I have been getting an "external light out" signal on the dash for a while. Took it to the shop and they said it was a loose bulb and fixed it. However, about 3-4 weeks later it came back. I have searched and searched but cannot find a light out.
Then yesterday I got a letter stating that my Footwell Module may be bad and that it controls some light functions. Can a bad FRM cause a false "exterior Light out" signal?
