Question about 1994 Jeep Grand Cherokee

1 Answer

AC Recharge I do not have cold air. I bought a can of R-134a and was going to do it myself but I cannot find a low pressure port. There is an attachment on the compressor. ( It's on the compressor, facing the battery) On the top of this attachment is the hose from the evaporator. Below this is a hex head fitting with a small hole in the end of the fitting. No cap. There is another hose on the top of the attachment that runs towards the front. Below this hose is a fitting that has a cap on it. With an "H" on the cap. I am thinking it's the hex head fitting. Am I correct? If so, then I cannot use this do it yourself bottle can I? Thanks and I look forward to hearing back from you

As far as I know, the Jeep Grand Cherokee does not have a low side port. They usually have to pump it in through the high side with a high pressure pump. You can usually get 1 or 2 cans of R-134a in it through the high side, but it only makes a small difference. I would recommend taking it to a local mechanic and having them do it. I do not have that luxury because the compressor is crack, and I do not know where; it's also several hundred dollars to fix. Hope this helped.

Air Condition not very cold.


The pressure on the low side it not very meaningful by itself.
What matters is the difference between the high and low.
The low normally can be up to 120 psi or so, and the high side can be twice that.
But when the AC is running, the low side should drop to less than when it is off.
But there could be lots of reasons for it not being very cold.
The pump clutch could be failing to engage. The release valve should be not opening. The air flaps could be letting heater air in instead of cold. The AC condenser fan fan or relay could be bad.
Etc.

Hot air comes out driver side, but cold air comes out of the passenger side


My 2000 Bonneville would do that when the pressure in the ac system was low. I had a leak in my system and bought a recharge kit and charged it when it got low. The correct way is to fix the leak of course, but this worked for me for the last 8 months until I had it fixed this week.

Air conditioner blower stopped working on 2004


If the blower works but its just not blowing cold air, its possible to recharge the AC system yourself. Most auto parts stores carry AC recharge kits. Instructions to recharge the AC are belowl

RECHARGING AC SYSTEM

1.Turn the truck on and turn AC on HIGH
2.Locate the low side AC line (will have a valve and cap similar to the cap on a tire)
3.Insert the oil or R-134A can to the hose (Do not turn the screw to puncture the can yet)
4.Insert the other end of the refill hose to the low side valve
5.Puncture the R-134A can with the screw on the refill hose
6.You should feel the system suction the refrigerant out of the can
7.Check for frost on the AC lines and the air blowing inside the truck
8.If frost develops and the air is cold, you've successfully recharged the system and disconnect the refill hose. DO NOT ADD MORE REFRIGERANT...overcharging the system will damage your compressor and will be less effective


Best of luck and enjoy your vacation.
Greg

Hopefully this answers your question and you're able to get your AC working again. Best of luck.

My recharging kit for air conditioner doesn't seem to fit recharge valve on 2004 dodge durango. How can I be sure i am looking at the low prerssure valve?


Newer vehicle come with R134 vs R12. Since the two are not compatible, R134 has larger fittings. AC system has two ports, High and Low. Low is return to AC Compressor and high is output. High port is first following line from compressor to condenser (condenser is at front of vehicle like a second radiator). Keep following line till you find high port (paint cap red). Second port is low (paint cap blue).

AC booster recharge hook-up


You can only attach the the recharge hose from the kit to the low side ( A/C service port) and the cap should be blue with a leter L on it. Good luck and follow the instruction and don't over charge the system. 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 R134a and then evacuate and recharge the system with the correct amount. Most cars have the specified amount on a decal under the hood.  Good luck and hope this helps.

Need to recharge AC, looking for recharge port?


Here is an image of the low side port I found on my 2007 Kia Spectr5. It was towards the back left when standing in front of the car with hood up. The cap had an L embossed on it. My car was blowing neutral air not cold or hot and the clutch kicked on only when the car would start. I took it to a shop for a basic pressure test and they said it was low put the system looked fine. I just bought a can of subzero and did it myself and now I freeze. The pressure was actually empty when I used the gauge and it took an 18 oz can to get me up but was still not enough to reach the recommended zone on the gauge but I figured why push it if it's blowing so cold. The can of subzero I bought had the gauge attached to it so I kept the gauge and can easily check it at any time for a basic reading. That and when it comes time to charge it again I can grab a small 12 oz can with no gauge for a much lower price and use the gauge with it. I searched every where online but had no luck finding good info or images on where to find the port, So I decided to post this retrospect for others that find this query.

How do I add coolant to the air conditioning system of my 2001 Hyundai Elantra?


You need to locate the low port on the AC.

You recharge the AC connecting to the low port.

You find the AC low pressure at the top of the compressor. Near the compressor you find two ports, the high port and low port.
You can follow the compressor line to reach the port.

To find out which one is the low port, run the air conditioner for a couple of minutes withthe engine on.
Then turn off the care and touch the lines from compressor to the two ports , often covered with plastic caps. Only one of the pipes will be cold, the line that is cold will lead you to the low port.

AC has stopped blowing cold air. Compressor is working. Where is the recharge valve located?


There are two A/C refrigerant lines. The small line is your high pressure line and the larger line is your low pressure line.
Start at the fire wall and follow the "large " low pressure line to the compressor. The low pressure charge port will be some where on that line.
DO NOT try to recharge on the high pressure side ( small line )
Good luck, let me know.
