This link refers to a 2000 Jimmy, but it's the best I've been able to find. If you're uncertain, it may be a good idea to post onto a Jimmy owners' forum and get advice from Jimmy enthusiasts.

Where is the low pressure ac port located on a 1999 grand am v6 looking down from the front of the engine


automotive ac systems have all the same basic components that house systems have , there just smaller .

if one insists on repairing there own ac system a bit of basic know how is required to work on it safely

first it works simply by compressing a gas and then forcing it over an obstruction (orifice) this cools gas then it goes thru condenser (in dash) and fan blows air over it , taking cool air away to be replaced with warm air , this causes gas to flow back to dryer then to compressor to start the process all over again (circle ) now the gas coming off compressor is high about 150 to 200 psi this is very dangerous if it gets out of pipe !! now most car systems along with home systems have two service ports that allow one to access what's inside system , this is why its sort of important to correctly id the type of service port your using , because you cant add any gas into high pressure port , but instead it will come out of that port and severely damage any thing attached to port and anyone holding it as well , now most mfg know this and purposely make the two ports different sizes (but not allways) for safety reasons , low side of the system should have around 20 to 35 psi in them this is why its very important to Id the correct fitting !!

My ac blows warm air


You need to hook up a set of AC pressure gauges to the low side charging port and read the system pressures with the AC compressor turned on and running, it should be around 28-32 PSI. If the compressor press is correct you have some other problem like a broken air temperature control blend door inside the dash air ducting.

1999 Ford Ranger AC low side pressure reads 100 psi


Was the a/c compressor running when you got this reading?

When i turn on the a/c,the compressor does not work


CHECK REFRIGERANT CHARGE. USING A MANIFOLD GAUGE SET. HOOK MANIFOLD GAUGE SET TO LOW PRESSURE PORT AND HIGH PRESSURE SIDE PORT. LOW SIDE PRESSURE SIDE SHOULD HAVE 25 - 36 PSI AND HIGH PRESSURE SIDE SHOULD BE 178 - 237 PSI. IF LOW SIDE PRESSURE SIDE READ BELOW 20 PSI THE LOW PRESSURE SWITCH WILL NOT TURN ON THE AC COMPRESSOR CLUTCH NEED TO ADD LITTLE MORE REFRIGERANT. IF REFRIGERANT LEVEL CORRECT CHECK AC COMPRESSOR FUSE AND RELAY.IF POWER GOING TO AC COMPRESSOR CLUTCH YOUR COMPRESSOR CLUTCH HAS OPEN WINDING. AC COMPRESSOR CLUTCH NEED REPLACING.

What are the AC pressures supposed to be on a 2000 Monte Carlo?


On hot day @ 85=+ degrees it should be between 45 to 50 pounds on the low side pressure port

2000 Golf gls 4D AC static reading 100 psi, with the engine start and compressor working low reading 35 psi. The A/C blows warm for about 5 to 10 mins after that it can blows cold... problem with...


only 100 psi ,should be around the 200 mark ,i suspect that you could be low on gas ,forget these cans from supermarket and have it checked out with the correct machinery ,have it emptied out and vacumned up then reiflled to the correct weight of gas for this vehicle which i think should be 750 grms R134 then test for pressure and i have a funny feeling it will work correctly ,

2009 toyota sienna, a/c doesn't work. i have lready replaced the compressor,clutch,relay, expansion valve and drier....still not working....even the toyota dealership her in las vegas is puzzled why it...


does the fan blow air in the cab i know its not cold but it is air? does the air lines compressor sweat? it may be the air conditioning button in the car where turn ac on off is not sending signal to compressor to turn on compressor and check the air ducts make sure they routing the air correctly to the cab check to make sure a ac system is not over charged if it is over charged will not send out cold air use a tire gauge should be around 40 psi i believe but check with dealer make sure my psi is correct hope this helps if dont fix repost and think somemore ideas

A/c recharge what is thew psi for refrigerant


Below are normal car AC pressure readings with 134A.

Normal readings on high and low side with AC OFF (static pressure) – Depends on outside temperature, but normally is between 80-105 PSI

Normal low side reading with AC on high speed and MAX & engine at 800-1000 RPM’s – Ranges from 25-35 PSI

Normal high side reading ranges from 200-350 PSI
Don’t assume that if adding little Freon is good that adding a lot is better! Overcharging just a little can decrease the performance of the system and possibly damage the compressor.

With the AC on the coldest setting, use a thermometer in a middle vent. Normal vent temperature readings will vary depending on the (ambient) outside temp. The vent temperature should range from around 42-55 degrees in my experience.

If normal gauge readings are obtained and the vent air is cold – STOP don’t overcharge the system. The only proper way to remove refrigerant is with a AC recovery machine so if this is being done at home I can’t emphasize enough not to over charge the system.

Thank you for using fixya and be safe.

Ac compressor took one can of freon will not take other also it still is not cool


You may have over charged the system, An over charged system will also give you poor A/C performance and worst can lead to expensive repair if the compressor get's damaged.
 With the AC on the coldest setting, use a thermometer in a middle vent. Normal vent temperature readings will vary depending on the (ambient) outside temp. The vent temperature should range from around 42-55 degrees in my experience. If normal gauge readings are obtained and the vent air is cold - STOP don’t overcharge the system. The only proper way to remove refrigerant is with a AC recovery machine so if this is being done at home I can’t emphasize enough not to over charge the system. And actually the best way to insure the proper charge is in a system, is to use an AC machine to recover the freon and then evacuate and recharge the system with the correct amount. Most cars have the specified amount on a decal under the hood. 
Normal readings on high and low side with AC OFF (static pressure) - Depends on outside temperature, but normally is between 80-105 PSI
Normal low side reading with AC on high speed and MAX & engine at 800-1000 RPM’s - Ranges from 25-35 PSI - Note that on many Chrysler products a normal reading on the low side may be 15-25 PSI
Normal high side reading ranges from 200-350 PSI

Don’t assume that if adding little Freon is good that adding a lot is better!  Overcharging just a little can decrease the performance of the system and possibly damage the compressor.

God luck and hope this helps.
