Question about 2004 Ford F150

2 Answers

2004 F150 5.4 no power except dome and head lights. I was out with the wife doing the M-15 garage sale event, stopped for 5 min, came back to my truck and I couldn't start it. No noises when the key is on, no dash, no radio, no windows or power locks, only the dome light, head lights, and the odometer will show when I open the door. My alternator had a crack in it, so I replaced that. My buddy said his went bad on him and caused the same issue. Battery checked out fine, tested the new alternator, that tested fine. Had a lock smith come out and he said it wasn't the anti theft like some of the other forums have suggested. Any help trying to figure out where my issue is? I've pulled all the fuses and swapped the relays around, but still no luck. Noob question but, where is the power supply to the fuse box on this truck. Nothing is standing out to me. Could this grounding wire be the issue? Thank you everyone in advance.

SOURCE: 2008 jeep wrangler, no power to ignition or accessories, after replacing starter.

Take it to a shop. U fu--ed up royally doing the swap. If you had done the job correctly you would not be having this problem. Decent thing to do at this juncture is help your buddy pay for the correct repairs.

Testimonial: "That thought has been going through my mind since it all began. Problem is, I can't for the life of me figure out what I might have done wrong. Battery was disconnected before even getting under it to remove the starter, all connections were kept restrained to avoid anything making contact while doing the job. Everything was put back together tight and clean before reconnecting the battery. I didn't do anything different from any of the other jeeps I've replaced starters on in the past, yet I've never had any problems before. Please note, I'm not disagreeing with your assessment, just trying to get some insight on what I may have done wrong...."

No tail lights, no dash lights, no dome light, on 2006 Chevrolet Equinox

First, why not taking it back, you paid for nothing, this is not right, they should give your money back.
Check the fuse again, to see what is happening. Do you have lights at the front?

Security light does not come on but will not start tried the 10 minute with ignition on still nothing. radio,locks & dome light still work & buzzer when door is opened bings.

If it was a security program problem the security light should flash. The 10 min thing is correct, except you have to turn the key enough to turn the starer for a second and then leave the key on in the run position without turning it off for 10 min. You may have to do this three times to program. Make sure you turn the key all the way off for about 15 sec in between each cycle though. It could be a bad passlock sensor also. Do you have any after market remote start or security systems on the vehicle? that could cause the problem also, if it is a security thing.

Driver window problem?

Does the window work about half way the stops and if you wait a few min. does the window start working again ? If so it is most likely the window mtr. Another easy ck is to turn the key on without the engine running and operate the drivers window and watch the dome light .If the dome light dims with each direction of the switch then it is most likely the window motor (do this in the garage or at night easier to see the dome light.) If the dome light dims in only one direction than most likely the window switch . The best way is to take the door panel off and disconnect the window motor and connect a test light across the wires and operate the window switch. The test light will light in both directions if the wiring and the switch are good. Then replace the motor. If the test lights in only one direction (up or down ) then you will nee to ck the switch or wiring.

The oil light intermittently comes on

Common sighs of a faulty oil pressure sending unit. You can pic one up at Auto Zone for less then the dealer and they will have the step by step instructions for you to get the job done with common tools. Or you can take it to a local garage, and have them install the new oil pressure sending unit the same time you service the oil and filter. It takes an extra 15 min to install, so check with the garage on how much they will charge you. Most of the time you can tip the tech an extra $10.00 to install it for you and you keep your hands clean. Good luck and keep me posted.
