The Duke Posted October 12, 2018 Share Posted October 12, 2018 I have a 2011 Ford Fusion & this is what I'm experiencing. I removed the little trunk rectangular dome light to replace the factory bulb with a spare LED bulb that I had so it would be brighter. The domelight did arc some while removing it from part of the bulb connector touching the metal part of my car. The LED bulb stopped working. I put the factory bulb back in & it didn't light up. The 2 map lights in the front of my car only come on when I open the door or rotate the dimmer up. They wont turn on with the black push button. The rear map lights won't come on at all. I checked the #9 15 amp fuse & it was fine. Did I blow another fuse? Not sure what the issue is or if the LED bulbs aren't compatible with my car. I trie LED bulb in the front map light fixture. No such luck with them. Do I need a load resistor? 0 Quote Link to comment Share on other sites More sharing options...

So between that and touching the metal, you probably did cause a short and blow a fuse. I do not have the 2011 Fusion Owners Manual available at the moment. You need to check your Owners Manual fuse diagrams to if any other fuse positions (besides #9) may interact with the control the circuits for the non-operational accessories you mention. Also, just double check to be sure you actually changed the correct fuse in the correct box (sorry, we have seen this mistake made before). If I have the chance to download the Manual and check, I will post back with that information. EDIT - Just took a look at the 2011 Fuse Box diagram. Perhaps also check fuse #25 in the Passenger Compartment Box Keep us updated and good luck. Edited October 12, 2018 by bbf2530 0 Quote Link to comment Share on other sites More sharing options...

No such luck with them. Do I need a load resistor? Replace F25 (10A), that's the one for "demand lamps". No, you don't need load resistors when using LEDs on the interior lamps - they are only required for tail/brake/headlamp. 0 Quote Link to comment Share on other sites More sharing options...
bbf2530 Posted October 12, 2018 Share Posted October 12, 2018 Ooops, eGuru beat me to it. And thank you for the load resistor information eGuru. 0 Quote Link to comment Share on other sites More sharing options...
