Is Your Bronco II's Washer Pump Failing?
A failing windshield washer pump on a Ford Bronco II is a common issue due to the age of the vehicle. The symptoms are usually obvious. Before you buy a new part, make sure the problem isn't something simpler. First, check the washer fluid level. Next, check the fuse for the washer system. If the fuse is good and you hear the pump motor whirring when you hit the switch but no fluid comes out, the pump's internal filter may be clogged with slime from old fluid. If you hear nothing at all, the pump motor has likely failed.
Pro Tip: Check for Clogs and Leaks
The plastic and rubber parts on these older trucks can become brittle. While you're working on the pump, inspect the washer fluid hoses for cracks or breaks. Also, use a small pin or needle to clear any debris from the washer nozzles on the hood. 🎬 Watch: How to clean and aim your washer nozzles Sometimes a clog is the only problem.

Frequently Asked Questions (FAQ)
How hard is it to replace the washer pump on a Bronco II?
It is a very easy job that most DIYers can do in under 30 minutes with basic tools. The pump is located on the washer fluid reservoir. You simply unbolt the reservoir, unplug the electrical connector, pry off a small retaining clip, and pull the old pump out. The new pump presses into place.
🎬 See this walkthrough on how to replace the pumpDo I need to drain the washer fluid to replace the pump?
Yes. The pump sits at the bottom of the reservoir, so you will need to drain the fluid before removing it, or it will spill out. This is a good opportunity to clean any sediment from the bottom of the tank.
My pump makes noise but no fluid sprays. Is it broken?
Not necessarily. If the pump motor runs, the electrical part is working. The problem is likely a blockage. It could be a clogged filter screen at the pump's inlet, clogged washer nozzles on the hood, or a cracked or disconnected hose.
What is the most common reason for the pump to fail?
The most common failure is the electric motor burning out from age or from being run frequently while the reservoir is empty. The second most common issue is the pump's inlet filter getting clogged with gelled or contaminated washer fluid.
