Poor "AC" on the V8 powered cars!

Poor AC on the V8 powered cars!

I’ve had this car just over a month and its been looked at 3 times for its AC. The problem is that there is nothing wrong with the AC according to MG.

WRONG there is, it just doesn’t work effectively. Consequently the design must be wanting in some way - see bottom of post!

Last night for example we drove 6 miles and the screens barely cleared with HI selected on the AC interface. This isn’t right, plus the noise at this level is unbearable. Or is my expectations after the previous cars fitted with AC too high?

To be very frank – I’m disappointed and this niggle is starting to annoy.

I have to say I always drive with the AC on and this is spoiling the enjoyment of the 260.

AC info, A new HEVAC (Heating, Ventilation and Air conditioning) unit is fitted to the ZT 260. The new unit is a water-blend design featuring a dedicated electronic control unit to drive servo-motor valves to regulate the water flow around the heating circuit. This system has been refined to offer similar levels of response and control to the existing ZT’s acclaimed air-blending system. All models feature ATC (Automatic Temperature Control), using the familiar user-friendly interface of other ZT models.

I got my ZT260 SE (#85) end of Feb 04 (lookers Stockport), I didn't appear to have a problem with the A/C heater, probably due to the weather. During the summer Though when its not been warm enough for A/C, I've had it switched off the vents leaked major ammounts of hot air both dash and footwell. Its had the new valve, no difference, had the flaps reset, no difference, infact if the A/C is off and the sunroof is on tilt it draws hot air from some where just as if the heater is on full blast. As with most of you for me its spoilling my first ever new car and a car that is otherwise fanbl**dytastic. Got the xpower exhaust on order. If any one is interested in power parts for this engine (I'm into American motors big time) check out Summit racing ( cant remember full address, will look it up and post it) if its made for a 4.6 modular motor they stock it. There are also various mags that deal specifically with the Mustang and tuning them. The mags are availiable from American Auto mags in Winsford ,Cheshire, Graham Rennie is the guy to speak to he has plenty of mags in stock :roll: :lol: :beerchug I'll put the details up again as a new topic tomorrow so every one can see them.
