Chevy Trax Temperature Control Cable: how to identify, source, and fix the problem

If your Trax is stuck blowing hot air, the temperature knob has no effect, or the control feels loose, the likely culprit is the chevy trax temperature control cable. This small mechanical linkage is inexpensive, widely available, and — in many cases — straightforward to replace. In this guide I’ll explain how the cable works, the symptoms to watch for, OEM and aftermarket part options, what replacement entails, cost expectations, and whether you should tackle the repair yourself or go to a shop.

What the temperature control cable does (and why it matters)

The chevy trax temperature control cable connects the temperature selector on the dash to the blend/temperature door inside the HVAC housing. When you rotate the dash control, that motion is transmitted via the cable so the blend door mixes warm and cold air to the cabin. A cable that is stretched, broken, or has slipped its mounting will either fail to move the door or misalign it, leaving the system stuck on one temperature regardless of the knob position. Because the cable is the mechanical link in a typically electronic/airflow system, it’s a small part with a big effect on comfort. 

Common symptoms that point to cable failure

Owners and technicians report a consistent set of symptoms when the chevy trax temperature control cable goes bad:

• The temperature knob rotates but cabin temperature doesn’t change (or changes only slightly).

• The control feels loose or the knob clicks without resisting.

• The HVAC system is permanently on heat or permanently on cold regardless of the setting.

• Intermittent operation — sometimes the temperature responds, sometimes it does not.

These symptoms are commonly described in owner forums and troubleshooting videos for Trax and Sonic models, and they frequently lead to the temperature control cable as the first replacement part to try. 

Which Trax years and part numbers are affected

The chevy trax temperature control cable most commonly referenced in listings and guides fits model years roughly in the 2015–2021 range (the same cable is also listed for the closely related Chevrolet Sonic). GM and aftermarket parts use part numbers such as GM 95476706 and aftermarket references like Dorman 926-822 / 926-825 for equivalent applications. Checking the exact part number and vehicle compatibility is important before ordering, because there are small differences across years and trim levels. 

Where to buy — OEM vs aftermarket options

You can source a chevy trax temperature control cable from multiple channels:

• OEM GM parts dealers or OEM parts webstores that list GM part number 95476706 for specific fitments. OEM parts guarantee factory fit and finish. (core keyword use 5)

• Established aftermarket brands (Dorman and others) that sell direct replacement cables under part numbers like 926-822/926-825. These are often available through AutoZone, Walmart, Amazon, and eBay listings and can be significantly cheaper than dealer pricing. (core keyword use 6)

• Marketplace sellers offering generic replacement cables; prices vary considerably and listing quality can be inconsistent — verify compatibility and return policies before purchase.

Typical cost range and lead times

Expect the chevy trax temperature control cable to cost in the region of tens of dollars for an aftermarket part and potentially higher for OEM (prices will vary by vendor and location). Marketplace listings and big-box parts stores frequently list units in the $20–$100 range; labor to install (if you choose a shop) will add to that. For many owners this is an economical repair compared with replacing control modules or other HVAC components. 

The replacement — overview and difficulty

Replacement guides and demonstration videos show that replacing the chevy trax temperature control cable is often a DIY-friendly job for someone with basic tools and mechanical confidence:

• The dash center bezel and glove box may need partial removal to access the HVAC control panel and cable routing.

• Under-dash access to the cable end and inside the HVAC housing is required to unhook the old cable and connect the new one.

• Manufacturer guidance (see technical bulletin) highlights indexing the temperature valve gear and torquing the retaining screw to specification so the blend door and cable align properly. Following those steps avoids misalignment that would leave the system stuck. (core keyword use 9)

If you’re comfortable removing trim, watching a video walkthrough, and working under the dash, you can often complete the swap in 30–90 minutes. If the route is obscured by components or if you prefer certainty, a shop will do it faster and provide warranty work. 

Step-by-step checklist for a safe DIY swap

If you decide to replace the chevy trax temperature control cable yourself, follow this checklist:

1. Verify the exact part number for your model year before ordering.

2. Remove battery negative if you’ll be working near airbags/electronics for safety.

3. Remove dash bezel/glove box per a published guide or video relevant to your year.

4. Unhook the old cable from the dash control and from the blend door actuator; note any indexing marks.

5. Install the new cable and index the gear teeth per the technical bulletin instructions, and torque the retaining screw to the published spec.

6. Reassemble and test all HVAC positions on the knob — verify full sweep and correct temperature response.

Following the bulletin instructions for indexing and torque prevents misalignment that can make the repair appear to fail even when the cable is correctly installed. 

Pros and cons: DIY vs professional installation

DIY advantages for the chevy trax temperature control cable include lower parts-plus-labor cost and the ability to complete the repair quickly if you have the right tools. The downside is potential frustration if trim removal is unfamiliar or if alignment steps are missed. A professional installation provides warranty, avoids trim damage, and typically handles any unexpected complications (broken clips, seized screws) quickly. The part is common enough that most independent shops and dealers will be familiar with the repair. 

Maintenance tips and aftercare

Once the chevy trax temperature control cable is replaced, treat it gently during initial use to seat the cable and linkage: cycle the temperature control through its range several times to confirm smooth operation. Avoid forcing the knob if resistance is felt; recheck the installation and indexing if behavior seems off. Periodic cabin access checks are unnecessary — this cable is a low-maintenance mechanical part provided it’s correctly installed and not exposed to unusual impact or moisture.

Final recommendation and sourcing checklist

 Order from a reputable supplier with a returns policy, and if doing the work yourself, follow a recent video walkthrough plus the NHTSA/technical bulletin alignment instructions to ensure correct indexing and screw torque. When in doubt, a quick shop visit will save time and provide peace of mind.
