Hi Kevin@sovlimos

I assume you are talking about the A/C compressor and if that was glowing red you are not going to be able to repair it, just stump up the 290 for a new/reman unit make sure it is not a Four Seasons brand one as they are crap.

You are also going to need a suction accumulator/Drier, an orifice tube and the system flushed.

As for pressure in the system you will have about 60/65 psi at 70 degrees falling to less than 40 psi at 40 degrees, if you crack the pipes off (not the correct way to do it and probably illegal) all you will get is a brief hiss as the refrigerent vents.

Regards

air con unit

Hi Dereck,

many thanks for your quick response, pulled me out the s.... again. So do i have to get a mobile air con guy to depressure the system first for safety. i will order a new one in the morning being quoted 225 plus vat and delivery 284 DOH. And its going to cost me to have it pressed again is that right.

Thanks Again
Great help

Hi Kevin@sovlimos

You really need the suction acumulator and the orifice tube as when you get a spectatular compressor failure it fills the system with metal filings and goo, it would be bad economics not to fit them.

From memory the orifice tube is about 12 and the accumulator about 90.

Regards

I've had several clutch units fail. You can unbolt and replace the clutch/pulley without touching the A/C stuff. Of course the clutch could have failed because the compressor seized. If that's the case, you need a new compressor.

A/C compressor

I have replace the ac compressor with a new one, how ever when i put the air con on its blows a fuse under the dash, i dont think this was the case with the old one, when the air con guy fitted it he mentioned he was not happy with the centre bolt of the compresser he said its solid, he did mange to make it turn eventually, could it be that thats blowing my fuse, i have swopped over the big square fuse under the bonnet . Its runs on ac for about 5 seconds then pops the fuse.

You have a short somewhere. Could be a bad clutch diode.
