![]() ![]() If the clutch proves out to be good, the next thing you can check is to see if the relay itself is bad. Usually, the bearings will be the first thing to go out on the clutch. If you can manually engage the clutch by doing this, you can prove whether the clutch is working correctly. You can test the clutch by locating the relay located in the engine side fuse panel, then jump the power to the clutch pin. The clutch is designed to be turned on and off as needed. I'm not sure there is anything physically wrong with your clutch or belt. Does the fact that the clutch is only spinngin part of the time mean that I should replace the clutch? And if so, how do I do that?.Does the fact that the clutch is only spinning part of the time mean that I should replace the belt? And if so, any special requirements other than releasing the tension on the belt, remove old one and repeat for installing the new one?.Can the power supplied through the relay go in and out(causing the clutch to start and stop spinning)?.When I later turned the car off and turned it back on, the A/C clutch was intermittently spinning for a few minutes and then stopped spinning all together. After that I check the relay, and it appears to be good. From there I check the fuse, and it is still good. So I checked the clutch to see if it's spinning, and it is not. I connected a pressure gauge to the low pressure end of the A/C tubes, and the pressure wasn't dropping once I turned the car on (my understanding is that it drops as the clutch engages - if that is wrong, please correct me). ![]() A while back it was the freon according to the previous owner. R134a and R1234YF have different low pressure port types, so you should never use a recharge adapter to add the wrong type of refrigerant.My '05 Mazda Tribute (just over 200,000 miles) is having problems with the A/C. 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 2002 Protege that indicates if it requires R134a refrigerant or the newer R1234YF type to do a recharge. What type of refrigerant does a 2002 Mazda Protege use? Air conditioning systems can vary so it is critical that you check the sticker in the engine bay to determine your Protege refrigerant type. Typically the AC recharge kit you buy will have enough capacity to add enough freon to get the AC in your Protege 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 2002 Protege AC low pressure port cap, hook up the can of refrigerant to the low pressure port. How do you recharge AC in a 2002 Mazda Protege? 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 Protege 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 2002 Mazda Protege starts blowing hot air, you likely have a freon leak.
