Chevrolet Uplander Front Wiper Motor Guide (2005-2009)
Having trouble with your Uplander's wipers? This guide explains common failures and how to choose the right replacement motor.
- Wiper failure symptoms like only working on high speed or not parking correctly are very common and point to a bad motor.
- Before replacing the motor, always check the fuse and listen for a humming sound; if it hums, the linkage might be the problem, not the motor.
- When replacing the motor, inspect the nearby engine wiring harness for any chafing or damage, as this is a known issue on these vans.
- A GM recall (15V609) was issued for replacement motors that could overheat; this highlights a potential safety concern.
Is Your Uplander's Wiper Motor Failing?
A bad wiper motor on the 2005-2009 Chevrolet Uplander often gives warning signs before it stops working completely. Recognizing these symptoms can help you fix the problem before you're caught in bad weather.
Common Failure Symptoms
- Wipers only work on high speed: If the low and intermittent settings stop working, it usually points to a problem with the motor's internal circuit board.
- Wipers won't 'park': When you turn the wipers off, they should return to the bottom of the windshield. If they stop in the middle of the glass, it's a classic sign of a bad park switch inside the motor.
- Slow or jerky movement: Wipers that move much slower than normal or seem to hesitate can be a sign of internal wear inside the motor.
- No movement at all: If you turn the wipers on and nothing happens, the motor has likely failed. You might hear a faint humming sound. Before replacing the motor, always check the fuse first.
- Humming or grinding noises: Strange sounds from the base of the windshield when the wipers are on can mean the motor is struggling or internal gears are stripped.
Known Issues for This Vehicle
For this generation of GM minivans, including the Uplander, two specific issues are worth noting:
- Pulse Board Failure: A very common problem is the failure of the internal circuit board (pulse board) that controls wiper speed and the park function. This can cause intermittent operation or make the wipers stop in the wrong place.
- Wiring Harness Chafing: The National Highway Traffic Safety Administration (NHTSA) investigated an issue where the wiper motor crank arm could rub against the main engine wiring harness. This could damage the wires and, in some cases, lead to stalling or a no-start condition. When replacing the motor, it's a good idea to inspect this harness for any signs of wear or damage.
Recall Information
In 2015, General Motors issued safety recall 15V609 for certain replacement windshield wiper motors that may have been installed during service on these vehicles. The defect could cause the motor to overheat, potentially leading to smoke or fire. The recall involved replacing the wiper motor cover. This did not apply to the original factory-installed motors but is important to be aware of if a previous owner replaced the motor.
Choosing the Right Aftermarket Wiper Motor
When your original wiper motor fails, you have several options. A new OEM (Original Equipment Manufacturer) part from a dealer is the most expensive. Aftermarket parts offer a more affordable solution. For the Uplander, brands like Cardone, WAI Global, and Replacement are common.
- Premium Aftermarket (e.g., Cardone): Cardone is a well-known brand that offers both new and remanufactured parts that are designed to meet original standards. They are often considered a good balance of quality and price.
- Standard Aftermarket (e.g., WAI Global, Replacement): These brands provide a functional, budget-friendly alternative. While they are built to fit and work like the original, some user reviews across various parts suggest that quality can sometimes be inconsistent compared to more established brands. For a critical safety component like a wiper motor, a higher-quality part is often worth the small extra cost.
Estimated Replacement Costs
The cost to replace a wiper motor depends on the type of part you choose and whether you do the job yourself or hire a professional.
| Part Type | Estimated Part Cost |
|---|---|
| New Aftermarket | $83.90 - $246.39 |
| Shop Labor | $60 - $140 |
Frequently Asked Questions (FAQ)
Is it hard to replace the wiper motor on a 2005-2009 Uplander?
No, it is a fairly straightforward job for a DIYer with basic tools. The main steps involve removing the wiper arms and the plastic cowl panel to access the motor. The most difficult part is often removing the wiper arms from their splines without a special puller tool.
My wipers work, but they stop in the middle of the windshield. Do I need a new motor?
Yes, this is a classic symptom of a failed 'park' switch, which is located inside the wiper motor assembly. The most reliable solution is to replace the entire motor.
Should I buy a new or remanufactured wiper motor?
Both can be good options. A quality remanufactured motor from a reputable brand like Cardone is rebuilt to meet original specifications and can be a cost-effective, reliable choice. A new aftermarket motor is also a good option, but it's wise to stick with known brands for better quality control.
I hear the motor running, but the wipers don't move. What's wrong?
If you can hear the motor humming but the wipers aren't moving, the problem is likely with the wiper linkage (also called the transmission), not the motor itself. The linkage arms have likely disconnected from the motor's crank arm.
