    Drivers side under the dash up by the HVAC case. The relay is right above that. Whats wrong? No door locks?

    My fuse 13 keeps blowing when I replace it.

    Fuse 13, thats Ford talk. They go by fuse number and not actually what the damn thing does. Well if it blows instantly then I'd say there is a short somewhere on the power feed from fuse to relay. If it blows when you try and use the locks then you can place the short somewhere on the control side of things. FYI, the remote control door lock receiver is nothing more then an input to the door lock relay. You can unplug it and the locks will still work.

    Does not blow instantly. It will take a couple days before it blows. I know fuse 13 controls the door locks, cig lighter, and 2nd row speaker amp. Weird thing is my remote still unlocks and locks the doors.

    Intermittent short to ground. Fun. I don't envy you.

    What does that mean? A frayed wire? What I was going to do was unplug the cig lighter, power door locks, 2nd row amp one by one and see when the fuse stops blowing.

    Thats about the best way to go about it. Like I said all you have to do is unplug the door lock relay and you will isolate the power from the fuse to the relay on that circuit. That is where it stops until an input from a lock switch or remote controlled door lock receiver hits the door lock relay and then the relay switches the power to where it needs to go.

    Re: Power door lock module 97 Suburban

    OK guys I finally got around to looking at this. First, how in the hell do you get behind the cig lighters to unplug them? I am pulling on them but I want to be as easy as I can on my dash as not to break anything.

    Secondly the amp for 2nd row speakers is not under the drivers or passengers seat. Where else could it be, remember I have a 97 Suburban.

    Anyway I put a new fuse in, it will work for a couple of days. I want to find the correct way to unplug the cig lighter because I bet that it what it is.

    Let me know.

    I have a 99 Suburban. I am having some of the same problems as you. My interior locks do not work but my keyless entry does. Fuse 13 (Cig Lighter) blows as soon as I put a fuse in. I have taken the three 12 power supplies and unplugged them and the fuse still blows. I would like some help.

    We took the cig lighter out of the plug and it hasent blown since. We ran the Suburban for 5-6 years with fuse 13 blown, removed the cig lighter the other day and has been fine since.

    Make sure you don't have change in the ashtray falling into the cigarette lighter,that's the most common cause of the cigarette socket shorting out.

    With only 3 things on the circuit,shouldn't be hard to narrow down.
    It's either a short to ground on a wire or a shorted component.
    Try to find a trigger,when it blows the fuse what is happening or what are you doing?
    Are you driving over a bump?Hitting the door unlock switch?Turning on the brights?
    Whether it be a frayed wire or a shorted door lock actuator something will usually trigger the short if it isn't constant.
    I would put in a new fuse and start unplugging circuits till it stops.
    If you have a multimeter then check all circuits for resistance to ground,pay particular attention to wires that aren't ground wires.
    Ground wires should have no more than .5 ohms resistance to ground,the power/signal wires should be OL/outlimits.

    And please don't just leave the fuse out-
    Then when someone wants to read your CEL/SES they have to change the fuse since the DLC is powered by the cigarette lighter.

    The poor idiot at autozone will be in tears trying to figure out why he can't read your codes so he can sell you that 02 sensor.
