So I've been attempting to solve the miscellaneous gremlins associated with my 94 ZJ (5.2MPI) and have had some intermittent success, however I have been really frustrated with the same old "coolant sensor" and "4wd switch" issues. I did replace "a" coolant sensor (right behind the alternator) and seemed to have a short period of success with that until the VIC alert returned to torment me. I also have the "constant chime" problem that I can't seem to rid the jeep of. I figured that maybe when I had resolved both issues the constant chime would stop, however that seems to not be the case. After researching JF pretty thoroughly I've come to the conclusion that it has to be a cracked solder somewhere within the VIC back panel (pin#5). I know this has been revisited time and time again, however I merely and respectfully was wondering if this is indeed the solution to all three of these issues.
On a seperate note, I also am seeing a "Open CKT" alert on the VIC when I perform the "holding the set and select buttons while turning ignition on". Is this further indication of a solder issue or circuit problem within the ZJ's sensor system?
Thanks for any and all insight!
