We have recently purchased a 2003 Escalade EXT and it came with a key fob that wouldn't work. We tried replacing the battery, but didn't work. We have since replaced the key fob, but still nothing. We have also tried reprogramming the key fob but nothing. Is it because the driver's side door lock doesnt unlock or lock with the power button. The same panel works for all other doors, just not the driver's side. So we have to lock it by hand before leaving the vehicle while still using the button for the rest of the doors. Then the alarm goes off randomly at night. Back to the door locks, you can hear the actuator working but it doesn't lock or unlock. Any ideas? We would like a fix as soon as possible Thanks in advance! xx

 

Could be in the switch itself, you can get one here Cadillac Escalade Window Switch has a 30 day return policy on it, so if it doesn't solve your issue it can be returned. Have your vin number ready as there are many versions of this window switch. Also make sure to read the description as these switches need to be programmed to make the mirror functions to work.
