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 terminal "C" Light Green wire, "D" body) and terminal "D" (Yellow wire). 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 "E" (Yellow wire) and "F" (Light Blue wire). 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" (Light Green wire) and "D" (Yellow wire). Toggle mirror position switch to up position. If test light does not come on, go to next step. If test light comes 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 open in left outside mirror Yellow wire circuit between mirror control switch connector terminal "D" and left outside mirror connector terminal "D". If Yellow wire circuit is okay, check for open in Light Green wire circuit between outside mirror connector terminal "C" and splice No. splice No. S501 ("D" Body). See WIRING DIAGRAMS  .
5. If test light does not come on, check open in right outside mirror Yellow wire circuit between mirror control switch connector terminal "E" and right outside mirror connector terminal "D". If Yellow wire circuit is okay, check for open in Light Green wire circuit between outside mirror connector terminal "C" and splice No. S307 ("D" Body). See WIRING DIAGRAMS  .
