I have a 2004 F150. The truck has the factory tow package installed. I thought installing a Hopkins Brake Force controller would be easy..... HAHA!
My problem is that after completeing the installation following all of the instruction provided I've lost the function of the following:
*Speedometer and Tach - These do not go through the normal sweep when starting and do not work at all after start up.
*None of the other gauges on the panel work either (battery, gas, temp, etc)
*The radio stopped working
*the sun roof does not work
*the rear sliding window does not work
*the interirior lights do not work
All other items in the truck work fine.
I've looked at the fuses for the items in question and none of them are blown. Is there a relay that controls these items that may have went?
I have unplugged the controller while I try to get this fixed. Has anyone else had a similar experiance with this type of controller?
I'd like to thank everyone in advance who may be able to help me with this.

 

Is this a new body style 2004 or a 2004 Heritage ?

The gauges should not sweep when you start the truck.
- On a 2004 heritage, this is an indication of a low battery.

You looked at the fuses, but did you check them with a meter, while installed, on the pins on the back of the fuse.

Sounds like the accessory delay relay fuse is blown.

 

This is the new body. You are right I only pulled and looked at them. I did not put the meter on them. I'll do that today. Another question...
Is there a way to check the relay or just replace and keep as a spare if that's not the problem? Either way you've given me a place to start. Thank you.

 

1. Check resistance of the coil, should be 50 to 100 ohms.

2. Hook meter ( continuity or ohms ) to the Normally open contacts, should read infinity or as an open.

Hook Terminal #85 to +VDC and ground to terminal #86.
3. With meter as installed in test #2, the NO contacts should have continuity or low ohms ( < 50 ohms ).
