I have a 2004 F150 Screw lariat and all of a sudden my power drivers seat, power pedals and mirrors are not responding. My passenger power seat, moonroof and power rear slider work just fine. I checked the fuse box and it looks like these things would be under fuse # 3. The fuse was fine. Does anyone know what this could be?

Thanks, Nick

 

might be another fuse controlling those things. i really cant tell you.

get to work with a volt meter and see what you come up with.

 

Check fuse #109. Usually when more than one things aren’t working its fuse related. Even though fuse #3 is good the fuse inline before it might be bad. I just checked out the online manual and fuse #109 30A fuse is related to your problem (Power drivers seat and pedals). I dont have a wiring diagram but this could also be related to fuse #3 which has to do with your power mirrors. The power seat, moon roof, and slider are on separate circuits.

 

just went and replaced the # 109 fuse and that is not the problem.....anyone else? I really dont want to go and pay someone to "search" for this problem and charge me a forune for a "simple" fix.

 

So both fuse #3 and #109 are good? Have you checked to see if there is voltage at both ends of these fuses?

 

not quite sure how to do that......I know how to use a multimeter, just dont know where to check.

 

Pull the fuse out and check if there is voltage on one post with a Voltmeter

 

You could even leave the fuse in and put the one DVOM (volt meter) prong on a good ground and other prong on one side of the fuse then the other side of the fuse. If its a hot fuse you should have voltage on both sides of the fuse. There will be a small gap in the plastic where you could test the fuse (That is where you are putting the DVOM prong). If theres voltage on one side and none on the other the fuse is bad.

You may want to turn the ignition on a test every fuse. If you have a test light this would be a lot easier and quicker.

 

its the drivers seat module under seat mind just did the same thing

 

If it is the memory seat module then you are looking for part number: 2C7Z-14C708-BA (has an engineering number of 2C7T14C708AE)

 

Same thing happened to my 04. The wires came loose how it effects the mirrors is beyond me. I checked every fuse all were good. Scratched my head and remembered the power seat plugs in some where?

 

fix for this problem....
