Where does AC leak from car?
Where does AC leak from car?
Water: if it’s water, and you know you’ve been running the air conditioner or interior heater, it’s likely just condensation from the cooling mechanisms. Specifically, the evaporator core leaks water from under the passenger side of the engine compartment when the air conditioner is being used. This is normal use.
Where can I find the refrigerant leak in my car?
If you still haven’t found the leak, check inside your vehicle under the dash. The evaporator will be under your dash usually just after the fan blower motor and the heater core. This may be more difficult to find but you may find dye in the air vents, on the carpet, or on the cabin air filter.
Where does the leak in an air conditioner come from?
Most of the time, the leaks in the coils (whether they be outside or inside coils for an air conditioning or heat pump system) occur at the u-tubes. These are bends in copper at the end of the coil.
Why is it difficult to find a leaking capillary tube?
These leaks can be difficult to find because dis-assembly of the system is necessary to find the leaking capillary tube. Upon discovery of a leak, a cut is made in the capillary tube, the hole for the capillary tube reamed, and another larger piece of copper tubing soldered over the capillary tube.

What should the temperature of the a / C vent be?
At 100 degrees ambient, a vent temperature anywhere between 52 and 60 degrees is considered “normal”. Remember that A/C depends on transferring heat, any heat removed from the cabin must be deposited outside the car (via the condenser).
