Yes, mine has been in for over 3 weeks now. Got a crumby peugoet which goes no where and uses more fuel.

I've had no problem with my A/C. (still trying to get the oil leak in vacumn pump fixed though) Have you checked to make sure that the heater is turned off completely? I had the same problem in a GQ patrol and it was the heater not turning off

no i know what your saying solmanic as ours does it too

gets to a point then suddenly stops blowing ice cold air and just cold air you can feel them temp change

we too only have ours running on the first speed

Great, sounds like a repeat situation of the last model!! AAARRRGGGHHH!!!!Not happy Jan.

Probably Leaking hoses causing a lack of evaporator efficiency due to low gas charge/ pressure. Mine(RR) did the same thing before a loose hose connection was found and tightened, a re gas and 13months later still puuurfect. Just had the LSE done, new compressor fitted (after the old one 'caught fire' during the regas)and some hose work and it too is icy cold. Happy wife=happy life, as they say!

Just as a point of interest regarding to fan speed.

Assuming your air con is working properly - at low fan speed the air leaving the vents will be colder than at high fan speed.

This is due to the fact that the air is moving slower across the coil - and thus has more time to absorb more heat - plus of course it also removes more moisture from the air -

I would never recommend running on the lowest speed for long periods as if there ever is a fault due to a leak - evaporators can freeze - and split.

Freezing the coil - will reduce the air flow through the coil, and the air will 'go around' the coil and not be cooled, so you may be freezing the coil causing the lack of performance.

I would recommend that you get the gas charge checked - and if that is okay - just never run it on the low fan speed.

Sorry a little bit off thread, but still relevant (Just)

Check your handbook to see if the "Fix it first time" is still there. If so, do as I did once .... invoke the clause and have them collect the car and leave you the one they came in for your use...

Cheers

I have actually used that once before - got a nice Volvo S40 to drive around in for a week-end.

I am assuming that since they didn't even start to fix it, the clause doesn't apply ... yet. This turned out to be an exploratory inspection for them to determine if (a) it was in fact not working and (b) what the extent of the fix was.

When I collected the car they informed me that they had another one with the exact same problem that had just been in. Yes - it is over-cooling until it freezes. The detailed explaination was something like "there's a problem with the evaporator and it is sending the wrong signal to the ECU so it keeps cooling until it freezes rather than cutting out at about 7 degrees where it's supposed to" - or something - my eyes glazed over while he was explaining it.

No doubt they will rip out and replace the entire system - that's usually what they do

My 98 Defender did same, freezing first up then no good at all. The sensor was dislodged so the unit went flat out not knowing it was cooling, until it froze initially then after some time we could use it again and it would freeze (again). Sensor fixed and it has been good since.
