The horn on my truck sounds terrible. I took both of them off and noticed one was clogged with mud and water, but nothing I try gets it out. What can I do?

 

If they're already off the truck, I would just get new ones. They're like $10 each.

 

Where can I get them for that price? The local junkyards around here charge way too much for parts.

 

While I'm at it, there are a few other electrical problems I'm having with my F150. For starters the power locks occasionally go crazy and the motor will start cycling the locks, but the locks themselves won't move.

Also the range on my keyless remote has gone to crap lately. Rather than replacing the battery, is there a different/better battery I should swap into the remote to get improved range?

Finally, the rear cabin light above the sliding window will randomly just not work. How do I go about taking it apart to replace the bulb, or could it be something else?

Oh, one more thing, I'd like to get some brighter headlights, but have no clue what to get. What's the difference between Halo projector headlights, HID headlights, etc? I just want something that is a helluva lot brighters than what I have now so I can actually see what's in front of me.

 

I just googled "replacement horns" and every site that I looked at had them for $10-20. They have better ones, but I don't really see the point.

 

As far as your power locks going crazy, I think there may be a recall or TSB on that. If I recall correctly, there was a windshield leak or something that would cause the windows and locks to act up. Click on the link up at the top of the screen that says Recalls and TSBs. That will take you to another site where you can search for your vehicle.
