My interior lights work, the window drops when opening and closing the door, but both power windows and my convertable top don't wor.
Any ideas what it can be? My fuses are good, I swapped them out and am getting 12 volts, but it doesn't seem like my switches are getting any power. Could it be a relay? Do the power windows feed through the convertible top double relay? Any help would be appreciated.
Automotive (any) electrical wiring/trouble-shooting is not my strong suite.
Whenever a relay is involved the techs have a bypass relay to use to eliminate the relay as the problem. It might be worth the expense of just buying a new relay.
In the meantime, what you can try is do a battery disconnect and long enough to ensure the car has lost all residual electrical power then reconnect the battery.
If required for your car, be sure you have the radio code.
Be sure the ignition is off and the key is removed from the ignition switch.
Follow proper procedures when disconnecting the battery and then connecting the battery.
If the switches still do not respond when they should (the key has to be on IIRC) and power is good then there is a fuse, relay, or other electrical problem. This could include an ignition switch problem though the behavior you describe is not any I have read being associated with a bad ignition switch in the past.
