    Fuse for Side Markers

    Hello again all... I am troubleshooting lights on my 2006 STS, and my side markers are not working. To be more specific, the front and rear turn signals are working, but the bumper mounted marker & fender side markers are not working. I replaced the bulbs today thinking this was the problem to no avail. So i looked through the owners manual to find the corresponding fuse, once again to be baffled. Can anyone please direct me to the correct fuse for these, and its location (under hood/under rear seat). thanks again all for this hopefully trivial problem.

    Re: Fuse for Side Markers

    There are actually two fuses for the side marker lamps. One is "LT PARK" for the left side, and the other is "RT PARK" for the right. Each is 10A and both are located in the under hood fuse block. If all four lamps went out at once, I'd be more suspicious of the park lamp relay, also in the under hood fuse block.
