Jeep TJ Air Conditioning.
 

Hi:

I have a 1998 Jeep TJ Sahara, automatic with air - just encountered a
problem with the air conditioning - when any of the selections that
use air are selected on the slider, you can hear the air conditioning
unit engage for about 3 seconds and then promptly shut off, recycle to
another non-air setting and then back to an air setting and exactly
the same thing occurs - engages for about 3 seconds and then promptly
shuts off.

Went to the dealer - they want $150 just to get started on it - went
to a small shop - he wants $150 just to get started on it. They say
they charge it up, and use a dye to look for leaks - anybody
encountered this problem and what was the fix?? Where was it leaking??

Also pulled and re-installed the relay in the box under the hood
(didn't put in a new one)(there's no way you can tell if its working
or not unless you buy a new one and put it in??)- is there also some
sort of temperature sensor that might have gone that could be causing
the problem??

Anybody have any experience with this problem??

Thanks,

Jim Hawkins

Re: Jeep TJ Air Conditioning.
 

It's likely low on refrigerant. O-rings leak often. You can buy a complete
set of O-rings and replace them yourself, but you still have to get the old
refrigerant safely out and into a recycling unit, and the new refrigerant
back in. That is what the $150 is for. You can get by with a vacuum pump
like the one I bought two summers ago, but a good one will go for $500.
Heck a set of decent gauges will set you back $100. I should really have a
charging station, but with two vehicles that have air I just couldn't
justify the price.

For $150 you can't even get close to the equipment you need to fix this
thing yourself I vote for the small shop, especially if they have a good
local reputation.

Hi, When the clutch engages for a few seconds-you could be low on
134A. If you buy a charging kit,make sure there is no sealant with the
134A.It will clog the orfice tube. You will need a hose with
connectors,134A -1 can (without a sealer). Run the jeep -connect the
can to the hose-attach the cupping to the ac line.(only on size-can
not make a mistake). Once the clutch stays engaged and is blowing cold
air. You are done!
Good Luck.

Come on, Bill, where are you on this one? You are slacking off. We all
know that Real Jeeps don't have air conditioning.
