service 4wd system jeep will not start
Check fluid in transfer case this switch is mounted on the transfer case housing.
Sooooo.... had "service 4wd system" alert and then one day my 2008 jeep gc 5.7 hemi wouldn't start. Took it in and it was a fuse that controls both. NOTE: FUSE WAS NOT FRIED! It just tested as having bad resistance. They replaced the fuse and the error for "service 4wd system" has been gone since and she starts everytime! CHECK RESISTANCE ON THE FUSE!!!!
