I am not aware of any circuit breakers in the power lock system. There are however, two relays under the right kick panel. The relays are energized by the door mounted switch and they in turn then energize the door lock solenoid. To test, you can apply power to the relays directly to see if it energizes the door lock solenoids or not. If it does, there is a problem with the swtich or the power to the switch or even the wiring in that area. I can only assume that you've checked the fuses. ----- Original Message ----- From: <jvguilbault@xxxxxxxxxxx> To: <mailing-list@xxxxxxxxxxxxxxxx> Sent: Monday, April 05, 2004 6:58 PM Subject: IML: Power Door Locks Hey, guys. My 76 NYB has power door locks that don't work. Nothing at all happens when you push the switch on either door. I read in the owners manual that these have circuit breakers on them, but it doesn't say where the little devils are. The car recently had some electical problems, so it seems likely that the circuit breakers blew. Any idea where I can find them?
