hgray14 Posted September 27, 2009 Report Share Posted September 27, 2009 My '93 850 GLT isn't blowing cold air. I got a recharge kit and emptied a bottle (20oz or so) into the low pressure fitting and it still isn't blowing all that cold. Prior to starting the recharge the pressure gauge was running from 25-45, as the compressor (I assume) was kicking on and off about every 2-3 seconds. The pressure gauge never changed from 25-45 even after the entire bottle was put into the system. I was curious about the whole thing so I popped the hood on my '95 850 Turbo and got it running and the gauge stayed right at 40 without any movement of the needle. This particular car blows very cold all the time. What am I doing wrong? Does the compressor kicking on and off on my '93 mean it is bad? thanks Houston Link to comment Share on other sites More sharing options...

Kicking on and off means you haven't put enough it. Mine was going down to 15, and took 3 big bottles before it would be steady at 26 Link to comment Share on other sites More sharing options...
hgray14 Posted September 28, 2009 Author Report Share Posted September 28, 2009 Wow, no kidding? What is the capacity of these systems? So the kicking on and off thing signifies that it needs more? I know there is a gauge on there but once it stops kicking on and off that signifies that it is closer to full? thanks Houston Link to comment Share on other sites More sharing options...

But 1 can should bring you to a level where it doesn't cycle as often. Then... It should be added and measured based on the ambient temperature. IIRC @ 70F, you should have like 45lbs?... Don't take my word, this is from memory from the chart on the bottle I have at home (got it at pepboys). Link to comment Share on other sites More sharing options...
hgray14 Posted September 28, 2009 Author Report Share Posted September 28, 2009 Ya, you are right about the 45 but since the ambient temperature was very hot it was suppose to read somewhere around 55. (There was a conversion chart on my bottle for when the ambient temp is higher than 75 degrees.) It just kept jumping between 25 and 45 as the system kicked on and off. I put an entire 20oz bottle in and that didn't seem to change a thing. The air was no colder and the gauge never changed from 25-45. Link to comment Share on other sites More sharing options...
HayaCruza Posted September 28, 2009 Report Share Posted September 28, 2009 You could try a second can, after that if you still don't see anything I would say go talk to a shop. I added a little less than one can shortly after mine started to short cycle. If it has been a while maybe you could use a little more. Keep in mind, if this does work, it is just a band-aid you probably have a leak... Link to comment Share on other sites More sharing options...
KRUZNBY Posted September 28, 2009 Report Share Posted September 28, 2009 Try another can. You might be getting close. I recharged mine with one whole bottle when I first got the car. After about six months the compressor was cycling quickly, so I bought another bottle. I only had to add a few PSI and it was back to normal. My point is that it does not take much of a pressure drop to cycle the compressor quickly. Link to comment Share on other sites More sharing options...

I do understand that this is a bandaid but for the time being it will do the trick since we are heading into winter. Link to comment Share on other sites More sharing options...

Are you making sure to only add juice when the compressor is running (ie engaged)? Link to comment Share on other sites More sharing options...
