I have an 01 Sahara as well. You will need to remove the top portion of the dash that runs along the windshield, it has the defroster vent on it. To remove it just slide a flat head screwdriver under it and pop it up along the length of it. After that there are two philips head screw you need to remove that were under the piece you just removed right in the center of the top side of the dash. Once the screws have been removed take your ashtray out and there is one more philips head screw behind it, remove it. Now after all three screws have been removed you can pop the entire center part of the dash off by pulling it away from the dash, once you have it off you have access to the back of the switch panel. It takes no more than 5 minutes to disassemble the dash; I’ve had mine apart at least 6-7 times.
BTW... welcome to the forum!!
