Land rover discovery ii 2002 heater not blowing hot air and overheating

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

What blows cold air? The heater? Sounds like a radiator problem. I'd have someone flush the cooling system if it has not already been done. Could also be a bad or going bad Coolant pump, unless it has been replaced. It might be smart to do both at the same time. If the coolant pump is bad, it could explain no circulation of hot coolant through your heater coil.

dear,,,you need to change air baloon, it might leaking.

You can't unless you have the VIN of the vehicle it came from.

when engien is cold ,top up coolant bottle with antifreeze and see what happens ,or the heater hoses are on in reverse

Check your coolant level. Does it overheat at all?

Hope this helps (remember rated this).

have you checked your coolant? that might be why its blowing cold air

check ur thermostat its not opening to let heat pass through

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.
