    Range Rover Mark III / L322
    I have a curious problem on my 2003 Range Rover. At driving speeds of below 55 mph the heater works fine, blower all speeds, air con..... When the driving speed exceeds 60 mph, the heat from the blower disappears (fan still functions). When I slow down to below 55, the heat comes back. Has...
  3. Unique Heater Issue - 2006 HSE

    Range Rover Mark III / L322
    It's not like I haven't had my share of issues with my newly acquired RR HSE, but here's my latest issue. First off, for the last few months the heater and AC have worked flawlessly. So good I actually have expressed my happiness with the system. The other morning I was driving home and wanted...
  4. '93 Classic Heater controls frozen

    Range Rover Classic
    My heater controls used to operate normally, maybe a little stiff, but I could always move them and hear a "clunk" when the internal baffles moved into position. Now, after a season or more of dis-use, the left up/down control lever and the right up/down lever (the one with the foot-icon at the...
  5. 2007 HSE Blower motor not working

    Range Rover Sport / L320
    Ok, I have dug around on this site, others, and googled my brains out - behaviour is indicative of FSR failure based on my research. The 40amp fuse was blown, replaced it and it all worked fine, for a couple days. Shop says no codes showing, so see if the fuse fixes it (thought this was somewhat...

  7. Heater fan working on 1 and 4, not 2 and 3

    Range Rover Classic
    I've just had the blower fan out (soft dash 94) as it was squeaking (found a wet and dry pad in it!) but now its back in it only seems to spin at spped 1 for 1, 2 and 3 and properly again at 4. I wondered about the resistor pack but as it does work on speed 1 is that the only option? I can't be...
  8. Heater control unit

    Range Rover Mark II / P38
    Hello all, The heater controls work fine on my 97 P38 4.6 HSE apart from the fan control knob, for some reason to get it to increase/decrease speed I have to spin it around and around numerous times before it registers different speeds. It is a small issue but rather annoying sometimes. Is there...

    Hi Just done the head gaskets and cam in my 3.5 v8. Can't remember which way round the heater hoses attach to the manifold? Are upper heater feeds normally engine outlet and the bottom a return or other way around? Thanks.
  11. air intake noise, heater problem

    Range Rover Sport / L320
    Hi all. I'm having these problems with my RRS 2.7 HSE. Your suggestions and help will be very much appreciated. Excessive noise comes from the under the bonnet when I press the accelerator, sounds like a fan motor turning really fast trying to pump air into the engine. Hardly any hot air comes...
  12. Tips on replacing the water heater hose adaptor

    Range Rover Mark III / L322
    I discovered a coolant leak that turned out to be the water heater hose adaptor. I ordered another this morning and would like to install it ASAP. I have read others that say it is an awkward but not difficult job. Once I have removed the cabin filter shroud and gain access to the rear of the...
  13. Heater Core flush

    Range Rover Sport / L320
    Hello, I am having problems with little to no heat on the drivers side while the passengers side heats up nicely. After doing some research it seems the heater core is the likely culprit. I am going to try flushing it out to see if that will make any improvements. Does anyone have any tips on...
  14. heater motor

    Range Rover Classic
    On an 1989 range rover, the heater motor is attached to the rest of the heater-core-box by a handful of screws. It appears that if the dash was removed from the truck, one could easily replace the motor without the need to remove the entire unit. That doesn't appear to be the case on a 1990...

  16. Heater Problems (not blowing hot)

    Range Rover Mark II / P38
    Hi Guy's, Ive got problems where my heaters only seem to blow warm.. I was told that it could be the blend motor, but I'm not convinced as yes, the left hand blend motor does throw a fault up but why don't I get heat out of the right side? Ive plugged my nanocom in and read the live data...
  17. Heater core replacement Right Hand Drive

    Range Rover Mark II / P38
    I recently noticed a few drops of green antifreeze seeping down the end seam of the heater core and decided to do a bit of preventative maintenance by replacing the two 'o' rings before the problem got worse. I used viton 22mm x 2.5mm 'o' rings and after searching on this forum for the technique...
  18. P38 heater problems

    Range Rover Mark II / P38
    Hi guys, My p38 heater blows warm but not as hot as I would have expected. At first, I thought it was the thermostat sticking until I plugged my nanocom and read the data and it shows that the heater core is showing the same temperature as the cooling system. Any help would be appreciated Ash

  20. Backlight of Heater Control Unit - Bulb replacement?

    Range Rover Mark III / L322
    G'day, I'm new to Range Rovers as well as to this forum- after recently purchasing a 2006 L322 - and could not find any information on whether the temp degree scale of the two temperature control knobs are backlit. Why am I asking....when dark, one can hardly see the temp setting. Watching...
