110 with problem aircon

TIL110 · Jul 18, 2017

Hi everyone, (originally posted in the wrong section)

I've something puzzling me....I've recently acquired a 58 plate 110 double cab with Air Con.

The thing is....with the aircon switched off, and set on cold/blue, I get ambient air through the topvents and warm (not red hot) air through the foot well vents?

Shouldn't the air temp be the same whatever vent it comes out of??

With the aircon on...its cold from everywhere....with it set on hot/red, it will peel the skin off your face, again from every vent....but put it on cold/blue with the aircon off and the footwell ducts are hot!?!?

I don't want to be driving everywhere with the aircon on....so has anyone got any ideas, thoughts or experience of what it could be?

Cheers

I've got a slightly earlier model, but it sounds about right to me. The bog standard 'cold' setting is just the air from outside, having passed through some pipes in the car, so it does feel slightly warm as the engines chuck out a good deal of heat and warm up the bulkhead and dashboard area. If the air is genuinely cold with the air conditioning on and hot with the heater on, it sounds like things are working. You usually get a bit more noise when it is on too, as the compressor is engaged and the fans in the unit are spinning.

Ah those heady days of driving my old 1988 3.5 v8 110 having toasted feet in summer and icy in winter.

Aircon in a 110 with no front flaps to worry about rusting. Do you have tissue I have something in my eye.

Thanks very much for this...I'm going to put it through some tests and feedback...maybe I'm expecting too much

58 plate isnt a TD5! Tis a newer exotic beast to which I have very little knowledge! Though Defender A/C and heating are not great from standard, don't expect modern performance in that area!

Sounds about right to me. There is an exhaust cat (on mine and probably yours) behind the driver footwell and bracketed to the cog box, tends to warm up everything in the transmission tunnel / lower bulkhead areas, which will warm things up in the cab. Even in winter you will want the temperature setting on very low but you will appreciate the benefits of a landy that doesn't freeze your nuts off.

One thing that did improve my TD5 A/C a tad was wrapping all the A/C pipe work in pipe insulation and aluminium tape in areas. May be worth doing the same on yours.
