My TravelNote/Homelink transsceiver mounted on driver side sunvisor started blinking red and I noticed unit was not working correctly, I pulled fuse in an attempt to reset unit, and it worked correctly for a while, then started blinking again. Any suggestions, other than replacing unit?

 

Check the voltage regulator to make sure that the proper voltage is being output. If that's ok, then it's probably an issue with the transceiver and it will need to be replaced.

Since resetting it seems to get it to work again, there's probably something else wrong, but it could have an intermittent fault internally in the control module. Definitely check all wires and such going to the unit for proper connection. If everything "looks" good, then it's probably a voltage problem or module problem.
