Hi guys,

With Winter now here I could really do with the old girl blowing hot!

Switch works fine and blows cold air in both directions, but the hot/cold lever on the side of the dash is stuck on cold. Had a look under the bonnet and there is a cable just hanging there, looks like it's rusted through and is probably the hot air cable.

Where would this cable come from? when I get a new cable where would it go to after I get it in the dash?

Any help very welcome.

Thanks in advance

The cable should go to the heater valve which is on top of the engine at the front,you can just move the lever on the valve to hot with your hand if your a tight git like me

Yes u can just move the valve by hand but hope u arnt expecting much heat mid

round thingy attached to coolant pipes at the front of the engine. turn little pokey outy bit clockwise for cold, anti clockwise for slightly less cold.
i keep mine in position with a spring hoping that extra 1mm the spring makes adds more warmth, i think it may do as the windscreen now only takes 17miles to clear.

Cheers guys, I'll take a look later. Any warmth is welcome.

If that doesn't help try backflushing the heater matrix with a hosepipe.

I don't seem to have a heater valve on the front of the engine or any lever that I could turn. Any diagrams/links to hand??

Ebbingeii · Nov 19, 2011

Has one of these heater control valves I've now found!! Must have replaced the one you guys were describing. Do I just turn this anti-clockwise for some heat, or is that a stupid thing to do?!?

What you want is this
WATER VALVE FOR SERIES 3 HEATER - 90577299 - Land Rover Parts & Range Rover Parts
the cable is operated by one of the levers to the right of the dash which operates the lever on the valve. I found a bit of ptfe tape on the threads helped.

I'm sure I read somewhere that the series 2 one was a manual tap under the bonnet, may well be wrong though

Yes, all the way.

No

Also good idea to disconnect both feed & return pipes from the heater & back flush through with hose pipe.

Ebbingeii · Nov 20, 2011

I'll go and turn the cog anti-clockwise now and go for a cruise, if that's possible in a dranner, and see what happens!

Ebbingeii · Nov 21, 2011

Seems to have worked! Not exactly HOT but luke warm.

Thanks for the help

oxides · Nov 21, 2011

Now for that backflush.....

schmalex · Nov 22, 2011

I just hold my heater control valve open with a zip tie, as the cable is rusted through. Never had any issues with doing this whatsoever & get reasonable heat into the cabin (after a while!)

Thekeymaster is right series 2 and 2a have said tap on top of the cylinderhead near the bulkhead.Works just like any other water tap.
