Steps in a/c repair diagnostics

My Olds Aurora 99 A/C is blown
fuses ok
blower ok
relays ok
volume of air --good-- same as before--but not cold
I need to do the next steps in diagnosis------check the presence of the A/C gas in the low pressure system inlet by depressing the valve --and check and see if the central core of the compressor is spinning or not
Did I get the order of the diagnostics right ?
where is the comp located under the hood?--The engine belt looks connected to the alternator to me
I appreciate your help
Thanks
Dr Nitin Pandya

THIS IS A SPECIALISED JOB do not play as its extremely dangerous and you will need a special machine to recharge the gas,the most likely cause is lack of gas which will be sensed by a sensor and stop the compressor from operating so as not to damage it with no gas for cooling and lack of oil circulating.

2006 I-280. Why does A/C blow cold air only on high speed?


check fuse first
then scan PCM , oops you didnt and the BCM does run this stuff.
so not scanning it , you miss all those FACTS.

the blower is dead. (aka , not spinning , or silent)
on all cars made the answer is the same.
blown fuse, fuse marked BLower, is blown. LOL.
controls not turning it on, controls failure.
blower bad. (motor) hot wire it in place to test)
wires to any of the above.
or the resistor block bad, (if it works on high but not low)
i have the schmematic in hand.

the HVAC relay pulls in by command of the BCM
the relay then sends 12vdc power to the blower via fuse 41
the blower is now hot full time.
the blower then needs a ground to spin (run)
on high, the ground G601 via the speed knob,switch makes that ground connection, so if the fan dont spin and say the fan is ok
then the relay is not closing or the fuse 41 is blown. (why not look at the fuse first for all electric fails)
the BCM sees you, turn fan on, (heat or cold)
and closes this relay, on the left.
if the relay does not close, (and coil is ok inside)
the the BCM didnt see those HVAC requests.
use a scan tool and look for BCM errors..>??????

2002 deville has not hot or cold heat


I own a DeVille. Check your large hoses to see if they are warm when the caddi is warmed up. Do you have blowing air from your fan? If not, check the fuses and swap relays under the hood with each other to see if it a relay. You may have a bad blower motor, but check the relays and fuses first. If all those check out good, replace thermostat for warm heating. This will not effect the cold heating. Last and very important. Are you losing antifreeze? If you are, you may have a blown head gasket. 4.1Ltr engines are known for this seeing that most people do not change their antifreeze often enough. Good luck. email me at tvandenhoy@hotmail with your diagnostic results.

You may have developed a leak at the front compressor seal or another location like the condenser for instance. Have an AC repair shop hook up a set of AC diagnostic pressure gauges and see if the system pressures are ok.

No air being blown when ac or heater is turned on


Relay, switch, fuse or the motor is bad. Check fuse first, then relay, then switch. If all that fails, try the blower motor

Where does the turn signal relay plug go on a 99 olds aurora


Normaly it is under the hood on the drivers side under a plastic cover but it should easy to see and remove. If it is not there look at your fuse panel and at the top is another place ther have ther turn signal relays.

Air and heat not blowing air through vents


Either Your fan switch is burned out or you blower motor is no good, your blower motor is on the passenger side under the dash. Before you replace any parts you need to check your fuses and relays under your hood and in the car. Usually if your fan switch goes bad you will still get some air blowing thru the vents, so my guess would be blower motor, If its not a blown fuse or relay.

2001 Aurora - blows only 'warm' air


Your problem is either a clogged heater core, or the air temp control blend door actuator, in order to check for a clogged core feel the heater core hoses in the eng compartment, they should both be hot, one a little hotter than the other, if they are the core is ok and the blend door actuator needs to be replaced.
