If the compressor is not coming on at all it could be that you are low of refrigerant and just need to add some more.
You can add Freon to your 1999 Chevrolet S 10 pickup truck cooling system, through the air conditioning compressor ports. The ports are located on the top of the compressor. You would add r134 refrigerant through the low pressure port located on the accumulator/dryer.
check the back of the compressor, they hide the there on the older models. volvodoctor
The 2000 Chevrolet Silverado truck has two ports on top of the air conditioner compressor. You will add Freon through the low pressure port.
Quick release fitting located on the low pressure side (Larger hose from compressor)
The low pressure side is located on the compressor. To locate the port, jack up the driver side and crawl underneath to locate the compressor. Add the freon to the port on the compressor.
Surge is a point when compressor is not add enough energy to overcome system resistance.
Remove the compressor and pour it in. If its making noise its probably to late and you will need to replace it.
If you add anything other than what the manufacture has no liability for defective. Meaning that if you bought a new or remanufactured compressor and it went bad it would not have a warranty.
the port to add freon is under the car in front of engine coming off the compressor hard to get to but can be done
Its always best to drain the oil from the old compressor and then add that same amount back to the new compressor but to be on the safe side add 4 ounces and prime it on the bench first...
Empty, 8 oz. If you're replacing one major part such as a compressor, condenser, evaporator or accumulator, add 3 oz.
of course you can Are you stuck ? How ?
Needs to be done by person certified to handle refridgerant properly evacuate system replace compressor vaccuum system and leak check properly add correct type and amound of compressor oil properly add refridgerant
take off starter add shim directly under the 2 bolts, retorque bolts to spec
You add freon to the low side fitting,top front,on the ac compressor
There will be two couplers on the system. The one you add freon to is the larger one on the low pressure line. From your compressor, there are two lines, the low pressure is the larger one. Check it and you will find a coupler between the compressor and the firewall.
If you're only replacing the compressor and you did't blow a hose or something, 3-4 ounces should do it. It is recommended to replace the receiver/drier and orifice tube when replacing the compressor. In which case you would add 1-2 ounces more plus the 3-4 ounces for the compressor.
The low pressure side.
The air conditioner compressor has two fittings. You can add refrigerant to the low port fitting. The air conditioner compressor can be found on the right hand side of the engine near the front.
Amount of compressor replacement oilFrom what I've read in other AC Manuals and what I've practiced, with regards to the amount of refrigerant oil to add, is to add the same amount that you drain from the old compressor unit that you removed from your system. This amount, from my experience is about 5 oz, however, it varies from compressor to compressor. The most accurate way to asses this, short of contacting the compressor mfg, is to apply what I said in the first sentence. add 6 ounces for a single ac system and 10 to 12 ounces for a vehicle w/rear air.(like surburbans, vans etc.)
