Lexus LX450 Windshield Washer Pump Guide (1996-1997)
Everything you need to know about diagnosing and replacing a faulty windshield washer pump on your LX450.
- A failed windshield washer pump is a common issue for the 1996-1997 LX450, but it is an easy and inexpensive part to replace.
- Symptoms include no spray, a weak spray, or no sound from the pump when activated.
- Before replacing the pump, check the fluid level, fuse, and for clogged nozzles.
- An aftermarket Trico pump is a cost-effective alternative to the more expensive OEM part.
Is Your Windshield Washer Pump Failing?
A non-working windshield washer system on your LX450 is often due to a failed pump. Over time, the small electric motor inside the pump can wear out or burn out. If you activate the washers and hear nothing, or just a faint hum without any fluid spraying, the pump is the most likely culprit. Before replacing the pump, it's wise to check a few simple things first. Make sure your washer fluid reservoir is full. Also, check the fuse for the washer system to ensure it hasn't blown. Occasionally, the spray nozzles on the hood can become clogged with wax or debris, which you can clear with a small pin.
Check the Diverter Valve
The 1996-1997 LX450 uses a diverter valve to send washer fluid to the front or rear windows. These valves can fail and cause a weak stream or leak fluid intended for the front to go to the rear. If you're replacing the pump, it's a good time to inspect this valve as well.
Choosing an Aftermarket vs. OEM Pump
When it's time for a replacement, you have two main choices: a new Original Equipment Manufacturer (OEM) pump from Lexus/Toyota or a new aftermarket pump. OEM pumps are identical to the part your vehicle came with, but they come at a higher price. Aftermarket parts, like those from Trico, are designed to meet or exceed OEM specifications at a much lower cost. For a straightforward part like a washer pump on the LX450, an aftermarket unit is a reliable and budget-friendly choice. Many owners have successfully used aftermarket or equivalent Toyota pumps with no issues.
Easy Installation
Replacing the washer pump on the LX450 is a job most owners can do themselves in under an hour. The pump is located on the bottom of the washer fluid reservoir, which is accessed by removing part of the passenger-side front wheel well liner. The pump itself simply pulls out of a rubber grommet. No special tools are required.

Frequently Asked Questions
Why is my washer fluid not spraying, but I can hear the pump?
If you can hear the pump motor running, the pump itself is likely working. The problem is probably a blockage somewhere else. Check for clogged nozzles on the hood, or disconnected or pinched fluid lines. On the LX450, also consider a faulty diverter valve that might be sending fluid to the wrong place.
Is it difficult to replace the LX450 washer pump myself?
No, this is considered an easy DIY job for most people. Access is gained through the wheel well, and the pump just pulls out of the reservoir. The entire process can typically be completed in less than an hour with basic hand tools.
Are there any recalls for the 1996-1997 LX450 windshield washer pump?
No, there have been no safety recalls issued by the NHTSA for the windshield washer system on the 1996-1997 Lexus LX450.
Should I replace the rubber grommet with the pump?
Yes. A new aftermarket pump should come with a new rubber grommet. It is highly recommended to use the new grommet to ensure a tight, leak-free seal when you install the new pump into the reservoir.
