Rear doors do not lock

[brianmm22]

So I have a 94 F350 4 door and the rear doors just don't lock. It doesn't work with the power or manual. I have the door panels off and everything seems to be hooked up. Has anybody else had this issue? What was the problem?

its a burnt out/stuck solenoid
need to replace.
just maybe you can get it to free up, but i doubt it.
has had this issue on my 87

If it has the short manual locking/unlock "spire", extra long ones are available at most any parts store. If the solenoid coil is not burnt and holding it, you can work it up and down and try to lube it with PB Blaster or a silicone spray. There a ***** to work on.

Does the lock rod fail to move? Or does it move, but fail to lock the door?
