I'm a new 2002 WJ (actually WG - Austrian made) owner having upgraded from an XJ. Just getting the new truck up to scratch. It needed the blend door repair, blower controller connector repair, new EVIC, and I still have a fuel pressure leak-down issue. Other than that, all good. I can offer assistance to anyone who needs advice on these repairs.
please see my post in the WJ forum regarding EVIC compass VAR (variance) setting - I can't access it.
