I have a 2008 F150 the power mirrors, power locks, key pad, remote entry don't work. The radio and dome light will come on by them self and run the battery down and don't shut off when the door opens, the TPMS and brake light stay on Ford told me it sounded like the GEM. I'm willing to have this GEM replaced for the 800.00 but just wondering if there could be something else wrong. I know my Ford dealer will tell me that something else was also wrong if the GEM don't fix the problem
