2008 VW Jetta AC not cold

ANSWER : Hi Allen. By far the best way to have your AC system correctly diagnosed is by having an AC inspection completed first. By having one of our professional mobile mechanics come to your location to diagnose the issue correctly, it significantly minimizes the mistakes in completing the wrong service. In your case, the issue could be as simple as needing to have the AC system recharged, or there is an existing leak that needs to be repaired before refilling the refrigerant. Best economic bet is to have the AC inspection completed first.

ANSWER : Hello, thank you for writing in. There are so many different codes being triggered, that it is unlikely all of these systems are having issues at once. We need to focus in on the fact the engine is overheating at all. You will want to check the level and condition of the coolant and the overflow tank. If the level is full then you may have an issue with the thermostat, radiator cap, or water pump. These can all be tested and changed relatively easily. If the main cooling system is okay, you will want to look into the heater core and climate control module. For more diagnostic help, contact our service department to schedule an appointment.

ANSWER : Based on the information you provided for your 2010 Dodge Avenger. It is likely that you have a leak in the air conditioning system. You may also have a resistor pack going bad, or the selector switch itself could be going bad. To have the problem verified, a certified technician from YourMechanic can come to your home or office to detect any leaks and make needed repairs.

ANSWER : Hi there. In both cases, when an AC system is not working and a warning light is coming on the dashboard, typically a professional mechanic will complete the same initial inspection, which is to download the stored error codes that triggered the warning light initially. This tends to give them an idea as to what is causing the problems. This could be something as simple as an electrical relay that is faulty or loose or an indication of a computer related "glitch". Either way, the best way to move forward is to have a professional mobile mechanic complete a check engine light inspection.

ANSWER : It is possible that since you had a leaking O-ring, not only did the refrigerant leak out, but the outside atmosphere contaminated the receiver/dryer in your A/C system. The job of the receiver/dryer is to absorb any moisture and contamination inside the A/C system. If your o-ring was leaking for a time, the receiver/dryer may need to be replaced. A contaminated receiver/dryer can will effect the efficiency of your A/C system.

It is also possible you may have another leak somewhere in the system. Try to get your A/C system dye tested. They will put a UV fluorescent dye in the system along with the refrigerant. If there is another refrigerant leak somewhere, the dye will come out with it and be visible under UV light.

If you decide to get this fixed, consider YourMechanic, as a certified technician can come to your home or office to diagnose the issue with your A/C. Good luck.

ANSWER : Hello, thank you for writing in. Although the pulley is still spinning, the compressor has likely failed. If it is not properly regulating pressure in the system, one of the first signs is a warm air conditioner. Considering yours is not cooling off, the pressures are not correct. If you believe the compressor is working correctly, you may want to check for a clogged line before replacing it. Keep in mind, a blocked line has likely put extra strain on the compressor, and may cause premature failure. For more help with testing or replacing the compressor, contact our service department to schedule an appointment.

ANSWER : Hi there. In most cases, this problem is caused by air flow to the AC condenser. If you have a condenser that is clogged with bugs and dirt this could be the source of your problem as well. It is probably a good idea to have a professional mechanic come to your location to complete an AC is not working correctly inspection.

ANSWER : Have a certified mechanic, such as one from YourMechanic, check the air conditioning system pressures for a low charge situation. The electrical side should also be inspected for blown fuses or broken wires. We recommend that you do not tackle this service on your own as the air conditioning system is charged by a gas that will harm the environment and should be handled accordingly.
