Air Con Fuses

[thb]

Would anyone know which are the fuses for the Air Con in a Tuscan 2 Covertible?

I've had the car for a month or so and the Air Con doesn't seem to be working at all. I know that the Air Con in TVRs isn't that good anyway, but I'm not getting any cold air at all.

I've checked the settings screen and it is turned 'On', so I'm guessing the next thing to check are the fuses. The only trouble is, there is no mention of Air Con in the fuse box diagram in the handbook.

Any help much appreciated.

Don’t think there are any fuses for the air-con as such, is the rest of the heating/vent system working ok? Can you hear a clunk when the air-con is switched on engine idle speed will also drop slightly (100 RPM)?

If not then it could be the Trinary switch is faulty or the system needs re-gassing.

I actually find the air-con works very well in my Tuscan.

The Heating and Fan seem to work ok, but there is no 'clunk' or drop in engine revs when the AC button is pressed.

The car is only a year/4000 miles old, so surely it can't need re-gassing already?

If there is no clunk or slight drop in idle speed then the air-con clutch is not engaging.

The Trinary switch monitors the air-con system pressure & if low or high pressure is detected the clutch will not engage. Maybe best to take it to the dealer & get them to check it out.

Thanks - that's very helpful

Nick,

I was also informed that the trinary switch was used to control the radiator fans (my drivers fan is currently permanently on! - and it's not the relay). Do you know where the trinary switch is by any chance?

Thanks, I get my car back from Offords tomorrow (or maybe Saturday) and they have replaced the trinary switch and regassed the system so I can get them to show me exactly where.
