The lumina uses a compressor mounted "cut out switch." How did you charge your A/C through a HEATER?

Your car does not have a low pressure cycling switch because the compressor never cycles, the Lumina model along with many others uses a variable displacement compressor, in this case the V5 (variable, 5 cylinder.) The compressor has a control valve on it that senses low side (suction) pressure. When the suction pressure drops to the set point discharge pressure is routed into the compressor crankcase where it pushes against the backs of the pistons and compresses a spring on the swash plate. Since the pistons are no longer moving all the way down with each stroke the compressor pumps less.

On a vehicle with a properly working variable compressor the clutch engages when you turn on the A/C and never disengages unless you shut the car or A/C off, it also disengages if you go wide open throttle.

Where is the AC low port on a 2005 Yukon Dinali I've worked on lots of ACs it's not in the same spot as they normally are on our vehicle they are someplace odd where


It is in the larger of the two AC hoses (low pressure line) from the AC compressor near the firewall. The charge ports are size coded so you can't hook it up wrong when charging.

A/c low side service point


the low side charging port for the a/c is near the accumulator/receiver, dryer canister. in the larger a/c line. good-day ! the larger hose coming from a/c if you follow it back, you will run into the low pressure port. the a/c fitting, will only fit the low side so you cant get it wrong.

Is the low pressure side of 92 F-150 on the condenser or near the compressor.


LOW PRESSURE SIDE IS THE SUCTION CHARGE SIDE WILL BE FROM AC COMPRESSOR REFRIGERANT LINE TO THE ACCUMULATOR OR DRIER TO THE EVAPORATOR IN THE FIRE WALL THE AC COMPRESSOR LINE TO THE CONDENSOR IS THE HIGH PRESSURE SIDE YOUR DISCHARGE SIDE. DONT DONT TRY CHARGING AC SYSTEM AT THE HIGH PRESSURE SIDE. CHARGE AT THE LOW PRESSURE SIDE.

Where can I find the low port to recharge my AC on my 2000 chevy blazer


The low pressure port on an AC system is between the evaporator and the compressor. The evaporator is the cooling coil in the dash. I believe you will find an accumulator just on the "out" side of the evaporator. The accumulator is a round aluminum container about 4 in. in diameter and about 7 in tall. It has a tube from the evaporator going in near the top, a tube/hose going from the accum. to the compressor and probably a pressure switch and a charging port. All these items are located around the top of the accumulator. That charging port is the low pressure, (suction side of the compressor). Don't over charge. Use just enough to get cold air from the system. I doubt this system has a sight glass in the tube near the condensor, but if it does, put in just enough refrigerant to where you no longer see bubles going past the sight glass. If this is a cronic leak, you must have the leak repaired. It is aginst the law to recharge AC systems without repairing the leak.

Thanks for using FixYa. Good luck.

Where is the intake port for freon in 2000 ford expedition


The AC is charged with R134 refrigerant through the low pressure side of the system, the charging port is on the Accumulator/Receiver Dryer, this is a round canister under the hood on the drivers side near the rear of the engine bay. Below is a picture of the Accumulator so you can ID it.

A/c wont come on


have the system charge checked, the system waring is activated by this condition in most cases, u can confirm that by putting a jumper wire across the low pressure AC compressor cycling switch located in the low pressure line from the compressor near the accumulator.
