Can a bad expansion valve cause an AC compressor to run?
AC compressor constantly running. A constantly running compressor is another symptom of a possible problem with the AC expansion valve. If the AC expansion valve fails or sticks open, it will cause the compressor to pump refrigerant through the vehicle’s AC system, even when it may be undesirable for it to do so.
Do you need to change the expansion valve on an AC unit?
Also, when changing the compressor, replacement of the expansion valve is usually a requirement for warranty coverage of the new compressor. Remove or discharge any remaining refrigerant from the AC system.
Where is the a / C expansion valve located in a car?
The A/C expansion valve is found within the air conditioning system of a vehicle. The purpose of the valve is to manage how much refrigerant liquid can flow throughout this system.
What are the symptoms of a bad a / C expansion valve?
The most recognizable symptom of a bad A/C expansion valve is when you turn on your air conditioner and warm air starts blowing out of the vents. This would obviously mean that not enough refrigerant is making its way to the core of the evaporator.

How much does it cost to replace an expansion valve?
At this point, you will need to replace your A/C expansion valve to fix the problem. The replacement cost of an A/C expansion valve is anywhere from $200 to $450. The parts cost itself will be between $100 and $200 while the labor costs will be between $100 and $300.
How to tell if an expansion valve is bad?
Symptoms of a Bad or Failing Expansion Valve (Orifice Tube) 1 AC system performing worse than usual and blowing warm air. 2 Frost on AC evaporator or coming from the vents. 3 AC compressor constantly running.
How can I Check my valve clearances for noise?
To check your clearances, you can insert a thickness gauge between the valve stem and the rocker arm or lifter. If this reduces the noise, the cause is excessive clearance, and you’ll need to make the proper adjustments.
Can a refrigerant valve be replaced without removing the compressor?
Success! Yes, the valve can be replaced without removing the compressor. Mine was only held in by one hex bolt. I could have done it myself if I had the equipment and knowledge needed to evacuate and recharge the system.
Can a bad or failing expansion valve cause unmetered refrigerant?
Frost on AC evaporator or coming from the vents. Another symptom of a potential problem with the vehicle’s AC expansion valve or orifice tube is frost coming from the vehicle’s vents. If the AC evaporator or orifice tube malfunctions, it can cause refrigerant to flow unmetered through the vehicle’s AC system.
How does a Honda CRV air conditioner compressor work?
The compressor is held on by four long bolts, 14mm IIRC, then the pigtail which was disconnected when the radiator was removed. Of course the AC lines now have been undone and set off to the side. Now the compressor may be lifted a tad and it will be free to be removed.

Why is my Freon blowing from checkvalve on compressor?
HELP! A/C hasn’t been working, and the code is 18065 (P1657) “ac sytem input/output short to plus–intermettint” so the A/C never works and my wife is 8 months pregnant and its 90 degrees out. So I went out there today and hooked up a good ground and battery positive to the compressor to see if still worked.
What does a blow out disc on a compressor mean?
More than likely the compressor has failed. If that blow out disc on the compressor is blown time for a new compressor. There is an aluminum tape applied over the valve, this little “blow out disc” is an indication of impending failure of the compressor.
Is the a / C blowing hot air or the compressor is not turning on?
A/C is blowing hot air. Freon is full, compressor is not turning on. Clicking this will make more experts see the question and we will remind you when it gets answered. You can’t post conmments that contain an email address. An expert who has achieved level 1. An expert whose answer got voted for 2 times.
Why does my AC keep blowing hot air?
It started after I had the ac compressor replaced. At first it was intermittent, it would blow cold and then blow hot, blow cold then blow hot again until it just started blowing hot.
Why is cold air blowing out of my car?
If you are getting consistent cold air blowing out of the drivers side and the passengers side isn’t blowing out that same cold air, you may have a defective blend door actuator. If the system was low on refrigerant, you wouldn’t be getting consistent cold air blowing out what so ever.
What should I do if my car a / C is blowing hot air?
Check the front of your vehicle for debris, the engine cooling fans for proper operation, and your cabin air filter for debris and dirt. The refrigerant in your system also needs to be able to flow properly through the system. Check your compressor for proper operation, clogs in your system and the proper amount of refrigerant.
Where is the expansion valve on an AC unit?
The AC expansion valve is found within the air conditioning system of a vehicle. The purpose of the valve is to manage how much refrigerant liquid can flow throughout this system. Whenever there is an abundance of refrigerant, the core of the evaporator will get too cold and eventually freeze.
