Parking light fuse keeps blowing 1996 Mazda b2300?

Answer 1

You need to pull the tail light covers off both sides and check the sockets for corrosion.If the area around the bulbs are black or melted u need to replace the sockets because they are grounding out(getting to hot and shorting the electrical system).Check the sockets and either clean or replace based on condition.To clean use electrical cleaner sold at most auto stores specifically for electrial components.Also use some white lithium grease around the bulb ends before installing to prevent corrosion and moisture build up over time. === === Fuses and Circuit Breakers are safety devices designed and installed in electrical circuits TO PROTECT the conductors [wires] from short circuits and overload conditions which can cause extreme overheating which can result in damage to the conductors, and worse, the possibility of a FIRE which could destroy the vehicle. When a fuse, and its replacements, repeatedly blow, is an indicator of an UNSAFE CONDITION[short or overload] in that circuit. To install a larger fuse would invite damage to the wiring and an electrical system fire. The proper "fix" is for a qualified technician, who knows what he/she's doing, to * troubleshoot the circuit, * find and identify the defect, and * make proper repair [s], BEFORE replacing the fuse again [with a properly sized fuse for the circuit].
