One Mirror Does Not Operate In Up/Down Positions

(LEFT/RIGHT POSITIONS OPERATE NORMALLY)

1. If left mirror does not operate, place mirror select switch in left position. Using a test light, backprobe mirror control switch connected connector, between terminals "C" and "E". See MIRROR CONTROL SWITCH CONNECTOR TERMINALS  table under ONE MIRROR DOES NOT OPERATE IN UP/DOWN OR LEFT/RIGHT POSITION. Toggle mirror position switch to up position, and go to step 3).
2. If right mirror does not operate, place mirror select switch in right position. Using a test light, backprobe mirror control switch connected connector, between terminals "C" and "F". See MIRROR CONTROL SWITCH CONNECTOR TERMINALS  table under ONE MIRROR DOES NOT OPERATE IN UP/DOWN OR LEFT/RIGHT POSITION. Toggle mirror position switch to up position, and go to next step.
3. If test light does not come on, check mirror control switch connector. If connector is okay, replace mirror control switch. If test light comes on, backprobe suspect outside mirror connector between terminals "C" and "D". See OUTSIDE MIRROR CONNECTOR TERMINALS  table under ONE MIRROR DOES NOT OPERATE IN UP/DOWN OR LEFT/RIGHT POSITION. Toggle mirror position switch to up position. If test light comes on, go to step 5). If test light does not come on, check suspect outside mirror connector. If connector is okay, replace suspect outside mirror drive unit.
4. If test light does not come on, check for an open in Light Green wire (left mirror) or Purple/White wire (right mirror) circuit between mirror control switch connector and suspect outside mirror connector terminal "C". If circuit is okay, check for an open in circuit between mirror control switch connector terminal "C" (Yellow wire) and suspect outside mirror connector terminal "D". Refer to, under ONE MIRROR DOES NOT OPERATE IN UP/DOWN OR LEFT/RIGHT POSITION, OUTSIDE MIRROR CONNECTOR TERMINALS  table, and also refer to in this article, MIRROR CONTROL SWITCH CONNECTOR TERMINALS  table.
