The AC pressure switches are located on the AC pipes on both sides of the AC compressor. RELATED: 6 Symptoms of a Bad AC Compressor AC Pressure Switch Location Listen for the distinct clicking noises from both under your car’s dashboard and in the engine compartment, telling you that the switch is turning the compressor off and on. It will sound like the clicking occurring when the compressor normally activates, except the air won’t work. If the compressor is clicking off and on, you are going to notice some strange sounds from the engine and under your dashboard. However, this problem is also caused by low refrigerant levels, which should be checked regularly. However, when the AC pressure switch goes bad, warm air might be all you get. When you turn on the air conditioning, you expect to feel cold air pour out. However, many components make up the air conditioning system, so your problem could be entirely different. What’s worse than the air conditioning working intermittently? How about when it stops working at all? If your AC doesn’t run, the refrigerant pressure switch sensor might be defective.

Or, it might only work occasionally, leaving you hot most of the time.Įither way, when the air conditioning only offers intermittent usage, it’s a good sign that the AC pressure switch is faulty.

You might notice that the system starts up and cuts out for a short time. This AC system symptom can show up in numerous ways. R134a and R1234YF have different low pressure port types, so you should never use a recharge adapter to add the wrong type of refrigerant.Conclusion 1. You cannot add R1234YF refrigerant to a R134a system nor can you add R134a refrigerant to a R1234YF system.

There is an AC sticker in the engine bay of your 2005 Miata that indicates if it requires R134a refrigerant or the newer R1234YF type to do a recharge. What type of refrigerant does a 2005 Mazda Miata use? Air conditioning systems can vary so it is critical that you check the sticker in the engine bay to determine your Miata refrigerant type. Typically the AC recharge kit you buy will have enough capacity to add enough freon to get the AC in your Miata to blow cold air. In addition to cooling, freon lubricates the compressor when it runs. When your compressor kicks on, add freon to the correct pressure. Once you find the 2005 Miata AC low pressure port cap, hook up the can of refrigerant to the low pressure port.

How do you recharge AC in a 2005 Mazda Miata? The low side AC port location is the first thing to find when you are looking for how to put freon in a car. If there is a problem with your compressor or evaporator, adding freon will not restore cooling. The A/C system in your Miata consists of a compressor that is belt-driven, an evaporator and freon. Most refrigerants include a leak sealer that will seal small leaks in addition to filling the R134a freon. Recharging the freon in your AC system is an inexpensive and easy first step to restoring the cooling capacity of your A/C system. When the air conditioner in your 2005 Mazda Miata starts blowing hot air, you likely have a freon leak.
