More sharing options...
mcc1979ian Posted June 21, 2012 Share Posted June 21, 2012 i saw something on ebay a couple of weeks back for the defender heater that altered the fan speeds so as to give better flow in the lower speeds, was £19.99, sure if you type landrover defender heater its one of the first things that come up. would post a link but i still havent figured out how to do it Quote Link to comment Share on other sites More sharing options...
Ex Member Posted June 22, 2012 Share Posted June 22, 2012 IME, it is usually the fan has mud in it and does not spin well at low speed. Take the grill off and look inside. A wash with a hose is a good idea. Quote Link to comment Share on other sites More sharing options...

Sirocco Posted June 22, 2012 Share Posted June 22, 2012 I think its just the resistor. If you find it only works on full it may be broke. G Quote Link to comment Share on other sites More sharing options...
highlandmist Posted June 22, 2012 Author Share Posted June 22, 2012 Okey dokey, I'll check the fan first, then maybe 'shine up' the contacts before considering the upgrade kit. Quote Link to comment Share on other sites More sharing options...
Tanuki Posted June 22, 2012 Share Posted June 22, 2012 Before changing any parts, check that the intake-plenum thing on the passenger side wing isn't full of leaves/nutshells [yes, I've seen this in a Defender that had infrequent use: seems the local mice were holding nightly nut-parties in there !]. Also make sure the levers are actually operating the air-flaps: if they seize then the control-levers may still go up and down but the outers of the bowden-cables can be just sliding in their mountings and not doing anything helpful to allow the air through. --Tanuki.

highlandmist Posted June 25, 2012 Author Share Posted June 25, 2012 Had a look today. The intake and fan are lovely and clean. Slider and contacts were full of what looked like spray on grease !! Cleaned it all out an it seemed to work. Put it back together and it wasn't working again. Took it apart once more and found that if I slid it right down and then touched the contact on the slider with a screwdriver the fan came on, any movement would put it off again, so I'm guessing the slider unit and contacts are kaput ! Now, to google for the part number.... Quote Link to comment Share on other sites More sharing options...
western Posted June 25, 2012 Share Posted June 25, 2012 no need to google, it's item A 4th from top of list part number UTP1125 in this diagram http://www.numcat.ru/landrover/p/31/52983/ http://www.lrseries.com/shop/product/listing/15623/29/10/UTP1125-HEATER-CONTROL-ASSEMBLY-LHD.html Quote Link to comment Share on other sites More sharing options...

I already ordered part STC4848 before reading your post !! I have done a search on the part you listed and it seems to be the LHD version. I hope I got it right Quote Link to comment Share on other sites More sharing options...
western Posted June 27, 2012 Share Posted June 27, 2012 it fits on the left hand side of the instrument pack, it used to be UTP1126 now STC4848, apologies for the incorrect number, wasn't aware there were LHD & RHD versions. Quote Link to comment Share on other sites More sharing options...

Orgasmic Farmer Posted June 28, 2012 Share Posted June 28, 2012 New resistor (courtesy of SimonB) fitted now. Bish, Bash Bosh, 2 screws, 3 wires and job done. Works perfect. Got 2 speeds back and all is well with the world. Quote Link to comment Share on other sites More sharing options...
highlandmist Posted July 1, 2012 Author Share Posted July 1, 2012 New one fitted and working nicely now, apart from the mediocre low setting. May ask for a forum discounted solenoid when the frosty weather starts again Quote Link to comment Share on other sites More sharing options...
