The 1967 Chevrolet Impala, Caprice, and Impala SS are among the most stylish full-size cars Chevrolet ever produced. While most attention goes to the exterior design and big-block performance, the interior details—especially the 1967 Chevy Impala Caprice SS A/C Heater Unit Dash Controls—play a major role in both comfort and the overall quality of a restoration.
These dash controls operate the heater, defroster, and air conditioning system (on A/C-equipped cars). Over time, the original control assemblies frequently wear out, become difficult to operate, or suffer from broken knobs, faded faces, and damaged cables. Replacing or restoring them is an important step in bringing a 1967 full-size Chevy interior back to proper working condition and appearance.
In this guide, we’ll cover how these controls work, common problems, what to look for when buying replacements, and helpful restoration tips.
Understanding the 1967 Impala, Caprice & SS Climate Controls
In 1967, full-size Chevrolets used a cable-operated climate control system mounted in the dash. The 1967 Impala A/C heater controls (and matching Caprice/SS units) allowed the driver to manage:
- Airflow direction (defrost, floor, dash vents)
- Temperature blend
- Fan speed
- A/C engagement on air-conditioned cars
The control panel was designed to integrate cleanly with the rest of the dash, featuring period-correct lettering, knobs, and a functional layout that matched the upscale interior styling of the Caprice and the sportier SS models.
Common Problems with Original Dash Controls
After more than 55 years, original 1967 Caprice dash controls and Impala/SS units often develop several issues:
- Stiff or seized control levers
- Broken or stretched control cables
- Missing or damaged knobs
- Faded or unreadable control faces
- Cracked plastic housings
- Poor electrical contact on blower switch
These problems not only hurt the appearance of the dash but can also make the heating and A/C system difficult or impossible to operate correctly. Replacing the control unit (or rebuilding it) restores both function and a clean, factory-correct look.
What to Look for When Buying 1967 A/C Heater Unit Dash Controls
When shopping for 1967 Impala SS heater control unit replacements or Caprice versions, consider the following:
- Correct Application – Confirm the controls are specifically for 1967 full-size Chevrolet models (Impala, Caprice, SS).
- A/C vs. Non-A/C – A/C-equipped cars use a slightly different control assembly than heater-only cars.
- Completeness – Some units come as a full assembly, while others may require you to reuse cables or knobs.
- Quality of Reproduction – Look for clear lettering, proper fitment, and durable materials.
- Condition (if used/NOS) – Original units should be inspected carefully for cracked housings and smooth lever movement.
A high-quality set of Chevy Impala Caprice A/C dash controls 1967 should fit the dash opening properly and operate smoothly once the cables are correctly adjusted.
Restoration and Installation Tips
Whether you’re installing a new reproduction unit or refurbishing an original, here are some helpful tips:
- Take clear photos of the original cable routing before removal.
- Label each cable as you disconnect it.
- Inspect and replace worn control cables if needed.
- Test the blower switch and electrical connections.
- Install the new or restored control unit and adjust cable tension for smooth operation.
- Reinstall knobs and verify all functions (heat, defrost, A/C, fan speeds).
Taking your time with cable adjustment is especially important—poorly adjusted cables are one of the main reasons climate controls feel stiff or don’t move fully through their range.
Final Thoughts
The 1967 Chevy Impala Caprice SS A/C Heater Unit Dash Controls may seem like a small detail, but they have a big impact on both the usability and the finished appearance of the interior. Fresh, properly working controls make the cabin more comfortable and help complete a high-quality restoration.
Whether you’re finishing a show-level Caprice, refreshing a solid Impala driver, or restoring an SS, upgrading or replacing the dash climate controls is a worthwhile investment that you’ll notice every time you drive the car.
Frequently Asked Questions (FAQ)
Do the same controls fit Impala, Caprice, and SS models?
In most cases, yes. The basic control units for 1967 full-size Chevrolets are very similar, but always confirm whether the car is A/C-equipped or heater-only.
What’s the difference between A/C and non-A/C controls?
A/C-equipped cars have additional functions and a slightly different control face and lever arrangement compared to heater-only vehicles.
Are reproduction dash controls available?
Yes. Quality reproduction 1967 full-size Chevy heater control panels are available, along with used and NOS originals.
How hard is it to replace the dash controls?
Moderate. The job requires working under the dash and carefully handling control cables. Patience with cable adjustment is key.
Can I just replace the knobs instead of the whole unit?
Sometimes. If the main control assembly is still in good working condition, new knobs and a cleaned face can improve the appearance significantly.
Why are my controls stiff or hard to move?
This is usually caused by worn, corroded, or poorly adjusted control cables, or by a lack of lubrication in the mechanism.
Should I replace the control cables at the same time?
It’s often a good idea, especially if the original cables are stiff, frayed, or stretched.
Will new controls improve the look of my dash?
Yes. Clear lettering, proper knobs, and smooth operation make a noticeable difference in the overall interior presentation.
