I just picked up a well preserved 2000 cherokee Laredo. PO was having issues with the “computer”. Basically the thing would just die on him and a replacement computer alleviated the problem......replaced it something like 5-7 times without looking for the root cause of the failure. He got sick of it and got himself a replacement ride. Now I’ve looked into it and apparently the drivers door wiring harness could be the culprit but all I find is “check the drivers door harness” without any insight as to what to look for, what wire, connector, plug, joint, etc could be the issue.

Anybody have any experience with these?
