There are many ways to go about fixing these. Your best bet is to use the search function on this site, the info is unlimited. Also a great site with a complete write up is WJJeeps.com - Jeep Grand Cherokee WJ 1999-2004
and JeepsUnlimited.com Forums - Powered by vBulletin
both of these sites have write ups. The jeeps unlimited write up is and addendum to the wjjeeps write up. All info is in here, prices, even what wrench size you'll need to use.
You could go the easy way and use heater treater, or the others like it, but then you lose the dual climate control.(maybe not an issue to you) In the end do it yourself, take time to not misplace anything and save hundreds of dollars. Then you can laugh every time you drive by the mechanic's garage.
