Cadillac CTS (2010-2019) Windshield Washer Pump Replacement Guide
Is your washer fluid not spraying? Here’s what you need to know before replacing the windshield washer pump on your 2010-2019 Cadillac CTS.
- Confirm the washer fluid is full and the fuse is good before ordering a new pump.
- The pump is located behind the fender liner; on the passenger side for 2010-2014 models and the driver side for 2014-2019 models.
- Choose a quality brand like ACDelco or Trico to ensure proper fit and avoid having to do the job a second time.
- The replacement is a manageable DIY task that requires removing the wheel and pulling back the fender liner for access.
Is Your Cadillac CTS Washer Pump Failing?
A non-working windshield washer can be frustrating and unsafe. Before you assume the pump is bad, check two simple things first: make sure the washer fluid reservoir isn't empty and check the washer pump fuse. If both are fine, the pump itself is the likely problem. Common symptoms include:
🎬 Watch this guide to troubleshoot your washer pump issues.- No Sound, No Spray: You press the washer button and hear nothing. This points to a dead pump or an electrical issue.
- Pump Hums, No Spray: You can hear the pump motor running, but no fluid comes out. This could mean the pump's internal impeller has failed, or there's a clog in the lines or nozzles.
- Weak or Uneven Spray: The fluid barely reaches the windshield or only sprays on one side. This often indicates a dying pump that can no longer create enough pressure. It can also be caused by clogged nozzles.
Check for Leaks First
Look for puddles of washer fluid under the front of your car, especially near the passenger's side wheel for 2010-2014 models or the driver's side for 2014-2019 models. The pump itself or the rubber grommet where it seals to the reservoir can crack and leak.
Choosing the Right Aftermarket Washer Pump
For your Cadillac CTS, you have a choice between OEM-quality parts and standard aftermarket replacements. Since the labor to access the pump is the biggest part of the job, choosing a quality part is important to avoid doing the work twice.
Brand Quality Tiers
- ACDelco: As General Motors' official parts brand, ACDelco is the closest you can get to the original factory part. Choosing an ACDelco pump ensures perfect fitment and performance identical to what your CTS had when it was new. Some parts may even be the exact same as those sold in a GM-branded box.
- Trico: Trico is a well-respected brand in the wiper and washer system industry. Their pumps are designed to meet or exceed original equipment specifications for fit and function, offering a reliable repair at a lower cost than the dealer part. They are a durable alternative for a cost-effective repair.
A Note on Fitment
Some CTS owners have reported issues with incorrect pump sizes from generic brands. To avoid this, always verify the part number and ensure the pump you order is listed as a direct fit for your specific year and trim. Models with and without headlight washers may use different pumps.

Frequently Asked Questions
Is there a recall on the washer pump for the 2010-2019 CTS?
No, there are no specific recalls for the windshield washer pump on these models. There was a recall for the 2014 CTS concerning the wiper *module*, which could cause the wipers to stop working, but it did not involve the pump.
Where is the washer pump located on my CTS?
The location differs slightly by generation. For the 2nd generation (2010-2014), the pump is located low on the washer fluid reservoir, behind the front passenger side wheel well liner. 🎬 See how to replace the pump on 2008-2014 models. For the 3rd generation (2014-2019), it is in a similar position but behind the driver's side wheel well liner.
🎬 Watch this 3rd Gen replacement without removing the fender.Can I replace the washer pump myself?
Yes, this is a DIY-friendly job for someone with basic tools. The process involves safely lifting the vehicle, removing the correct front wheel, removing some clips to pull back the plastic fender liner, and then swapping the pump. The pump itself is simply pressed into a rubber grommet on the reservoir.
What is that oily film on my windshield?
If you see an oily substance on the *inside* of your windshield near the rearview mirror, it may not be a washer system problem. A GM Technical Service Bulletin (TSB) notes that the gel pad in the rain/moisture sensor can sometimes leak a small amount of oil due to heat. This does not affect the sensor's performance.
