Jeep A/C problems

[pcn1]

My WJ A/C system is struggling to delivery air at 10 oC to the cabin vents. The mobile ac guy has emptied and refilled the system with new gas, says there are no obvious leaks, but he suspects the compressor is a bit "tired" as it took a long time to put the new gas back into the system.

Any of you WJ owners having air con problems yet ?

He also re-gassed my 15 year old Audi cab as that lost al its gas over winter storage, and that is delivering 5 oC !!!

cheers

Is the clutch on the compressor functioning correctly? Think you can lock it so you can see if the system works as it shhould, need to do it on mine

Well it engages to start the AC working, but do you mean they can slip or something ?
Is there a procedure to "lock" it in ?

from reading on the US forums you put a washer in behind the pulley wheel which packs out the clutch so it is always engaged. Not done it myself yet but is on the list of jobs to do

Pull out the thermometer & check line temps on high & low pressure side. should be hot & cold on high & low pressure lines respectively.
Easiest thing to check then
Check your evaporator & condensers, Clean them out if dirty.

Otherwise get trusted professionals in to fix it

Quick update. Seems I may have issue's with the blend doors not closing fully.
I've got 4.5oC cooling at the vents on start up, but when the engine starts to warm I've only got 11oC at the vents. Guy from the US forums told me to check that out. I put in new doors a couple of years ago so need to open up and check.
