So the wife tries to get in the truck the other day using the code and says its not working, I tell her the code and again it doesn't work. I can get the keypad to light up when I press it but nothing works, the code, 78/90 to lock or anything for that matter.

BTW I added the LT door handles about 6 months ago and had no problems until now, any ideas? Would the dealer warranty the work if needed even if I switched out the factory handles for LT's?

Any Ideas?

 

Mine just started messing up too. That is all I use. It is like my rear window, it works when it wants to. I haven't had time to mess with it now but this weekend I am going to try to see what is up.

 

If it ever stops raining here I will to, let me know if you find anything out while working on yours.

 

Update on keypad not working.
I received a replacement handle from Tasca yesterday and installed, it worked fine for about 5 minutes, I tested the keypad code 3 times, locking and unlocking, along with the 78/90 lock feature, after that it no longer works again

Anyone have any ideas as to why? Domenic @ Tasca said he would look into it as well, just asking you folks who may also have some input.

 

sounds like you have a critter that is chewing through some wires....jk....i have no idea....might have a short in the vsm or something. i believe that controls the keyless.....

 

Just curious, What's this 78/90 lock feature? And does it pertain to the 04's? It's raining cats and dogs right now and don't want to after the manual. I feel for you since I would hate to loose the function of the keypad since I use it all the time.

 

You press the 78 and the 90 buttons at the same time and it locks all the doors.

 

Hi, my 2007 fx4+ did something similiar.....although iirc it never lit up from the start nor worked...found out the hard way by locking my keys in and the keypad was dead. I took it to dealer and they fixed under warranty.

From the service invoice it sez:

i) pulled door panel, found keypad/door wiring ok
ii) removed rear seat back, & access vehicle security module...checked wire, no continuity
iii) followed wires down floor underneath sill plate & into kick panel...remove e-brake assembly to access connector c2095 from drivrs door to cab-interior...found pin #8 circuit #78 pushed out of connector
& mashed into outer wiring of male side.
iv) replace damaged pin in connector, connector otherwise ok.
v) function test system, ok.

...fwiw, maybe a couple other places to look for a loose connector that may be behind your intermittent problem.

 

good call and man your dealer is good for documenting that well........
