My '05 just began exhibiting a problem that I can't find in the manuals or in my searches on TDR... My interior lights (reading lamps) won't light unless I turn the brightness riostat up to the "on" position (one click below the "Cargo Lamp" position). When there, I can turn the lights on & off (they used to remain on in that setting and not turn off) but it keeps the dash lights on the brightest setting. If the switch is in the normal driving mode, the lamps won't light at all. :confused:

The really strange thing is that my truck was parked for a week while my family and I were on a trip; when we got back to the airport last night the interior lights operated normally when we first got in the truck, but then after about 10-15 seconds they went back to no longer working. :mad:

Does anyone know what's causing this, or what I can do to fix it????
