Great information; tight natural. Would read again.

Rebuilding my mom's 92 Civic. Trying to remove low side schrader valve to replace it. It unscrews & is loose, but it won't pull out? I've removed schrader valves on other cars before, but this is a 1st where it's loose, but doesn't remove.

Anyone know hoe to remove the schrader valves?

This is a great thread but I can't see any of the old pictures. Does anyone know if they are stored somewhere? Thanks

Ok I read the whole article (well, most of it) about how to charge the ac. Is it easy to take out the condenser and replace it? because I put a hole in it when I jammed the front end into it. I have pulled it out but I assume it stills has the hole in it because the freon discharged when it got punctured.

Does anyone have a wire pin out, wire color designations, or diagrams of the wires for the compressor of a 1992 civic? I've got two wires that run from under the pulley to the front of the compressor, and i have a single wire that doesn't have a clip, just a pin . Replacement compressors of the make and model suggest I'm missing a wire? Any help would be appreciated...the valves i have make me believe it had the previous owner had r134, but the system is evacuated

1 question, if you have time to answer. I told the mechanic to clean the IACV on my crv 2000. I suspect he did something to the aircon instead, because now it is not as cold as it used to be and also cools slower. He denies, of course.
in your opinion, what could be wrong? What do you think he might have done?
Thank you.

I was told that converting it takes a couple fittings and a hour labor, is this true?

Hi. My symptom is a little different and i'm hoping someone has an idea or two. I have a 2004 Honda Civic. My issue is that my AC cuts out (stops blowing cold air, for luke warm air) when it's in direct sunlight on hot (over 80 degree) days. It's very strange. If it's a hot day but over cast, the AC works without any issue. But when it's hot like when in direct sunlight, the AC comes on, blows for a bit, cuts out for a few minutes, then comes back on and repeats. The entire time the air is blowing on high, so there is no decrease air blowing into the car.

I have checked my oils several times over several months, and the pressure is the same. There is no leak. We also put a vacuum on it, but that didn't seem to solve the issue either. When the AC is blowing nicely, it really blows cold.

One blog i read suggested the issue was with the plastic electrical part that gives the AC it's power. I forget the part number. It has like 3 prongs on it, is plastic and is about $30. It suggested that inside this connector there is also a heat sensor of sorts and it helps tell my compressor when to turn on and off.

Anyhow... i'm at a loss. On hot but overcast days, the AC runs well. When in direct sun... it kicks in and runs great. Then all of a sudden it starts blowing warmer noticeable air for 2 or 3 minutes and then cold again, repeat.

Thanks for any advise.

Attempted to recharge the ac my 98 ex that I just picked up. Hooked up the recharge can to the low side then cut the engine and the ac on high. The pressure gage stayed at 0 and no refrigerant went in. Any ideas? I've check the 2 fuses under the hood. Don't know which one to check under the dash. Any help/advice will be much appreciated thanks in advance

The gauge should at least come up, it would seem that the can was not even tapped..

Those plastic recharge kits are absolute crap, you really need to spend a little coin on the proper tools or take it to a garage.

The first check on a car that won't engage the compressor is to see if there is any pressure in the lines, this is easy with the proper gauges. If you don't have those, unplug the pressure switch (on the receiver drier) and confirm it is closed circuit.

If the switch is closed, the reason the compressor is not running is not lack of charge.

If the switch is open, there is a big leak, and merely recharging is not going to get it working. Charge a little and use a leak detector (again, proper tools) to find the leak and make appropriate repairs. NEVER use a "leak stop" product.

It would be awesome to get the original pics back, but I think the OP has not been around since '12...

Theres no such thing as r32a or r132a, its r12 and r134a like he said. Some of you got your numbers all mixed up

NUBE: not sure how to post this: you guys seem like experts. Can I️ run my engine Belt V6 with no AC Clutch? It fell off. IE I don’t need AC

How is the AC compressor clutch activated when the low pressure switch is on?

iTrader: (2)

The pressure switch being closed allows the low-voltage "on signal" to be received by the ECU. Once received, the ECU then signals the 2 power relays to engauge the compressor and fan.

BTW: On the same circuit as the pressure switch, there are also several other switches that all have to be "closed" before the ECU receives the on-signal.
- AC button
- Blower Fan Switch
- Evaporator Thermostat
