79' - Electric door locks
Hi,
Both electric door locks on my 79' do not operate (nothing happens or heard). Also, when I use the key to unlock both doors, it takes so much effort and it seems like the key is going to break. What do I need to replace? Actuators? If so, I see prices all over the place.
Thanks in advance.

It was very common for people to disconnect the connector to the door lock switch, especially after having locked the keys in the car.
Solution: remove door panels, check to see if door lock disconnected. If not contacts may need to be cleaned. Test that connector has power.
Regarding using key to unlock doors: there is 41 year old grease in the lock and actuators. Clean them both and re-lube with white lithium grease.
Both items have been discussed in other threads.

Considering you feel like you'll break the key when unlocking your ONLY course of action is to remove, clean and lubricate the entire mechanism! Use white lithium grease on the arm pivot points. You can clean out the big lock mechanism with WD-40 and then lubricate with a machine oil. Use graphite to lubricate the lock cylinder.
The lock actuators will probably be shot. Look for Doorman brand replacements from general suppliers as they are still common parts.
While you're in there I suggest you completely recondition the window mechanism.
With some searching you'll find excellent instructions on how to do this.
