There should be battery voltage.
a It the.e is no voltage, check for an open in the
BLK/YEL wire between the under-d8sh Juse/
felay box and the detogger switch.
a lf there is bsttery voltage, go to step 2.
2. Connect the BLK/YEL terminal of the 2-p connector
to the ORN terminal with a jumper wire.
Both the right and left mirro.s should g.adually
warm up with the ignition switch ON.
a It neither waJms up, repair the ORN wire.
