Does anyone know how cold air con should be? When I hold a thermometer in
front of the vent on my Disco it reads 14deg. When I do the same on my wifes
Mondeo it reads 4deg. Both cars the same conditions, ie. fan speed high, all
vents shut apart from one centre dash vent. Checked after 3 mins at idle
speed.
Thanks in advance

Not specifically Disco but as a general rule any aircon should pull down
to less than 5 deg under those conditions - methinks the Disco AC is
getting tired.

Sounds like it needs re-gassing.

Had the air con checked on the Freeloader before a trip to spain. Dealer
said it measures 4 degrees C and that this is normal.

had air checked out today and they say the air con is working ok, re-gassed
it, pressure tested etc. and they seem to think the heater valve is passing
when shut so its trying to cool hot air. does that sound right ?

Sounds possible - unfortunately I can't help you with any Disco specifics.

Heard about that possibility before.Can easily be checked with AC
off,temperature all the way to the left,(cold) ,fan on,engine hot,and check
if the air that comes out of the heater almost has the same temp as the
outside temp.
On the freelander forum is a thread that explains how to readjust the cables
to ensure there's no hot water going to the heater.

if the heater is similar to the normal disco heater, then it circulates hot
water all the time and switches the air flow instead. still relevant about
adjusting cables, just what the cable does is different.

dont know what you mean by 'normal disco'. ours is a 3.9 and they have a
vacuum operated water valve which is controlled by two micro switches off of
each heater control (one for passenger, one for driver). when both controls
are in the 'cold' position the valve is shut and hot water bypasses the
heater and recirculates back to the engine instead. when either controls are
moved from 'cold' a microswitch operates and the solenoid opens the water
valve to the heater then the air flow is controlled by either control knob.
amazing what you learn by reading the manual.

" and the solenoid opens the water" by which i mean the solenoid operates to
allow the vacuum to open the water
valve

ooer. I've never actually read that bit. I assumed it was done with the
sort of heater that vents air either through or round the matrix.

dont know if 3.5's are the same. I think the later 4.0 are differant. I
might try and change mine to another system as the hot water v/v is passing
and tried two more and they were the same.

New pattern parts control valves shouldn't be very expensive - I expect
they are the same as Jaguar ones which are the same as half the 70's and
80's American cars. The last one I bought for a Jag was only in the
region of GBP10 and is still working perfectly on a customer's Jag
(after 12 months).
