Have Toyota Questions? Ask a Mechanic for Answers ASAP
The dashboard lights work. No other lights on the interior work. The fuse is fuse number 7 in the engine compartment.
I need to leave for a meeting in about 5 minutes. Please respond to my email: [email protected]
Thank you for your help.
I do not have the original fuse. I checked the owner's manual and it identifies fuse position #7 as "Dome" and the circuit includes "personal/interior lights, vanity lights, door courtesy lights, luggage compartment light, engine switch light, trip information display". None of these lights work except the trip information display does work. The trip information display has continued to be lite without any problem even if the other lights are no longer working. The manual says the fuse size is 10A so I was wrong when I said the original fuse was a 5 amp fuse. The fuses that I have installed are BUSS brand fuses...ATM-10.
When the fuse has been replaced, it hasn't blown immediately. The lights have worked for 2-4 days and then all of a sudden they no longer work.
All of the work has been done at the Toyota dealership shop. They told me that they checked all bulbs and they were okay except for one that was replaced.
How many miles on this vehicle?
How will I receive other experts input? I can't leave my computer on this site indefinitely and you indicated earlier that you could not respond to my personal email.
I understand and agree with you that diagnosis in person is the logical way, but I was hoping for ideas for the mechanic to check (eg. replace all bulbs). Since they have already checked the bulbs on previous attempts to fix the problem, I would like to have other options for them to try.
Would appreciate receiving some ideas that I can offer the Toyota mechanic as things to check beyond what he has already done...he has replaced the fuse on three different occasions, checked the various switches, checked the bulbs (did replace one the first time) and says that his meter(?) does not show any shorts in wiring.
