Basic Troubleshooting Tips for Your Automotive Air Conditioner

If your automotive air conditioner isn't working quite right, here are a few ideas to begin. First of all start with the operate panel on your dashboard. Most automobiles have an A/C button that assuredly turns the compressor on and allows cold air to be circulated. You might have accidentally hit the recirculation button instead of the A/C button. (Don't laugh, I had a friend that spent a week in a hot car and all he needed to do was press the right button.)

The second thing to check is the actual function of the controls. Do they move at all? Are they loose and giggle around? The big interrogate is "do they feel different from the last time your air conditioner worked?" This could tell if the controls are messed up and need replacing. Your air conditioner system may be fine but the controls could be frozen or broken. If your controls seem to be functioning, lets move to the blower fan. Turn on your car and start you're air conditioner as you ordinarily would. Then turn your blower to it's top setting. Can you here your fan blowing? If you can hear it, does it sound weak or whining. This could signal that your blower motor is malfunctioning or needs to be replaced. If it doesn't work at all, check the fuse for the blower motor. The fuse for your blower motor should be located in the fuse box under the dash.

Most automobiles have the fuses clearly labeled. First take out the blower fan fuse with the discharge tool provided in the fuse box. A blown fuse should be easy to identify. Any way if you are unsure, replace it with a similar rated fuse and try your blower again. If that fuse blows you may have a bad blower motor or a short in the circuit. In this case, you will need an authorized mechanic to fix it.

If the blower fan is working properly and you can only get cold air out of the defroster vents, you may have vacuum-system provide line problem. To check for this, look for a small black plastic tube going from the engine area through the dash. It is ordinarily right by the refrigerant lines. Check this tube and see if it has holes or is not connected. If all of these exiguous tips are not helping and you're A/C doesn't blow cold air no matter how many switches you turn on or off, you will probably need an certified mechanic. Good luck and stay cool!

This will consist of the compressor, the evaporator, hoses and belts and the troubleshooting guide will indicate tell-tale signs that your system needs servicing. Forewarned is forearmed in this regard, so reading the manual makes sense.
• Irrespective of how your system is running, make sure you have it serviced at least once a year, normally in spring. A quick check will highlight any pending problems and a fix job before summer will be the most important factor in keeping your cool.
• In the cooler months where your air-conditioner is not commonly used, turn it on for at least 10 minutes once a month to keep the hoses from hardening. Make sure you turn the thermostat to the coldest temperature and that you run it at the top fan speed.
• Run your car's defrost for 5 to 10 minutes after you have been using your air-conditioner for an extended period. This will dry out the evaporator core which is a good maintenance step for your air-conditioner.

The older your vehicle is the more likely you are to contact a slow leakage of refrigerant. You need to have your system checked by a scholar because leakages can be highly difficult to detect. Make sure you take your vehicle to a reputable servicing agent because this scholar attentiveness can become quite expensive.

turn Your Automotive Air Conditioner from R-12 to R-134 Refrigerant

If you have an older car it may have R12 refrigerant in the air conditioner system. You can still buy R12, but it is very expensive. If you are ready to turn your ideas to R134, here is a brief explanation of the procedure with a few insider tips to help you. To begin you will need a conversion kit with all the primary materials. It will include: 2 new adapter fittings, 2 -3 cans of R-134, and a hose with adapter. Once you have all the materials, you can begin the process. The first thing you have to do is have the R12 recovered with a refrigerant rescue machine. (It is illegal to just open the valve and let it out in the air.) Now that the air conditioning ideas has no pressure, it is time to install the new valve kit. At this point some people frost up (no pun intended) because they are afraid of mixing up the adapters on the high and low pressure ends. Don't worry, they are distinct sizes. The bigger one goes on the low pressure side of the ideas and the refrigerant hose will only connect to the low side valve. It is pretty hard to mess this up.

Now that the adapter valves are connected, it is time to start the car and put the air conditioner on high. Turn the blower fan to its top setting as well and open the windows. Grab a can of R134 and hook up the hose and T valve that came with your kit. With the hose hooked up to the can begin to twist the T valve until it punctures the can. Then open the valve to let some freon out and purge the air in the line. Turn the can upside down and hook it up to the low side adapter valve. Now gently open the valve and let the Freon flow into the system. At this point the compressor will begin to cycle on and off. Don't panic, this is normal. Keep adding Freon until the ideas begins to cool. You can feel the low pressure line begin to get cool and condensation will acquire on it. (Do not grab the high pressure line. It can burn you.) You probably will not need all 3 cans and be just not to overfill the system. If the air conditioner is still not cooling after the second can, something is wrong. You may have a leak in the ideas or some other difficulty.

Compressor Troubleshooting Chart

Do not be tempted to keep pumping Freon in the lines. If the low side line is cold and dripping with moisture you are done. If you have a air conditioning multiple gauge set, the low side should have a pressure of 40 - 50 psi.

Good luck and stay cool!
