What you mean froze solid, something seems odd with that
Sounds like the ingition was changed and the door locks were not, just because the key goes in doesnt mean it is the correct key. I only mention this because in my 92 I had to change the ingition, but I didnt change the door locks

the relay is the timer

 

That is a good point. Or both of the locking mechanisms are broken. One of my work trucks is like that, the driver door will not unlock with the key, but the passenger door will.

Will the ignition key lock and unlock the tailgate?

 

I asked P.O.,(original owner) he stated locks never changed, never used door lock cyls, hasn't used tailgate lock in 4 years since he took bed cover off.

Locks having been changed was my thought since they are stuck solid. Thought about getting a key cut from code to see if it matches existing key or would will in ign. hate to tear the doors apart if it's just a key mismatch.

 

all three locks on one truck are bad . That's gotta be really rare

 

I have before, but not on a vehicle this nice. I'm leaning toward igntion having been re-keyed but not body locks. Oh-well, something else to expalin to a potential buyer.

 

I have a 2003 F250 with the V10. I have owned it since new. A new problem started 2 days ago. The dome light and truck bed light should go off when you are driving down the road. Mine does not. The illumination inside the cab is so bright that I cannot drive safely at night. Must be the GEM. This may be another case where Duck tape comes to the rescue, covering both the dome light lens and the truck bed lens. This is my third V10, I love them, but NEVER take a V10 that is operating well back to a Ford Dealer on a "RECALL". Ford ruined my 1997 V10 by messing with some board mods.

 

door switch should be part of the door latch
sounds like you have GEM issues open it up and look for signs of corrosion and or moisture.

 

I think a few Xanax are in order. It's just progress. I use key fob and lock the doors, lights go out.

Pull the bulbs and get you a flash light for nite driving.

 

When I bought my used 99 super cab , I had a problem with the dome lights staying on as was mentioned in an above post .
I sprayed all of the latches on all 4 doors with cryoil , and they all work properly now.
