I dought it is the a/c leaking there, It is probably a leak in the cowl or windshield. Get inside with a flash light and have someone spray the out side with a hose and see where it is comming in. if it is leaking antifreeze it is a bad heater core
There are only two possibilities for the water leak in the 1993 Mercury Marquis. The car could have a leak allowing rain water in. Or, the drain for the ac could be stopped, and condensation is leaking into the car. The condensation is your most likely cause.
The "antifreeze smell out the AC vents" would mean only one thing, you have a small leak in the heater core.
There are lots of places that can leak freon and some can be sealed with stop leak. The only way is to try it.
They can get noisy and leak oil. You want to replace a noisy ac compressor before it fills the system with metal trash.
This means that you have a gas leak somewhere in the engine compartment. The smell comes from the AC air inlet pumping in fresh air from the engine compartment, which is where the leak is. Check your injector o-rings for deterioration. Also check your fuel pressure regulator and lines.
You cant
spark plug gap Can also be a vacuum leak.
can you block the high side on the ac on a car to stop a leak
This normally indicates a refrigerant leak. STOP USING YOUR AC IMMEDIATELY AFTER THE ACKNOWLEDGEMENT OF THIS SMELL!! The fumes from the fluid in your AC system are highly toxic. The leak needs to be sorted out before the AC can be used again.
v have to check the blower motor,ac pipe lines and cluster assembly
There is obviously a leak somewhere
Because it probably has a leak if you have just fixed a leak then you need to put a vacuum on your AC system before you can charge it.
you have an AC leak
because of condensation
Low Freon - Your AC system has a leak .The low pressure switch is working.
If the AC in your car is not cooling, chances are your air conditioner is needing repair. You probably have a pin hole leak in the core of your car's heater. If your car has a cabin filter, be sure it is clean or replaced with a new filter.
your drain line for your ac evaporator core is plugged up. A service station can blow this out for you.
