Is Your Windshield Washer Pump Failing?
When your Reatta's windshield washers stop working, the pump is a likely suspect. However, due to the age of the vehicle, it's wise to check a few things before buying a new part. Owners often find that other related parts are the source of the problem.
Check These First
- Clogged Hoses or Nozzles: Debris can block the lines or the small nozzles on the wiper arms. A forum member noted that blowing compressed air back through the lines can often clear them.
- Leaking Reservoir or Grommet: The plastic washer fluid reservoir can develop cracks over time. The rubber grommet that seals the pump to the tank is another common leak point. If you constantly have to refill the fluid, check for puddles under the car.
- Blown Fuse: Always check the fuse panel to ensure the pump is receiving power.
Choosing the Right Aftermarket Pump
For a classic car like the 1988-1991 Buick Reatta, original equipment (OEM) parts from GM are generally no longer in production. You might find a New Old Stock (NOS) part, but it will be rare and expensive. The most practical and common solution is a new aftermarket pump.
Trico is a widely available aftermarket brand that produces pumps compatible with the Reatta. Reviews for Trico pumps are generally positive, with owners of classic GM vehicles noting they are easy to install and work well. They are often described as a dependable and straightforward fix. Other brands like ACDelco (GM's service part line) also offer compatible pumps.
Installation Tips for the Buick Reatta
Replacing the washer pump on a Reatta is a job most DIY mechanics can handle. Unlike many cars that require removing a fender liner, access on the Reatta is from the top of the engine bay.
Reatta-Specific Installation Step
According to Reatta owners, to access the washer fluid reservoir and pump, you must first move the relay center out of the way. This is done by removing its lid and unscrewing two Torx (T15) screws. Once the relay center is moved aside, you can reach the reservoir's mounting screws and remove the assembly to swap the pump.

Frequently Asked Questions
Are there any recalls for the Buick Reatta windshield washer pump?
No. There have been no recalls or technical service bulletins (TSBs) issued by the NHTSA or GM for the windshield washer pump on the 1988-1991 Buick Reatta.
How hard is it to replace the washer pump myself?
It is considered an easy DIY job. The key vehicle-specific step is moving the relay center to access the reservoir. The pump itself simply pushes into a grommet on the tank and is held by friction. The total time is typically under one hour.
Should I buy an OEM or aftermarket pump?
Aftermarket is the standard and most realistic choice. New OEM pumps are likely unavailable unless you find expensive New Old Stock (NOS). Aftermarket brands like Trico offer a reliable and affordable replacement that is readily available.
My pump runs, but no fluid comes out. Is the pump bad?
Not necessarily. If you can hear the pump motor whirring, the electrical side is working. The problem is likely a blockage in the system, an empty fluid reservoir, or a leak from a cracked tank or bad grommet. It could also be that the pump's internal impeller has failed, but checking for clogs and leaks first is recommended.
