Air-Conditioning

[crazybiker]

Please, save me from insanity.

The air conditionier in my car, seems to LOVE to tease. It'll start and stop more times than a garbage truck will on it's routine run.

I can't figure it out.

The other day, I was coming back from riding, and it was a blistering hot day, so we thought to turn on the air conditioner, and it would just continiously turn on and off, on and off, and then it wouldn't turn back on at all.

Now, I know that it automatically dis-engages at WOT, but I was far from WOT, in fact, I would have been well and truly less than half-throttle.

from memory, it'd disengage at 3,000rpm, not throttle position...

also, is the condenser full of bugs/dirt and not cooling properly? quickest way to test would be to run air-con flat chat and have a garden hose on a constant fine spray in front of the condenser cooling it down. If your air-con gets frosty cold and doesn't cut out completely, you know where the problems at..

Also, if you drop into any aircon shop, i'm sure they'd have a quick look at it for you and at least point you in the right direction for no cost...

1. The 3000RPM theory may be right, but it definitely wasn't so in this case. I was cruising on the highway sitting on about 2100RPM.
2. The WOT theory is correct, aslong as GreenFoams resources are accurate.
3. It works well when it works. But it just cuts in and out.

[crazybiker]

Well, I guess that's no help then >_<

[Coast_Calais]

i think you misread what i said...

[justice4all3000]

possible re-gass??

[pow3rslave]

when i yanked mine out and also when i checked my fuses/relays a couple of the aircon wires had splits in the shielding, might be good to go over yours, and make sure your fuses/relays are all good. some fuses look ok but have bad connections or don't work at heat

[Coast_Calais]

i'll repeat myself if you want... your condenser can't keep up.
There's a really really simple way to check/prove this, then you can repair or replace it...

[crazybiker]

I'll try that thing with the condenser today if I get the chance.

[hi_ryder]

i had the same problem. i had my aircon gassed up in jan this year. then i had that problem where the trans fluid leaks into the radiator. i ran a trans cooler and bypassed the radiator, but i made the mistake of zip tying the trans cooler directly to the condenser at the front. the heat from the trans cooler creates high pressure in the cooling system and blows out those seals that bolt up to the compressor. 9 times out of 10 the seals go on the compressor. swap out the seals and gas it up, and if you have a trans cooler too close the the condenser get it away. i got mine regassed and made my own cooler brackets with bar aluminum and now every things gravy...

Had a similar thing happen with my VN. Aircon would turn on & off all the time. Turned out to be the refrigerant low pressure switch located on the receiver dryer. As I couldn't be bothered having the aircon system evacuated & recharged just to replace the switch, I disconnected it & inserted a bypass wire in the plug. It's work for a couple of years now, no dramas.

If its low pressure itll cut out relatively quickly to immediately depending how low it i...

and by bypassing the switch if its high pressure rather than too low.. youll blow a line possibly the compressor.. and if its too low and eventaully not refrigerant left your compressor will seize completely, the refrigerant carrys the lubricant for the compressor

[Dum*P*ster]

does this fall in the same category as me.. if i have the A/C every few seconds I hear this.. *Click.. buzz.. then nothin, 5 secs.. *click - Buzz.... then nothing, and repeats :P

Low gas, pressure?
or the compressor shitting itself , not really bothered over it tho

[89vn]

My car was doing the same thing and it turned out 2 be the low pressure switch was stuffed

[Warranty Void]

Low pressure switch isn't particularly reliable, you can get it regassed and find the same thing happens straightaway. If the thing is cooling properly then just bypass the thing with a loop of wire on the receiver/dryer as suggested earlier. If it keeps blowing hot air as it gets overworked then it's time to look at the condenser or the orifice tube might be clogged.

[Dum*P*ster]

Mine gets cold.. but, wondering if its normal to keep hearing... *CLICK-BUZZZ..(Then normal engine sound) then *CLICK-BUZZZ* etc ;p

I think the compressor disengages and then re engages as required.

Every 10 seconds? I don't think so

[Warranty Void]

Yeah that's a bit too often, innit. In that case I reckon low gas or faulty pressure switch. Try jumping the pressure switch on the reciever/dryer and see what happens.
