Truck Air Conditioners
If your truck’s air conditioner is blowing only warm air and no cool air, one among several reasons could be the cause of your air conditioning problem. One of these reasons could be that your air conditioner may have lost its charge of refrigerant. This is probably the most common cause of a no cooling problem. Another problem could be that your air conditioner’s compressor does not engage when you turn on the air conditioner. This could be as a result of an electrical fault in the magnetic clutch that drives the compressor. Whatever the cause, we can be able to diagnose and fix the problem by doing the following.
Our technicians will always start with the compressor to find out if it engages when you turn on the air conditioner. If it does, then the compressor is fine so the problem could be inside the unit. They will replace the motor that controls the blend air door. If the compressor fails to engage when you turn your air conditioner on, our technicians will try to find out if it will run by jumping the compressor clutch wire directly to the battery. If the compressor functions when jumped and the air conditioner blows cold air, the system contains refrigerant and the problem is likely a bad air conditioner compressor clutch relay.
Our technicians will connect an air conditioner pressure gauge to the service port positioned in the high-pressure hose that runs between the compressor and condenser in the front engine compartment. The gauge tells the technician if there is any pressure in the system. You need our professional help here because simply depressing the service-fitting regulator with a miniature screwdriver to see if any refrigerant spurts out is not an accurate check because it will not tell you how much pressure is in the system. If your AC system is out of refrigerant, we will check for leaks then have your system vacuum expelled to remove air. Once the air is out, we can then recharge your truck’s air conditioner with refrigerant. We get the air out because it reduces cooling efficiency and may make your compressor loud.
Air conditioning gauge interpretations
In order to determine the low side and high side pressures inside your truck’s air conditioning system, our technicians will use an air conditioner gauge set. They must first connect this set to your truck’s air conditioner’s service ports to read the pressures while the system runs. With your engine off, they will connect the air conditioner gauge set high-pressure hose to the high side service port situated in the compressor output line that goes from the compressor to the condenser.
