Mercury Cougar Window Crank Handle Guide: 1973-1980
Is your window crank handle spinning freely or broken? Here’s what you need to know to get your window working again.
- The most common failure is stripped splines inside the handle, causing it to spin without moving the window.
- Replacement is a very easy DIY job that takes minutes and requires either a special tool or a simple shop rag to remove the retaining clip.
- Motormite (Dorman) is a widely available and reliable aftermarket brand for this part.
- If a new handle still slips, the splines on the window regulator shaft are likely worn, and the regulator itself will need replacement.
Symptoms of a Failing Window Crank Handle
When a window crank handle fails on a classic car like the Mercury Cougar, the signs are usually obvious. Because the connection relies on small teeth, or splines, wear and tear over decades can cause problems.
- Handle Spins Freely: The most common issue is a stripped handle. You'll turn the crank, but the window won't move. This happens when the metal or plastic splines inside the handle wear down and no longer grip the regulator shaft.
- Handle is Loose or Wobbly: Before it fails completely, the handle might feel loose. This indicates that the splines are wearing out or the retaining clip is failing.
- Cracked or Broken Handle: After 40+ years, the original plastic and metal can become brittle. The handle itself can crack, or the knob you hold can break off, making it difficult or uncomfortable to use.
Check the Regulator Shaft First
Sometimes, the splines on the regulator shaft are the part that's worn down, not the handle. If you put a new handle on and it still slips, the window regulator itself likely needs replacement. Using tools like vice grips on a stripped shaft can damage it further, turning a simple repair into a more expensive one.
Choosing a New Aftermarket Window Crank Handle
For a vehicle from this era, finding new original equipment (OEM) parts is nearly impossible. The market is primarily composed of used original parts and new aftermarket reproductions. Aftermarket parts are widely available, affordable, and often the most practical choice.
Brand Spotlight: Motormite (Dorman)
Motormite is a brand under the Dorman "HELP!" product line, which specializes in creating replacements for common failure-prone parts. For a simple mechanical part like a window crank handle, Motormite is a reliable and cost-effective option. Customer reviews for similar Dorman handles are generally positive, noting they fit well and work as expected. Some Dorman replacement handles even feature upgraded metal components to prevent the original stripping issue from happening again.
Aftermarket handles may have a slightly different finish or shape than the originals. For a perfect match, it's a good idea to replace the handles in pairs (e.g., both front doors) so the interior looks uniform.

Frequently Asked Questions
How difficult is it to replace the window crank handle?
This is one of the easiest repairs you can do. It requires minimal tools and takes only a few minutes per handle. The difficulty is a 1 out of 5.
What tools do I need for the job?
The handle is held on by a small metal clip. While there is a special window crank removal tool, you can easily do the job without it. A simple shop rag or a pair of paper clips with hooked ends can be used to snag and remove the clip.
How do I remove the old handle?
Slide a shop rag between the handle and the door panel, and use a back-and-forth motion to catch the edge of the clip and pop it off. Once the clip is off, the handle pulls straight out. To install the new one, make sure the clip is seated in the new handle, align it on the shaft, and push it firmly until it clicks into place.
Are there any recalls or technical bulletins for this part?
No, there are no NHTSA recalls or Technical Service Bulletins (TSBs) for the manual window crank handle on the 1973-1980 Mercury Cougar. This is a simple mechanical part not considered a safety risk.
Will a handle from a Ford Torino or Mustang fit my Cougar?
Yes, very likely. During this period, Ford, Mercury, and Lincoln shared many interior parts across different models like the Torino, Mustang, and Bronco. Always check the part description for specific year and model compatibility, but interchangeability is common.
