Help - NEED TO REPLACE A/C EVAPORATOR

[mail906]

I would appreciate some help or the referral to existing information.

I own a 2000 Grand Cherokee and the AC evaporator leaks. I need to replace it, and I am forced to do it myself as the dealer has quoted me an arm-and-a-leg to do it. I am trying to save on a 4-digit repair estimate that my dealer gave me.

Can anyone provide me with a link or a reference to the manufacturer's instructions on how to go about it? Something online would be ideal.

Also any other advice / tips / ways of doing it would be appreciated.

I understand the concepts, so what I am really looking for is a sequence of what to do first, second, third, etc.

Thank you.

I just tore my dash apart a couple weeks ago to replace my Evaporator Core in my 94 ZJ, it's not as hard as it seems took me about 3 hours, the unfortunate thing is no one has the evaporator core for my jeep so I will be waiting awhile til I can find one.

Check this page out, it gives the instructions to tearing the dash and stuff apart..... http://wjjeeps.com/hvac_sub_assembly.htm

I just placed a new condenser in my 1999 Jeep. It is time consuming but you can do it in your garage. (provided you can charge the A/C). you basically have to disassemble the dash to the firewall to get air box out. While you are there replace the heater core. I would suggest you get a service book if you do not have one.

A factory service manual or this link has the best info.

And when you get ready to recharge it.
You will need a good vacume pump to pump it down first and say no to them wal mart death kits.

Wal Mart DEATH KITS

You cannot properly and safely recharge an air condition system with them.

The one side stop and go gauge does not tell you what your system is doing or is over charged or undercharged.
A overcharged or malfunction air condition system can reach over 500 lbs of pressure.
Enough to blow up that can or system and freeze you at first and the burn you or blind you and if any propane /butane in there blow and light you up.

The stop leak crap and who knows what kind of oil in the kits there will stop your system for sure.
Just like pouring super glue in it.
And some kits even contain freon with a butane mixer.
Good for a big blast.

If you are going to do it do it right and safe.
Here is what you need to start with.

In the older days you could just throw in a can and go.
But over the years just adding freon is getting harder to do.
Newer systems have to have the correct amount of freon down to the ounces.
Most will need pumped down and vacuumed down and the right and amount of oil and a set amount freon charge installed to get the air to cool right and the system to last.
If an air condition is low there is usually a leak that needs fixed and also a lose of lubricating oil from system.
Also air and moisture enters a low system
If you are going to try to do it get the proper type air condition gauge set with the low and high side gauges.
Hook up the gauges and get a reading with compressor running at idle and at 2000 rpm on the high and low side.
Post back pressure reading and we can help you.
