in what country is this truck. 25,950 GVW (sized)
the service manuals are by country, and VIN code
the dealer sells service manuals. buy one.
most trucks and cars, 99%
open the glove box
remove users guide
open index page
see the word FUSE or Relay.
most times the relay is near the fuse. can be.
Did you scan the OBD2 port for errors first. (we do it first)
the check fuses.
then hunt Relays if it has one at all.
if you read the lids it tells the names
in all these places

the manual also says some countries, there is no horn at all.
(the manual say where found)
clearly
or it has AIR Horn OPTION, listed in the manual too.
says too, under options steering wheel without horn option.
yeah.
my guess is , the fuse and relay are part of the Horn kits
I see them listed in the parts pages.
best is buy the book, or search for relays all over the truck
as the video shows.
You need to determine where the noise is coming from. Check your power steering fluid and make sure it is full. Remove your serpentine belt and see if the noise goes away, That will let you know if it is coming from the engine or an accessory or pulley bearing. If the noise goes away whith the belt removed, check the alternator bearing and pulley bearings. If the noise is still there whith the belt removed, that means it is either in the engine or transmission.
what car, year,maker ,model
power to switches are fuse blown.
on old cars.
then 2007 to 2010
there is no fuse the BCM body brain runs brake lamps direct
and a small voltage digital signal from the switch
totally differ ways on new cars
is this a trail lamp issue?
tell car and I will show you the brake schematic from the online
FSM book.
A mechanic's scan tool would lbe necessary to check all the modules. The problelm could be either in the wiring or the control modules. There is also the chance the dimmer switch could be turned off or defective. Or, the electrical part of the ignition switch could be problematic. Because of the possibilities, use of the scan tool would seem the route to go.
To check for a coolant leak with a radiator pressure tester, the engine does not have to be warm. In fact, it's safer to perform the test when the engine is cool to avoid the risk of burns.
Here are the general steps to perform a coolant pressure test:
Make sure the engine and the system is cool since hot coolant can burn, and that the cooling system has no pressure.
If the coolant level is low, add water or coolant to raise it.
Remove the radiator cap once the system is cool and depressurized.
Connect the pressure tester to the coolant reservoir or the radiator.
Pump the pressure tester to apply pressure to the cooling system without going over the system's psi number on the radiator cap, which the pressure tester's gauge measures.
If the pressure gauge drops quickly, there is a leak. The slower the gauge drops, the smaller the leak.
As for your Buick, it's possible that the intake manifold gasket is leaking coolant. This is a common problem in many GM vehicles, including Buicks34. The coolant can leak externally, or in some cases, it may leak internally, causing coolant to mix with the engine oil. Operating the engine with a coolant/oil mix can result in internal engine damage. If you suspect this is the case, it's recommended to get it checked and repaired by a professional mechanic.
some bolts on things like this are LHB
left and bolts.
righty tighty and leftly loosey fails.
best is get the service manual and check it out.
no shaft told, at all, photo work easy here.
good luck !!!
You give absolutely no clue what on!! All questions in Cars and Trucks category need full 'year make model'.
If it isn't a Car it needs 'make model (what it is)'..
All the above should be the first 3 words in all questions.
Then you have over 40,000 categories to choose from.
We can't guess from what you have written.

If the belt has fallen off there must be a problem. The don't just fall off of the car without assistance. With the belt off, check all of your pulleys to make sure they are turning properly. Then, get the manual for your vehicle and it will show you how to do this job :() Every car is different but all cars are the same generally and this is usually just a matter of putting the correct wrench into the tensioner to remove/apply tension and route the belt around everything in the proper direction.
There is usually a sticker in the engine compartment/hood area that shows the diagram of how the belt is routed.
Dodge use a system called a "Lost Spark Ignition". Basically each coil fires two spark plugs on two different cylinders at the same time every time. One firing for the ignition stroke and the during the exhaust stroke on the other cylinder. Simply, a spark fired every other stroke on every cylinder. That means it only needs 3 coil packs on a V6 engine.
Your firing Order is 1, 2, 3, 4, 5, 6. Cylinder numbers are set as Odds and Evens. Stand with the belts and pulleys nearest to you. The cylinders on the Left side are the Odd numbers and the cylinders on the Right side are the Even Numbers. The cylinder on the LEFT side nearest to you is number 1. The middle one is number 3 and the one furthest away is number 5. The cylinder on the RIGHT side nearest to you is number 2. The middle one is number 4 and the one furthest away is number 6.
If you find screws or a latching mechanism, use the appropriate tool to open the compartment. It might be a good idea to wear gloves during this process to avoid any injury from broken glass and make sure the replacement bulb is the correct type for your scale.
