I'm having an issue with heat on our 2000 Land Rover Discovery II. I check and flushed the heater core there was not blackage or leaking. One of the hoses entering the heater core is hot the return is not. Could anyone tell me if there is a heater control valve and if so could you give the locations. Thanks!!

My late mother worked at the Land Rover plant in Solihull and put careful miles on a Disco when it was known as the 'J Car'. Also the first Vogue with a turbo. Long time ago!
Hi welcome main problems are the abs valves causing the 3 dash lights (search 3 amigos online) a really badly sited compressor can cause air suspension models to fail giving the bags a slow leak the V8 is a solid engine but can have radiator expansion tank and cap failures
the other issue is electrics windows and door looms are problematic
There are two, one pre-cat, one post-cat! Both need a 22mm crowsfoot spanner, and care must be taken as they are easily damaged by dropping, excessive heat or contamination.
there is a valve in one of your heater core lines in the engine bay that controls the flow of the hot engine coolant to the heater core and is controlled by the hot/cold selector on your dash by a cable. have someone watch the valve while you move the selector back and forth from hot to cold and make sure it's moving the arm on the valve.
Please check the a/c compressor clutch; it may be not working. FYI the compressor does not run all the time. It is the clutch that will cycle on and off to maintain a/c circuit pressure. To check, put the a/c on high and watch the compressor under the hood to see if it cycles.
It sits behind the dash, and is a real pain to replace. It's a dash-out job I'm afraid, along with removing the radio, steering wheel, centre console and nacelle.
The code P1451 on a Land Rover is "Leakage Detection Module Motor power stage error Drive cycle A:Signal out
of range - above maximum". This is an OBD-II diagnostic system code. As far as I know, a 1995 Land Rover Discovery does not use a OBD-II system. Is it possible that this rover is a later model year
