Troubleshooting Hints

Before performing wiper system diagnosis, make the following checks.
^ Check the wiper/washer Mini Fuse for an open. If there is an open, check for a short to ground through CKT 143 and replace the fuse.
^ Check that all the system connectors are mated firmly.
^ Check for bent or corroded connectors and terminals.
^ Check for a broken or binding wiper arm transmission assembly.

If the washer does not operate, check that:
^ The washer reservoir is filled.
^ The hoses are correctly attached.
^ The hoses are not cut, kinked or pinched.
^ The nozzles are not clogged.
^ The connector seal at the washer pump is not damaged or missing.
