I would still suspect broken or damaged wires in the wiring harness in either front door hinge area.
THIS IS ONE OF THE MOST COMMON PROBLEMS IN ZJ's
I have had wire damage there maybe 20 times causing speakers, door locks and windows to fail. I have even had dealers make me get new window motors and door lock actuators when the problem eventually came down to a broken, frayed or damaged wire in the door harness.
I am betting the lights dimming is coming from a short in the wires where the wire is touching a body part, sapping the current
Keep checking the wires - pull back the rubber accordion sleeve - it may be further inside the door or frame

Good luck

Don't buy a new actuator. It will cost you nothing but time and a bunch of WD40.

Pull one of the door panels and pull the actuator. Clean it up with Qtips and WD40 inside and out. Work the switches back and forth and clean it some more. When you think it is clean, put it back in and try it out. If it works, be sure to lubricate it before you put the door panel back on.

And, yes, mine quit locking before it quit unlocking. If you can hear the switches trying to work, then the power is actually getting there. Also, there are only two wires going to the actuator. I think that if your doors unlock, the lock function is just a reversing of polarity.

The lock on the drivers door of my '95 XJ is getting worse. The actuator has not been able to unlock it ever since I've owned it unless you use both hands to hit the power button and push on the manual button too. But it's extremely difficult to unlock with the key too. Can the key hole unit be cleaned also?

Spray some wd40 in the key hole. Mine wouldn't even unlock with the key and that freed it up.

Once I do that, is it a bad idea to blow it out with an air hose to keep things from freezing together in the cold weather?

Wd40 doesn't freeze

I'll try it today and report back. Last night it took me 20+ trys to flop the lock all the way open.

Same thing happened to mine last year. Battery ended up dying on my girlfriend. I got out there jumped it and the security system came on and doesn't go off or start until you lock and unlock the drivers door. Needless to say it wouldn't unlock. After about 10 minutes of messing with it in below freezing temps it finally unlocked. Went straight hinge and sprayed all the locks with wd40 and never had a problem again.
