superpoo93 Posted June 19, 2016 Share Posted June 19, 2016 Well first off, this is not my realm. Here we go.... I vacuumed system before recharging. Guages hooked to high and low after filling empty system with about 1/2-3/4 20oz can. Compressor will not kick, on. So jumped it... Turns on and can see bubbles in sight glass. Gauges at idle: Low: 52 High:50 Gauges When compressor engaged: Low:10 High:100 Rev to 2000rpm: Low: goes negative High:100 I read that low idle should be around 80 and 100 is too high, but when rev'd should drop to 40... Keep charging?? just need a little advise. Thank you Link to comment Share on other sites More sharing options...

Crazyeights Posted June 19, 2016 Share Posted June 19, 2016 It sounds to me like you might need to add more refrigerant. Link to comment Share on other sites More sharing options...
superpoo93 Posted June 19, 2016 Author Share Posted June 19, 2016 Yeah... I went ahead and added more. I stopped at. 90psi on the low side. No change. Compressor does not kick on. No bubbles in sight glass... Can swirling movement now. After letting system rest... And jumping the compressor. I do get a breif cool puff, then its goes hot again Static: Low: 90 High:90 Idle:16 High:130 2000 rpm: Low:0 High:140 Link to comment Share on other sites More sharing options...
superpoo93 Posted June 20, 2016 Author Share Posted June 20, 2016 You know when you get that feeling that maybe you shpuld stop... Doing what your doing. Yeah, I'm there. The low/high pressure lines are really hot. Well, I wanted to give a shot on my own for once. Think I just taking it in to a shop. Ill let you know what was wrong. Thanks Crazyeights for responding, I appreciate it. Link to comment Share on other sites More sharing options...
Loyale 2.7 Turbo Posted June 20, 2016 Share Posted June 20, 2016 ... I vacuumed system before recharging. ... Compressor will not kick, on. So jumped it... Was the Compressor working with its R12 gas, Before you attempting this R134a gas Retrofitting? Link to comment Share on other sites More sharing options...
superpoo93 Posted June 20, 2016 Author Share Posted June 20, 2016 Was the Compressor working with its R12 gas, Before you attempting this R134a gas Retrofitting? The R12 compressor was was working like a charm for a couple years after I bought the car. Then the compressor went bad. Had a shop work on it, and was converted 134A. Worked great for the first year... Then, crap! Same thing happened again to the new one. Oh, and the shop went out business :-/ Then I got the current compressor. Which works only when using jumper wire to engage. Thanks for responding Link to comment Share on other sites More sharing options...
Loyale 2.7 Turbo Posted June 21, 2016 Share Posted June 21, 2016 ... works only when using jumper wire to engage ... So, besides the lack of enough pressure (which I highly doubt in this case); you might consider a Fail on the Main A/C relay, behind the dashboard, and / or the two secondary A/C relays on the passengers' side strut tower, at the engine bay, as the Cause of this issue; because sadly, this fail is pretty Common on these EA82 / loyales.

Jesek, I dont think that I have never seen that write up. Wow, great detail. After work I looked through your post and started at the engine compartment relay's on the passenger side. Duh! Pulled the fuse and it was blown, replaced and compresor turns on now. Just need to figuire out why its blowing hot still. I finally found my shop manual. Going through it to determine what could be wrong. 1 Link to comment Share on other sites More sharing options...
DaveT Posted June 22, 2016 Share Posted June 22, 2016 Trying to think of what might cause both supply and return to get hot.... High side seems maybe low? I'm thinking the compressor is working, since the work is showing up as heat in the lines.The A/C section of a factory service manual has a LOT of detailed troubleshooting information.IF the condenser was not getting sufficient airflow, the system would be unable to cool properly.

l75eya Posted June 22, 2016 Share Posted June 22, 2016 Low side should be around 30-40 psi. High should be around 2-300. No more than 350 except for maybe a short peak as it cycles. Link to comment Share on other sites More sharing options...

Also I was considering to do a R134a conversion on my Subie, but the R12 is still available here, in Latin America. Please keep us updated; Kind Regards.

I was worried that R134a it would not cool as well. The R12 was amazin! Always had drive with my window cracked and on low/med... Brrrrr. The R134a does cool but not as quick, but does get damn cold. For example R12 would take a block or two to cool, R134 would take 2-3 blocks before you could roll the windows up. I dont know what it is at the A/C system in these cars but it rocks. Kids loved riding in my in summer..well when worked. Link to comment Share on other sites More sharing options...
