i have a 1999 jeep grand cherokee power windows and mirrors are nat working checked all fuses and they are good then took a test light and checked wires at switch and am not getting any power anyone have any suggestions on what to check next
Look for a broken or disconnected wire. Or wires.
Make sure you have found all the fuses and relays. Some vehicles have more than 1 fuse/relay block. My Camry has like 4 different places they hide fuses and such.
Righto - check not only the inside fuse box, but also the relay/fuse centers under the hood.
