Hi Will,
I just came across your post from November - regarding the diagnosis, the clutch is just a 12v solenoid effectively, so rig up a positive wire with something like a 15A fuse in it and connect that to the single wire (from memory it earthed via the block) going into the compressor. That will tell you if it is activating - a healthy click. If it does, try then loosening the belt and turning the compressor by hand.
I had an old Cadillac that the compressor had seized on, so the previous owner had just cut the wire and pulled the fuse. If it is seized and you get the clutch to pull in you are at risk of trashing your drive belt.
Anyway, interesting that you say your car is 95, as the A/C you have fitted is the aftermarket unit from Pre 1990 ish. From 94 onwards all Japan car had factory fitted A/C with 134A done at Longbridge.
The 1st car I saw like yours was the kit made by Unicla of Nagoya, Japan. Later, the front mounted condenser that you have was moved to the RH inner wing but was still a Japan fit modification. Then we had the fan cowl welded in during production. I suppose there is a chance a 95 car was shipped out and retro fitted, but it would be a strange thing to do.
As for the R12 and the seals, I also have a recollection that both the seals and the Oil in the compressor were unique to R12 and not compatible with 134a,
Hope some of that helps
Chris
Hi Chris,
I have only just seen your reply sorry! I can confirm the clutch does engage when I apply 12v to it. I have not checked the compressor spins freely - so thanks for the heads up. I'll be sure to check that.
It is a bit of an odd car. It was UK built and sold, then apparently sent to Japan, so not strictly a Japanese spec car.
As for the seals and oil, I intend to leave it to a professional - hopefully in the next couple of months.
Cheers,
Will.
