HiCustomer welcome to Just Answer!.
Is this a factory alarm system?
Do you have a working remote keyless entry transmitter, kathey?
Let me know if it was working until this started, but isn't now.
Have you tried manually unlocking the passenger side door or the liftgate to disarm the alarm? The driver's door switch gets much more action than the other locks, so it may only be that you need to use a different unlock location until you can get this one fixed.
If neither of these suggestions help, check a few more things for me...
Does the dome lamp come on?
Do you hear a key-in ignition chime?
Do the exterior lights work?
Does your intermittent wipe function work? Steady speed wiping is hard-wired... I'm concerned about the intermittent function.
If it's a 4x4, do you see a "Service 4x4" message in the cluster?
If you have any of these problems (and some others that escape me) in addition to the factory alarm problem, you probably have a locked up central timer module (CTM), the module that controls practically all vehicle lighting as well as theft and wipers.
The CTM is located in the left kick panel, just behind the park brake pedal. You have to lift the door sill plate off first, then pull the panel straight toward you to disengage (no screws). The CTM is the black plastic box, roughly 6"x6" and has three electrical connectors.
Disconnect all three and wait about a minute before reconnecting. If functions that were previously inoperative come back to life, you'll be needing a new CTM at your first opportunity.
Write back if you have any questions or problems. I'll be glad to help.
