They quit working all of a sudden. Checked fuses all were good. Any suggestions?

 

I mean the power lock / trunk doesnt wrk. Windows work fine.

 

Any one?

 

Are you talking about through your remote or the actual buttons? If its your remote, I have that same problem. I would have to find an installer who knows how to reprogram the alarm. My remote start works. But i messed with the receiver and screwed it up.
If its with the actual Buttons, You may have a bad Relay or 2! That's all I can Figure from what you described!

 

Ok yea its the buttons.

 

If your FOB doesnt work which is the keyless entry, I would think the battery needs to be replaced. Make sure to get the right battery for it and depending on your year you can reprogram the FOB through the headunit on the dash. Just google, "how to reprogram a FOB on a "insert year make model"'
