You need a Mobile Auto Electrician with a pro grade bi-directional scan tool computer. Pulling fuses won't fix it.

It has ABS so it has to be pressure bled from the caliper upwards. Sounds like you purchased the wrong part. Should be identical https://www.google.com/search?q=2003+Dodge+Durango+brake+booster+parts. .

This sounds like an oil pressure problem, The very first thing I would do is if it's almost due for an oil change do it now, if not replace the oil filter it actually has a diaphragm in it to keep the oil from leaking back into the engine when the engine is off causing the oil pump to have to fill the filter before lubricating the engine causing the lifters to rap and the connecting rods to knock, remember to add oil if you just change the filter. If the engine has a lot of miles you might want to consider an oil treatment like SLICK 50 it coats the friction surfaces and prevents wear. I hope this helps. Take care.

Possibly broken wires or burned fuse. Check wiring above accelerator pedal. Check engine control fuses. Also check wiring near injector pump and throttle--top of engine.

It is a malfunction in your climate control system

THE pcm RUNS LOTS OF EVAP tests top cause , gas cap loose 10000 : 1 common like SUN is hot. reset the DTC and drive. using scan tool for sure.

1. Loose fuel gap
2. Faulty fuel tank pressure sensor (almost never fails)
3. Faulty wiring for the fuel tank pressure sensor

i remove #4 and clean it and flush it with walmart silicon spray,this silicon magic is super super slippery and can last years. wd40 (old skool blue /yellow useless) use SILICON only. even a new cap first reset the code with scan tool,do not try to drive it off can take a month,(pain) reset it. if still fail, clean #4 the leak is real 99.% of the time. and cause big time simple. cap bad #4 valve hung up,. easy easy fix. all valves here can be fixed with silicon spray,. it means gas vapor vents leak. assume easy fix not hard labor on smoke machine. leave mr smoke to last chance garage act. and save a bundle.

there is an emissions sticker under your hood. that shows routing.

No, your brake lamps should only work when brake pedal is activated. Your headlamp switch shouldn't have anything to do with brake lites. Sometimes if there is a faulty ground, your lamps may act weird? Did I miss-understand your post?

do you have 2 key if so try the other one to check if defective chip in key

bad wire or conection better take it to the best elec guy you know or shop

Probably a bad shift solenoid. Garage charge $250-400 to test and repair.

Visit the on-line store, known as reliable-store, they have the repair manuals. I'm sure you will get the solution of your problem.

Check to see if the brake light switch under the dash at the brake pedal is bad before you go too much further.

Check exhaust manifold for leaks/bolts loose, check the heat shield under the truck to see if it is loose (pass side).

Might be in 4-wheel drive. If so, put it back in 2-wheel - you may get some lingering bucking, but it should go away. Try driving on a slippery patch of road until it does - in this case rain is your friend!
