The low A/C service port is located on the A/C accumulator, that's the silver canister on the passenger side just in front of the blower motor housing. Here is a link and #6 is the accumulator. http://www.compnine.com/index.php?u...delid=6872&capuid=1&majorgroup=09&grouptype=B

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.

Here is the safest way to recharge your A/C without the two gauges to get a high and low reading.

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.:eek:
