Ol' Blue,

Please add me to the long list of evap woes and send me the directions. I have a 2000 XJ.
thanks!

 

I'll send you a PM, and Welcome to CF.

I live in SC and it's already in the 90's!!! I went through last summer and it was HOT!!! I think I am ready to take this on. I have a 2000 Cherokee Sport. Add me to the "List of Evaporator Woes".

 

Welcome to CF.
Okay, you're on the list.

I can also send you a Private Message.

 

To add some more information, we added the correct amount of PAG oil to each component as directed per the manual with the exception of the compressor which was not removed. Added the freon, had pressure in the ball park but still hot air coming out of the vents. I remember a post about the blend door and investigated. Well I somehow lost the plug to drive this door. It must be tucked behind the duct. Hmmmm, just decided to remove the little clip and drop the linkage. Then just manually moved the door one way then the other to find the cold air. We now have 48 degree air coming out the vents at 95 degrees ambient. The look on my son's face was priceless.

 

O"l blue I have a 1999 Grand Cherokee limited with a bad leak problem not sure where it is but am fearful it is the Evap core. Can you send me the pdf or file to replacing core if needed?

 

Hope I am doing this right. I think I may have the evaporator core issue also. I have a 1999 Jeep Grand Cherokee limited 4.0 Any help will be greatly appreciated. Thanx

 

That's great, now you need to find & fix it so it works automatically.

I much appreciate any info that is available be sent my way. I have to pull my dash apart and replace the evaporator and the accumulator.

I'll send you a PM. Hope it's helpful.

 

I am a lurker, but have a Florida a/c problem and looking for help before I dehydrate. I have had a small pinhole leak since I bought my 99 a few years back always patched with can of r134, suddendly a few days ago there was a horrible vibration and noise that went away when the a/c was shut off and clutch disengaged. With the hood open and the A/C on the clutch engages and I can hear the building noise coming from the compressor then there is a discharge of pressure from what I assume is a pressure relief valve. I tried evacuating some pressure into correct collection/recovery tank. Once done then the clutch does the low freon clutch cycling but as soon as it gets the 134 back to correct level it starts the purge again. I am lost for ideas and would love some imput. im am realitivly competent with automotive mechanics and am not afraid to open her up. Help me so i dont catch fire on the way to the fire station for shift. Thanks again guys and gals. Be safe.

 

I can't say for sure what the problem is. I think you'd get more responses if you started a new thread with this problem.

 

ol'blue thanks for the PM , a little late, but thanks.

 

I have been told that my evaporator is leaking, is there any way to pressure check it before i go though this process? I have a 1999 Jeep Cherokee with a 4.0
