So on a 2014 Chevy Silverado Lt,the expansion valve needs o rings on the inside too

[@beautifulvictory4eva185]

Thanks and have a stupendous day! ❤

[@riadomerasevic3877]

greetings. passat cc, when the air conditioner is turned on at 22 degrees, a sound like a beep is heard, when the temperature drops below 22, the sound stops, is it possible that it is due to the valve

[@Babyface_lc]

Mine make a flat tire noise😅

[@TheodoreRizzo]

Who turn its air conditioning at 22 degrees? I’ll have my heater on.

When my blower motor was working it blew cold out of driverside and warm out of passenger. No matter if ac was off and blower adjustment didnt make a diffference. It would blow heat until i started pushing vent choices and the man/aut environment inside control button. Temp guage dial didnt make a difference either it was just luke warm and colder on other side. Before that it was a some timer on and off along with console vent control lights. I push defrost button and it shut off when it did blow it was cold air. Im thinking i have several issues but im strting with blower motor. Its getting power to it but wont work any more. Im hoping that will solve mos of m issues since winter is here and i need defrost and heat. My coolant level was low but still only somewhat warm on one side. Ant suggestions. My radio volum rises when i shift out of park. Short in consle? I left sunroof opened and it rained could have something to do with it. But not both temps at same time.

Check the blend door motor that operates the blend door on the side that doesn’t have the temp change.

[@adamtaliat6139]

I use s500 w220 the ac cool from the passenger side but hot at the driver side how can you help me please

[@easyautofix]

Since your vehicle is experiencing cooling on the passenger side but hot air on the driver side, the problem is likely related to the dual-zone climate control system, with a malfunctioning blend door actuator being the most probable cause. This is an informed guess based on common issues; careful diagnosis is still recommended for accurate troubleshooting. Remember, the dual-zone system allows for separate temperature controls for each side, which is why issues like this can occur.

[@markwoodruff6334]

I have a loud hissing sound coming from the right rear interior, 2013 Ford expedition limited. I believe it to be the sound of refrigerant moving through the lines versus a leak. Plus my control panel will not turn the unit off until the key switch is turned off. Also it does leak down slowly during cool weather, faster during hot weather. Plus the noise is louder during hot weather. Thanks

[@easyautofix]

I have seen this happen when the system is low on refrigerant. Filling it up to normal levels fixed the problem. In other situations, it's due to a leak in the system. You can try adding UV dye to the system to help find the leak.

[@zoro__gaming7459]

In my car hp hose getting cool abd lp hose getting heat and ac also not working what is the problem tell me sir

[@BlackWolverine11]

Most likely a restriction check the condenser for damage (ie bent fins or housing) you might also have a restriction caused by metal from your ac compressor from internal wear

[@Khaiel1x]

Hey man, u got discord or something so I can show u my issue. I can show u the sounds and all the info and maybe u can lend me a hint for direction? Thanks

[@soheilzamani17]

I have a rhythmic humming/vibration sound only when the AC is on. It gets a little worse as the AC stays on longer. When I turn the AC off the sound immediately goes away so it is definitely related to the AC. It’s a 2011 E90 328i and it was low on refrigerant so I recharged it 2 weeks ago. It’s blowing cold air now. The noise has been present before and after the recharge. What is that likely to be?

[@nstorm2415]

Did you manage to fix that?

[@soheilzamani17]

@@nstorm2415 haven’t figured it out yet. Why do you have the same issue?

[@nstorm2415]

@@soheilzamani17 kinda. It sounds like a grinding/hissing that only appears for a moment and it goes and comes while im driving with the ac on. Sometimes it also makes a noise like metal grinding.

[@soheilzamani17]

@@nstorm2415 keep me posted if you ever figure it out. I’ll do the same.

@@soheilzamani17 hy, i replaced the expansion valve and the sound disappeared. I bought an original one (denso).

[@kalani1987]

Thanks for this. An independent shop charged me almost 300 to change the expansion valve out. Is this reasonable? It is accessible on the firewall

[@jorgerojas5702]

Well they are also performing a vacuum and a refill of the refrigerant

[@All-about-everything]

I had my whole ac system swapped out for 450

[@All-about-everything]

I did my own vaccume and recharge tho

[@jbuck1975]

​@@All-about-everythinghow did you do the vacuum? We are changing the evaporator core and will need to vacuum before recharging

If other components can cause similar symptoms and I can’t isolate the symptoms to the expansion valve what’s the point of the video
