Where is the low side ac port to charge rear of vehicle


The rear AC is supplied from the same compressor and charged through the same low side port under the hood, so if the front AC works ok then the problem is not a low refrigerant level in the system you have other issues like a sticking blend door or failed blend door actuator.

My car didn't take the R-134a


If your car ac is not taking in refrigerant, it could be caused by several things.
If you have recently done work on the system and you are going to fill the system the first time, you will need to pull a very deep vacuum before trying to charge in refrigerant. If you have already properly evacuated the system and having problems getting the correct charge adjusted, you may be having problem with pressure equilizing between the refrigerant source and your ac system. To get the refrigerant going again, you need to connect the charging hose on the low pressure side of the ac system and turn the fan and ac on cool. The pressure in the ac system on the low pressure side will get lower than the pressure in the refrigerant container and flow will start. When charging initially, charge liquid on the high pressure side and with the ac system running, charge gas on the low pressure side. To charge liquid, invert most container so spout is down, to charge gas, keep container right side up. Charging by gas help you to not over charge your system. Beware on most vehicle ac systems the suction and discharge connections are two different sizes and require the proper adapter. If you still having problems creating a pressure difference to move refrigerant, you can try immersing the refrigerant container in warm water or applying warm air to the exterior of the container.
Hope this helps.

A/C blowing hot air


The first thing you need done is to have the AC system charge checked, this requires a set of AC pressure gauges. A low charge is the most common cause of not cold air, a low charge on most GM is due to a failed AC compressor front seal or condenser core breach.

How does a person short out the low presure switch on a 1995 cadillac a/c? i would really appreciate any help on this.


The low pressure switch is located on the accumulator, and you only need to remove the connector to the low pressure switch and jumper the wire connector to by-pass the low pressure switch, however I would not recommend doing so because it is there to keep the AC compressor from being damaged due to running it low on R-134a.

If you are trying to charge the AC system you do not need to by-pass the low pressure switch, just start the vehicle and turn the AC on to maximum, then charge the AC system and when there is enough pressure in the system the compressor will come on, and then just continue to fully charge the AC system.

Air conditioner input won't take freon


Is the ac compressor coming on when you are trying to charge the system?I have never seen a ac service port clogged up.Are you sure the ac system needs freon?A set of ac gauges is the best way to tell.Are you using ac gauges,or just a single charge hose?There are reasons for this problem you are having,but I need some information,If you would,let me know,roniecon@gmail.com

Charging issues


Recommend istall dye into system,charge with just enough r134-A (cheapest at walmart.then let ac run for 30 min. after that inspect with black light for a green substance at all ac components.if none found look at ac drain for green residue.Best way to isolate ac leaks.
