Hi,Let`s see if we can help.Look for the ac compressor,and follow the large ac line/hose until you come to the small ac service port,this is it.The high side line/hose is the smaller line/hose with the large ac port.You can`t hook up to it any way with a single ac charge hose ,so there you go.If i can help...roniecon@gmail.com

Where to replace refrigerant; no cold air blowing


ac lines under the hood carry r134 through the ac system. there are high pressure lines and low pressure lines. each side has an opening for service. it is not uncommon for the system to lose refrigerant and either be less efficient or not work at all. to add freon to the system runs the risk of overcharging which will cause the system to run less efficient and possibly cause damage to the compressor or seals. the charging or adding of freon is always done to the low side and you can identify the low side by the size of the line. you will see there are two obvious sizes of lines. find both connection points first and make sure you know you are dealing with the larger lines which is the low pressure side. attaching to the high side could cause a can to explode and you could be injured!! with the engine running and the ac on its coldest setting with the fan at maximum speed you open the freon can with it in the upright position. verify that the compressor is engaging the clutch on the compressor. cans usually contain about 12 oz of freon. stay away from the mixes that try to give you stop leak and lubricant. try one can and see what you get. about those lines the size of the high side is like a pencil and the low side is like a magic marker. that should help you identify them. if you need more please reply and good luck

check your fluid. you may need to add fluid because when the fluid gets low it doesn't have the pressure needed to engage the transmisson gears and valve bodies.

I need to add refrigerant and would appreciate confirmation of the low pressure point of access.


It's the one with the blue cap. Your hose won't fit on the high side, so you're safe.
