Can't get compresser to come on..

The AC compressor will not operate if the freon charge is low. Have the system tested for proper charge. If the freon charge is ok, you may have a compressor relay, wiring, or compressor issue

A/c compresser clutch not getting power

Since the AC compressor clutch will not receive power unless the system is sufficiently changed to circulate the oil that lubricates the system components you must verify the system is not low on charge which you have not mentioned has been done. Hook up a set of AC pressure gauges and verify the system has at least a 90% full charge of refrigerant.

Ac compressor good but wont start

You must have a leak, the compressor will not run if the system is low on charge, the charge carries the oil to lube the parts of the system. Also do an electrical jumper of the compressor cycling/pressure sensing switch.

How do you add the 134a to a 1997 chevrolet lumina?

Go to wal mart $6.00 a 12 oz can,may need 2 cans. Car owners manual will tell capacity in oz of AC system never charge over that amount into your system, also PSI and ounces are not the same thing

Go to auto parts store buy R-134a charging hose kit with a gage built in.$ 10.00

Turn engine OFF Under the engine hood, is a large aluminum cannister usually on passengers side ,on it or on a hose coming out of it will be a black plastic cap,with a connect fitting under, remove cap, pull and hold back the locking ring on the charging connector and push on fitting. look at gage it will show how much freon pressure is in system, with engine and ac off a higher pressure value will be on gage Start engine and turn ac on cooldest and fan high. The pressure will drop. if the pressure drops below about 22 PSI the ac compressor will stop automatic by the low pressure cut out switch.then the pressure will build above 25 and the compressor will engage again, this is short cycling(no/off) on the low pressure sensor and is a good indicator of a low charge of refigerant(R-134a). Charge according to instructions on kit. When the pressure stays above 28 and the compressor stops cycling off your good DO NOT over charge or you can cause compressor slugging. Liquid into compressor($1200.00 for new compressor)
R-134a can cause blindness. wear goggles and gloves

The "O" ring seals in the ac system dry out when the ac is not in use for over a month and leak the refigerant out again, So Use your defrost setting in the winter because it runs the ac compressor for dehumidifying, but only after the engine has warmed up a little, or with no warmth from engine the defrost will blow freezing air.

Bad ground some where

There is a pressure switch on the side of the AC refridgerant reservoir area. If the switch is bad, or the level of refridgerant drops, the pressure switch doesn't allow the compressor to kick in. When you are running the wire from the relay to the compressor, you are bypassing the pressure switch. I am guessing that to fix your problem, you need to check the charge on the AC system, or check the pressure switch, and hopefully you will find your problem.!

The a/c Compressor Does not turn on.

There is also a low pressure switch that is incorporated into your AC system. If you have lost to much R-134 the compressor will not engage. This is to protect the compressor so it does not seize up from lack of oil. Your AC system also has ester oil in the system to lubricate the O rings and seals to keep them soft so they seal. You can jump the pressure switch to override the low pressure. If the clutch on the compressor engages then you have a low charge in your system. Or, you can place a manifold gage set on the low and hi side of the system to see what pressures you are running. If you don't know anything about head pressures then don't attempt this process. Good luck.

i wont start untill it sees substantial amount of pressure in the system try locating the ac pressure switches, should be one or two of them on the ac line unplug them and jump them with papar clips dont run for too long without refrigerant or you will damage the compressor and be sure the compressor came filled with oil or fill it yourself -jeff
