My A/C didn't work at all when my G263 failed but maybe there was another problem after the G263 was replaced; I don't remember.

Morning Rab.
I had the G263 fault showing up very early on into Project OEMs ownership. Since having the system pressure tested and refilled with refrigerant it has provided ice cold air conditioning regardless of outside ambient temperature with the faulty G263 sensor.
The sensor was only swapped for a new one whilst I had the dashboard off over the 2021 festive period. I did try to change it before the dashboard removal as there are quite a few tips on the clubs pages on how to do it but my fingers had no chance of accessing the connector let alone removing and reinstalling the sensor.
Back to the OP @p1lyp, there has been plenty of information/suggestions provided regards this issue which is pointing towards having your system checked by an aircon specialist for leaks and faulty components.
Once this has been done then please do report back to let us know what was actually at fault as it’ll no doubt assist members later on when presented with similar conditions.
Kind regards,
Tom
I now have fully functioning air conditioning.
The first thing I did was replace the G263 sensor because I knew it was faulty and I had a new one to hand. This job wasn’t as bad as I was expecting. There was enough room for my largish hand but I couldn’t avoid it getting scraped. Refitting was the most tricky bit. You do have to extend your arm behind the pedals which is a little daunting. There is a guide on the forum which is very useful but it took me at least an hour, not 15 minutes.
There was originally no pressure at all in the system. I knew this from depressing one of the schrader valve pins. I had a closer visual check on the condenser and what I could see looked corroded and crumbly. I bought a Thermotec replacement from eBay (£68) which was an easy fit - taking the bumper off is a the most time-consuming part. I then took the car for a recharge. This was unsuccessful. The system held pressure but there was no cold air.
The last piece of the jigsaw was the compressor. I had bought a new one from ECP in the summer of 2022 (£118) and I fitted it over the weekend. This was the most difficult part of all because of limited access from the front. One of the three mounting bolts was really difficult to get to move - it had corroded with the compressor body. I also had a challenge getting the auxiliary belt off. The 16mm cast bolt for moving the tensioner had been rounded off historically so I had to remove the tensioner entirely and filed the head down to 15mm to re-tension the belt. I didn’t have a canted 15mm ring spanner but my neighbour did! Anyway, once the compressor was off, I found it was seized solid. There is a safety mechanism which allows the outer ring to rotate so If I’d looked at the compressor while the car was running I would have seen the problem before.
The was more corrosion that I was happy with around the hose seals. I had some fine wire wool and some new O rings and I was content after giving the areas a little TLC.
Took car for a recharge today - ATS £41.99 with Groupon voucher - and all is well. 9 degrees C at idle according to the mechanic and a lot colder at speed which I can vouch for.

I've been here, I know the pain, it's involved, I did the intercooler while was there and the tensioner and the belt and also the dryer accumulator ut that's harder than all of it. Well done sir good work as its hard dirty work that.
