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.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.

Looking back at my records, the G263 was replaced just before the condenser and dryer were also replaced, so the system wasn't working at the time of replacement.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.
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.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 alternator 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 retention 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.
