Used grade "A" headlight door actuator for your Mercury Cougar. Every once in a while we will get a car in that will have good original actuators. These actuators are sold individually on an exchange basis or outright (for an additional core charge). One actuator actuates both headlight doors. This unit also comes with a 90 day warranty.
Ford part # C9WY-13A167-A.
*NOTE* These actuators are prone to failure in two different areas. First is the small circular upper shaft seal. Often the reason this seal fails is that the "accordion" style dust boot that covers the shaft will fail. This causes contaminants to enter and work as an abrasive between the shaft and seal. When the shaft seal goes bad, you will find your headlights not raising very fast or not at all. If you continue to run your Cougar with this problem you are running with a constant vacuum leak. If you are puzzled as to why your 1967-68 Cougar does not idle well, lacks performance, and or fails to achieve 19-21 mpg with a stock 289 or 302. The actuator may be a good place to start looking. Dyno tests consistently show a 5-7 HP increase after headlight vacuum leaks are repaired.
The second area to fail is the internal diaphragm seal. If you use a vacuum tester on your bottom vacuum port and find it does not hold 5 inches of vacuum for prolonged periods of time, then this unit is most likely your problem.
