Toyota MR2 Window Motor Guide: 1985-1995 Models (AW11 & SW20)
Is your MR2's window slow, noisy, or stuck? Here’s what you need to know before buying a new motor.
- First, confirm if you have an AW11 (1985-89) or SW20 (1990-95), as the parts are different.
- Always test the window switch and wiring before condemning the motor; it's a common point of failure.
- For AW11 models, the problem is often a cheap, replaceable plastic gear inside the motor, not the entire unit.
- New aftermarket motors from brands like Dorman or Cardone Select offer a good balance of cost and quality for a DIY repair.
Is Your MR2 an AW11 or SW20? It Matters.
Before you shop, know your MR2. The 1985-1995 timeframe covers two different generations, and the window motors are not interchangeable.
- AW11 (1985-1989): Known for a specific failure where a small plastic gear inside the motor strips its teeth. Often, the motor itself is fine, but this one gear fails, causing clicking noises or intermittent operation.
- SW20 (1990-1995): While the motor can fail, issues with the regulator assembly, such as broken mounting tabs, are also common. The failure is less likely to be the small, replaceable gear seen in the AW11.
Symptoms of a Failing Window Motor
Watch for these common signs. How the window fails can tell you a lot about the problem.
- Slow Window Travel: If the window moves up and down much slower than it used to, the motor is likely getting weak.
- Intermittent Stopping: The window stops while moving, but starts again on its own after a pause. This often points to a stripped motor gear in AW11 models.
- Grinding or Clicking Noises: A repetitive clicking or grinding sound from inside the door panel during operation is a classic sign of stripped gear teeth.
- Window is Stuck: The window won’t move at all, but you hear a click from the switch. If you don't hear any sound from the motor, test the switch first.
- Needs a Helping Hand: If the window stops and you have to pull or push it to get it moving again, this may indicate a problem with the larger regulator gear, which is a more serious issue.
Warning: It Might Be Your Switch!
Many MR2 owners replace their window motor only to find the problem was a faulty window switch. The contacts inside the switch get dirty or worn over time. Before buying a motor, try testing the motor directly with a 12-volt power source to confirm it has failed.

New OEM motors for these cars are expensive and very hard to find. Aftermarket is the most common choice. Here’s a breakdown of the brands you’ll find.
- Good (Value Tier): Remanufactured Cardone (A1 Cardone)
These are original units that have been rebuilt. They are the most budget-friendly option. However, quality can be inconsistent, with some owners reporting issues with the remanufacturing process. They are a viable choice if budget is the primary concern. - Better (Standard Tier): New Aftermarket (Cardone Select, Dorman, Surtrak)
These are brand-new parts designed to fit your MR2. Brands like Dorman and Cardone's 'Select' line offer a good balance of price and reliability. They meet original specifications and are a popular choice for DIY repairs. While Surtrak is listed by some vendors, they are less known for window motors. - Best (Premium Tier): Used OEM
For a vintage car like the MR2, a good, tested used OEM motor can sometimes be the best choice for fit and longevity. The original motors are robust, and the main failure point (the AW11 gear) can be replaced. This option depends on availability from specialty recyclers.
| Part Type | Typical Price Range |
|---|---|
| New Aftermarket | $51.95 - $88.21 |
| Remanufactured | $50 - $70 |
| Used OEM | $75 - $150 (for assembly) |
| Shop Labor | $120 - $200 |
Pro Tip for AW11 Owners: Check the Gear First!
If you have a 1985-1989 MR2, you may only need to replace the small plastic motor gear, not the entire motor. These gears are available from specialty MR2 parts suppliers and cost much less than a whole new motor. The repair still requires removing the motor from the door, but it's a very common and cost-effective fix.

Can I replace just the window motor without the regulator?
Yes. The window motor can be unbolted from the regulator assembly from inside the door. It is held on by three bolts, which are sometimes Torx screws. This allows you to replace only the failed component, saving money.
Are there any recalls on the 1985-1995 MR2 window motor?
No. Searches of the National Highway Traffic Safety Administration (NHTSA) database show no recalls for the window motor or regulator on 1985-1995 Toyota MR2 models. Major Toyota recalls for window *switches* in the 2000s do not apply to these vehicles.
How can I tell if it's the motor or the switch that's bad?
A simple way to check is to bypass the switch. After removing the door panel, unplug the motor and connect it directly to a 12V battery. If the motor runs, your problem is likely the switch or wiring. If the motor does not run, it has failed.
Is the passenger side motor the same as the driver side?
No, they are not the same. Window motors are side-specific (left and right) because they are designed to turn in opposite directions to raise or lower the window. You must order the correct motor for the side of the vehicle you are repairing.
