Thread: No Heater

what youll prob find is its a problem with the heater blower motor, and there is one fan for the ac and one for the heater.

it could be a faulty switch, relay, fuse, resistor pack, or motor.

for me in my older d1 (92) it was a siezed motor.

good luck, grab a multimeter and wrokshop manual and start tracing the volts...

Hi Haydent is the blower the same as the fan control because the fan works fine just blows cold air.

Both sides? One side? Is there any air blowing?

The car has two blowers, one for each side. It's unlikely both would fail. What happens when you use the temp control buttons to go from min to max on each side? Do both change? Neither? Only one side? If so, perhaps it's the blend motor(s).

My first guess would be a blend motor. Read the diagnosis pages and repair pages on RANGEROVERS.NET HOME e.g., Blend Motor Diagnosis and Replacement

sounds like a problem with your mixer if your fan works with the heater settings on

Thanks Guys the temp display works fine both sides up and down the fan works fine, when auto is on the fan switchs to all vents, you can turn the air on and off all direction buttons work if you switch to face vents and put your hand on the center you can feel a small amout of warmth out of drives side but dead cold out of pasenger side nomatter what fan setting you have it on.

When you adjust the driver's side temp up and down, does the temp of the air change? That's why I asked you to go from max to min.

If so, you have a faulty blend flap servo motor on the passenger side. Quite common.

Read the diagnostic procedure in the link I gave you for RangeRovers.net

No the temp of the air dosent change at all, display temp go's up and down fine.
