the battery was dead. i charged battery. now the power windows, radio, memory seat, instrument cluster do not work. i have checked the fuses under the IP the owner's manual directs to. all fuses are good. what do i do next?

 

hmm... it may be a loose wire or accessory relay. try pulling and re-seating the relays in the fuse box under the hood. also, try jiggling wires that go from that fuse box and the wires going to the fuse box under the dash. There may be a loose ground wire somewhere as well. It may also be contacts inside the ignition cylinder (keyhole to start the car) not turning on the accessory lines (or rather a switch that it turns).

What model is your 2003 Mercury?

 

you might just need to wait a while for them being on for so long cause i know my power windows ill let them down then wait with either engine runin or in the acc or on pos. to listen to the radio then my motor starts to act weak then ill turn it off for a while then its act right like it got too hot or somthing but my power seat and radio dont do any thing
