Repairing a clogged car AC condenser needs special attention and analysis of the condenser structure as a whole. The system in which the car AC works will have many parts, each adding to a single stage of the cooling process.
Splitting the Cooling System
The compressor is the first unit of the cooling system and its function is to make sure that by driving power from the belt driven from the crankshaft of the engine. Once we turn the AC on, the compressor will use high pressure and heat to vaporize the refrigerant stored in the same.
The condenser will then convert the vapor into liquid form; this is performed with the help of the fans inside the engine grille and the radiator. Moisture is taken from the liquid refrigerant in the drier receiver cabinet, as moisture is a danger to our blood stream.
Pressure is then taken out from the dried refrigerant at the valve and converts into vapor again. The evaporator will absorb the heat using this low-pressure vapor and supply the cooler air inside the vehicle.
Condensers are known to get clogged with the remains of the high pressure refrigerant and other particle residues. Since the condenser functions as a conversion section for the AC system, the residues will stay at the bottom of the condenser. The condenser will then become vulnerable to the effects of the residual sticky paste like formation which will hinder the conversion process further. The results of this clogging will be the improper operation of the same along with foul smelling air circulation. The conversion should be performed completely and if not, the air we inhale from the AC unit is likely to cause blood freezing and cholesterol blockage in the blood stream.
Fixing the Condenser Clogging Problem
Open the engine hood and have access to the radiator system of the vehicle. This will be the area where the condensers are found in most of the vehicles manufactured these days. Disconnect the in and out pipes of the condenser unit.
Find the condenser inside the protective cover beside the radiator grille. The same might also be found above the radiator in some situations. Wherever the condenser is located, we have to gain access to the part so that we can dismantle the condenser section alone without disturbing the other components of the engine or the AC system.
Remove the screws and lift the protective cover; lift the condenser unit away from the radiator grille. Open the box hinges in it and wipe the residue seen at the bottom of the plate in it. This will clean the bottom section of condenser.
Take out the clippings inside to dismantle the condenser module from the box covering. This should be cleaned well with the soft dry cloth. Clean the entry and exit pipes of the air flow duct in the box cover to allow easier motion flow of the vapor / liquid refrigerant.
