Note the fuse responsible for the cigarette lighter. We will show where the fuse and relay boxes in the Volkswagen Passat B8 are located, their diagrams and photographs. R134a and R1234YF have different low pressure port types, so you should never use a recharge adapter to add the wrong type of refrigerant.Volkswagen Passat B8 is the 8th generation of the Passat series. 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 2014 Passat that indicates if it requires R134a refrigerant or the newer R1234YF type to do a recharge. What type of refrigerant does a 2014 Volkswagen Passat use? Air conditioning systems can vary so it is critical that you check the sticker in the engine bay to determine your Passat refrigerant type. Typically the AC recharge kit you buy will have enough capacity to add enough freon to get the AC in your Passat 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 2014 Passat AC low pressure port cap, hook up the can of refrigerant to the low pressure port. How do you recharge AC in a 2014 Volkswagen Passat? 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 Passat 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 2014 Volkswagen Passat starts blowing hot air, you likely have a freon leak.
