Re: How's the charge looking on this custom system?

JohnHere, Thank you for your reply.. Just got back from my trip and will be working more on this shortly. Would love to have a simple "old Fashioned" way to do it and have a couple questions on what you wrote. Will ask those once I can phrase them clearly. First I have to re-evacuate my s...

Re: Getting power to the relay but nothing to the compressor

I don't remember anymore, but did you replace the pressure sensor on the evaporator tube? It should have a Schrader valve behind it, eliminating the need to recover the system beforehand.

Re: Gs300 new ac components but immediately shuts off

So the only way I can flush the evaporator (behind the dash) is flushing through the lines that are connected to the condensor and compressor. I just disconnect those and cycle through the lines, evaporator and expansion valve. If I remove the expansion valve it would allow the flush material to ge...

Re: 2010 honda civic ac not blowing cold

The A/C system does not have the correct amount of refrigerant in it. Just an ounce or two either way in such a small-capacity system will cause problems. At this point, we don't know precisely how much refrigerant the system contains...and the amount MUST be precise.

Re: Fan Speed?

Have feeling my one canister of 12a refridgerant wasn't quite enough to hold near the top of the blue good range on my cheap guage. If you're in the United States, why not just use R-134a, which is what your car was originally designed for? Although R-12a reportedly is compatible with the former, i...

Re: 98 Buick Park Ave AC troubles - Hi side won't build

I think you inadvertently over-filled the system with oil if the Denso compressor and the junkyard compressor came with all 9 ounces in them. It's very difficult to correct that now, though, because everything you do would be guesswork. How much oil do you remove? Who knows? I responded to another q...

Re: Gs300 new ac components but immediately shuts off

For some reason I thought the AC compressor came with only enough oil for the unit itself but that would make sense if it has 7oz like you stated. That might be where you went wrong. Some compressors come filled with enough oil for the entire system, and some come dry. What would be the best approa...

Re: Getting power to the relay but nothing to the compressor

ok yeah, I thought about that as well, but when jumping it there is no problem to jump the power. I even tried taking the fuse block off to get to the wiring connectors but it was getting a little tricky so I stopped. However, as I said, the terminals jump no problem. Who said that troubleshooting ...

Re: Getting power to the relay but nothing to the compressor

When I jump the relay the compressor kicks on so the wiring should be fine between the relay and clutch. But I checked anyway for continuity on the wire between the relay terminal that feeds the compressor clutch and it read 1.4 ohms. Then something has to be amiss in the area of the relay...maybe ...

Re: 98 Buick Park Ave AC troubles - Hi side won't build

Bringing an end to this thread... The problem is solved. I didn't understand the VD compressor concept previously, and upon following your recommendations, everything seems to be working upon my most recent recharge. I also did not realize the length of time this process takes. In all, it probably ...
