Have you tried adjusted the dimmer switch??Some other things to check are your grounds and the charging system.The ground between the engine block and firewall/chassis is the ground for the interior & exterior lights so make sure its tight and corrosion free. The next thing you should do is conduct a full charging system test. Here’s how to do your own. Connect a digital volt meter to the battery terminals. A fully charged battery should read about 12.7-volts. Start the engine. The reading should jump to around 13.5 volts. Leave the engine running and turn the blower motor to HIGH. The reading should dip down and then rebound back to 13.5 or more volts. Leave the blower on and turn on the headlights. It’ll dip again and rebound. Then turn on the rear defroster grid. Next, sit and watch the meter for about 10 minutes with the engine running and all those accessories on full blast. If the voltage stays the same at 13.5 or higher, the charging system is fine. A weak alternator will start pulling the voltage down in small increments because it can’t keep up with the electrical drain.
The most common cause of the alternator not charging when the belt is wet, is the belt is glazed or not tight.
The only thing that comes to mind to cause the charge light to come on when braking is the engine is shifting and you are loosing a wiring connection or ground.

I'm not sure but I think that fuse is in the fuse box under the hood. If not it will be in the fuse panel in the driver's footwell above the Park Brake pedal.
Try this web page. The fuse is marked as "FRT WPR". A 25A fuse. NOTE Only replace fuses with one of the same Amp rating. Fuses are commonly colour coded so that should help make sure it's the correct one.

Some potential solutions:
EGR (Exhaust Gas Recirculation): You mentioned that you cleaned the EGR, but it's still showing as a fault. The EGR system recirculates exhaust gases back into the intake manifold to reduce emissions. If the EGR valve is malfunctioning or clogged, it can affect engine performance.
Here are some steps to consider:
Check for Vacuum Leaks: Inspect the vacuum lines connected to the EGR valve for leaks or cracks. A vacuum leak can disrupt EGR operation.
Test the EGR Valve: Use a vacuum pump to check if the EGR valve opens and closes properly. If it doesn't, consider replacing it.
Clean the Intake Manifold: Sometimes carbon buildup in the intake manifold can affect EGR flow. Clean the intake manifold thoroughly.
Thermostat: You've already replaced the thermostat, which is good. A faulty thermostat can cause overheating or poor engine performance. Make sure the new thermostat is functioning correctly.
System Voltage Low: This could be related to the charging system (alternator, battery, or wiring).
Here are some steps to troubleshoot:
Check Battery Voltage: Measure the battery voltage when the engine is off and when it's running. It should be around 12.6V when off and around 13.8-14.4V when running.
Inspect Alternator: Ensure the alternator is charging properly. If it's not, consider replacing it.
Check Grounds and Wiring: Loose or corroded connections can cause voltage issues. Inspect battery terminals, ground connections, and wiring.
Idle Issues: If the engine won't idle properly, consider the following:
Idle Air Control Valve (IACV): The IACV controls idle speed. Clean or replace it if necessary.
Throttle Body Cleaning: A dirty throttle body can affect idle quality. Clean it using throttle body cleaner.
Vacuum Leaks: Check for vacuum leaks around the intake manifold, hoses, and gaskets.
Timing Chain: The B12D1 engine uses a timing chain. However, if it's stretched or worn, it can cause issues like poor performance or stalling. Consider having the timing chain inspected and replaced if needed.
Remember that diagnosing engine issues can be complex, and it's often best to consult a professional mechanic or use diagnostic tools.
Tensioner pulleys are designed to be 'Self Adjusting'. These pulleys are on spring loaded arms so they automatically push against the belt keeping it tight. You use a socket or a spanner to swing the pulley arm back against this spring.
*Note* This is a powerful spring so BE CAREFUL when your working on it!
A lot of these tensioners have two small holes to help with installing a belt. When you swing the tensioner arm back these two holes line up with each other. You can then slide a hex key, or something similar, through both holes and it holds the arm back giving you space to get the belt on.
*Caution* When your ready to release the tensioner DO NOT just pull the hex key out!! With the socket or spanner you used to swing the tensioner arm back push the arm against the spring again, carefully pull the allen key out then Carefully release the pressure on the spring so the pulley sits correctly and tensions the belt.
check the abs system for relay and electrical problems
the clicking can be from a cycling relay and the head lights flickering from the power draw for the abs away from the head lights.
