Tried Recharging A/C and hear a hissing sound
처리 내용
Try looking at the Schrader valve in the fitting. If the hissing is coming from there, quickly and lightly press on the valve to help it seat. This is a common issue especially on older vehicles when debris gets caught in the valve. Check under the hood for the black sticker that shows refrigerant specs. Compare that to the amount added from the can. Some only take a few ounces while some take 2 or more pounds. When it comes to sealant, don’t use it because it clogs AC recovery machines and no shop will want to work on your system. You might want to consider a vacuum pump and a proper set of AC gauges. The pump will help diagnose whether you have a leak or not, and will ensure all water and air are removed from the system. AC compressors are not designed to handle moisture and will fail. Run the pump for about 10 minutes, close the service valve and wait another 15. If your gauges continue to read 30in Hg, you don’t have a leak, and are ready to recharge.

Very hot outside. Started car with a/c already on full blast (factor?). Car started shaking, put it in reverse to backup and steering wheel VERY hard to turn and brakes VERY hard to apply. Turned a/c and car off, waited 5 minutes, started it again and drove home with no a/c and no further issues. This has happened before. What is wrong? Help!! And Thank You!!

The contact owns a 2018 Toyota Camry. The contact stated that after shifting into park, the air condition system was activated, and the engine revved with the RPM elevated. The contact turned off the A/C and then turned off the vehicle. The vehicle was restarted, and the check engine warning light illuminated. Additionally, the contact stated that while the accelerator pedal was depressed, the vehicle inadvertently accelerated at rapid speed then decelerated without warning. The vehicle was taken to the dealer however, the contact stated that no diagnostic test was performed due to the cost. T

Blowing warm air. Compressor clutch engages when air turned on. I replaced the clutch coil last summer. Low side reading ~39 High side ~45. Low side does react (very little) when RPM is increased, high side does not. Most of my findings lead me to believe that the compressor is bad but I also know that low freon will make my high side low. Car (98 grand-prix se 3.1) only has 49k miles on it and I feel the compressor should still be good (that’s partly my wallet talking as well). Should I gamble and try to add freon and see if it improves? Replacing the comp and related items is just not a fina

I've taken my car to 3 different A/C shops and they were all unable to diagnose the problem. It's a BMW 1-series F20 LCI B47. Compressor is a magnetic clutch type Denso 6SAS14A. Symptoms: The AC compressor goes into "reduced mode" at higher-than-idle RPM. Once the RPM is dropped back to idle the AC restarts. If the RPM is returned from the "High Zone" to "Working Zone" the AC still doesn't restart, only when it returns to "Idle Zone". The actual RPM limit of the "Working Zone" depends on outside temperature. If ambient temperature is 20C it wor
