Afternoon guys.
One of my heater vents on the dash doesn't seem to blow as cold as the others when air on is on, it blows cool but not as the others, do theese have blend servo motors on like the p38 ? Or is something sticking somewhere
Cheers

Four blender motors (if you disregard the fifth which does the recirculation), on does the drivers side temperature, one does the passenger temperature, one switches the windscreen vent, and the last blends between the feet and face vents.
That's if I recall correctly and I'm right with what I'm saying.
Could your symptoms be caused by a failure of any of these would you say?
I seem to recall on an issue of Land Rover International the P38 does have servo motors as well.

My face vents don't work at all, either in auto mode or when manually directed. They're turned on but nothing comes out of them. The fan works fine and I can get hot or cooled air from the screen or feet vents but nowt from the face. Suggests that the face/feet servo is stuck?

Yup, I get the prof defrost light flashing everytime I get into the car. It takes about 30 seconds before anything happens, the light extinguishes and then I have control over the settings etc but still nothing from the face vents. If I leave the system on full auto and it's hot (as per last few days), dial the temp down to 18, the fan races and the blend motors behind the dash move about but still nothing from the face vents. I have to manually set it to screen/feet in order to get air flow.

Could be. PM me your email address and I'll send you the manual I made if you want.
