Another aircon post

[dancool27]

I have a issue if you can help.

Had my aircon recharged but only seem to get cold air on tickover.

Clutch engages on compressor and fan goes. Although revs don't drop much when turned on

Any ideas. Dan

Have a look at your pollen filter, mine was near enough made of leaves :-/

Does the clutch disengage when you raise the rpm?

Seems to be intermitant. Turned off for 15-20 min while driving when turned back on it worked but then after leaving car for 20 min next time it was started it didn't work. Maybe where it hasn't been used in a while

Still very rarely getting cold air. , been unable to check how fast clutch spins at moment if it does is it easy to change

under pollen fiter seems fine it blows out air with good force

I don't think it's the clutch. I suspect one of two causes...

1. There is is a blockage in the system (probably the drier).

2. The pressure sensor is faulty.

Whilst the compressor is spinning slowly you get some cold air. As it spins faster the high pressure switch opens the clutch circuit.
