Is Your GMC Tracker Washer Pump Failing?
A non-working windshield washer can be a safety issue, especially in bad weather. For the 1989-1991 GMC Tracker, the washer pump is a simple part, but when it fails, you'll notice it immediately. Because the GMC Tracker is mechanically identical to the Geo Tracker and Suzuki Sidekick from the same era, parts and repair information are widely available.
Diagnosing the Problem
Before buying a new pump, run through these quick checks:
- Check the Fluid: Make sure the washer reservoir isn't empty.
- Listen for the Pump: Have a helper activate the washer switch while you listen near the reservoir. If you hear a humming sound but no fluid comes out, you might have clogged nozzles or a leak. If you hear nothing, the pump motor has likely failed or there's an electrical issue.
- Check the Fuse: A blown fuse can prevent the pump from getting power. Check the fuse box for the wiper or washer circuit.
- Look for Leaks: Check the hoses for cracks or disconnection, and inspect the reservoir itself for damage.
No Recalls or Bulletins Found
As of early 2026, there are no specific recalls or Technical Service Bulletins (TSBs) from NHTSA for the windshield washer pump on the 1989-1991 GMC Tracker.
Choosing the Right Aftermarket Pump
Original Equipment (OEM) pumps for a vehicle of this age are likely discontinued and difficult to find. Fortunately, aftermarket pumps are an affordable and reliable solution. Brands like Trico offer direct-fit replacement pumps that are designed for easy installation without modification. Given the simplicity of the part, a quality aftermarket pump is a practical choice for nearly all owners.
Pro Tip: Check for Front and Rear Pumps
Some Tracker models equipped with a rear wiper may have a second washer pump. Confirm whether you are replacing the front or rear pump before ordering, as they can be different parts.

Frequently Asked Questions
Where is the washer pump located on a 1989-1991 GMC Tracker?
The windshield washer pump is located at the bottom of the washer fluid reservoir. It is pushed into a rubber grommet on the tank. You can usually find the reservoir, a semi-transparent plastic tank with a blue or black cap, under the hood on the passenger side.
Is replacing the washer pump a difficult job?
No, this is considered an easy DIY job that requires basic tools and about 15-30 minutes. The process involves siphoning out any remaining fluid, accessing the pump, unplugging the electrical connector, pulling off the hose, and popping the old pump out. Installation is the reverse of removal.
How do I know if it's the pump and not just a clog?
If you can hear the pump motor running when you activate the switch, but little or no fluid comes out, the problem is likely a clog in the lines or nozzles, or a leak. If you hear nothing at all, and the fuse is good, the pump motor itself has likely failed.
Is an aftermarket washer pump good enough for my Tracker?
Yes. For a straightforward part like this on an older vehicle, a quality aftermarket pump from a known brand is a cost-effective and reliable choice. Many are designed as direct OE replacements, ensuring proper fit and function.
