Mopar 4221463 Park Brake

There is a brake light switch that is underneath the dash and at the top of the assembly of the brake pedal. You can check to see if voltage is present in a wire between the battery and switch using a test light as part of troubleshooting. Sort out any circuit problems if there is no voltage and if there is, don't be depressed by these lights on your car. On the contrary, they could be due to a fault on your brake pedal. On release, there would be 1 or 2 volts appearing between this switch and any lamp in the brake system; then it needs to be replaced but you must make sure that you count how many volts is coming from your car battery while you are doing it. Now, push down on the pedal again and test for voltage again. If there's voltage, then it means that there could be some problem with your braking system like brakes or even bad wiring connections which will not allow enough current through leading to failure; whereas, in the case where voltage does not seem to change upon pressing down onto pedals till all are reached at their limits which denote an open circuit somewhere inside wiring-both situations will require replacing switches without fail. Before fitting new switch into position though, just remove old one first by unplugging its connector before removing this device itself before putting the new unit back right into the same location, and lastly adjust necessary lever arms accordingly thereby bringing them to proper position.
