Garage Door Opener Transmitter: Testing and Inspection

Turn on the spotlight.
^ If the spotlight comes on, the Homelink's power and ground circuits are OK. If the Homelink will not open the customer's garage door, check that the Homelink is programmed properly (see the owner's manual) or call Homelink at 800-355-3515.
^ If the spotlight does not come on, check for these problems:
- A blown No. 37 (7.5 A) fuse in the under-hood fuse/relay box.
- An open in the WHT/BLU wire between the passenger's under-dash fuse/relay box and spotlight.
- An open in the BLK wire between the spotlight and G401/G402.
