1970 Eldorado Ignition relay location?

[billmorrow]

Hello..
The power windows, all of them, just decided to stop working on my 1970 99k mile eldorado..
the car is all original and a solid 4+
i have jumpered the window switch in the driver door and the windows will then work..
the manual says to next check the ignition relay that supplies power to the windows when the ignition is switched ON
it also suggests that the relay is located left of the steering column behind the left side trim panel..
there is no relay there or any place else that is related to the windows..
i have traced the wires (r/w) from the door wiring harness to the main body harness connector and from there they go under the frong carpet toward the right side of the car..
NO RELAY is anyplace to be found..
if ANYONE has ANY thoughts or ideas as to where this unicorn of a relay might be found, PLEASE please tell me or show me with a picture..
thank you

In the RWD vehicles, the relay is in the kick panel behind the harness connectors.  There is a three-pin connector to the relay with orange/black, red/white, and pink wires.  I suppose the FWD vehicles could be different.

thank you for your reply.. :-)
"kick panel" ? is this the same as the left side trim panel between the emergency/parking brake pedal and the sheet metal where the door harness comes though..?

[klinebau]

yes, this is the same.

thank you..
no relays there or anyplace EXCEPT the horn relay/annoying buzzer just forward of the steering column..
i have pix but do not see a way to attach the same..

There should be a red/white wire coming in from left door that connects to a harness with 6 connectors (3 x 2 with one slot empty).  Follow the red/white wire from that connector to the relay.  I attached the relevant circuit diagram.

hello and thanks for the reply..
i have that same circuit diagram..
i HAVE tried following the red/white.. it runs from the door harness to body harness plug to under the front carpet and disappears someplace toward the passenger side..
today i proved the door harness by disconnecting that plug and jumpering from the battery to the red/white in the door harness.. result, windows work fine..
i am beginning to think there is no ignition relay..
i have searched the area the manual SAYS it is located in and all i can find is the horn relay..
i search parts web sites and there is no mention of an ignition relay..

There is definitely an ignition relay (sometimes it is called a window relay).  For the RWD cars, the ignition relay is located in the left kick panel area mounted to the  the sheet metal behind the three connectors.  The FWD vehicles must be different.  If you see the red/white wire going to passenger side, then I would find where it emerges in the right side kick panel.  I still think that will lead you to the relay.

I just checked the Fisher body manual and it clearly shows the location of the relay for the RWD cars in the body wiring routing diagram.  It does not show the location for the Eldorado, however.  That is strange.

Even though this thread is for a 67 Eldo, it might indicate that the relay is located further up in the cowl.  Take a look at reply #10.

i went looking for that relay again, today, sunday, on the right side where the wiring points and nothing found but dust..
looking at the wiring plan again i see the ign relay wiring might be close to the door open "buttons" so i'll try to follow that monday..
if no joy i will just wire around the relay which will mean that the power windows will work all the time and no i won't wire in a parallel but working relay..
power windows that work all the time are good.. my '59 convertible windows work all the time.. so why not the '70 eldorado..?!

Is it also the Horn Relay?

Because I know where that is in my '72 Eldorado.   It is also the ignition Key Buzzer if that helps.

According to the diagram provided, relay is fed from 3 wires, orange& black, pink and white, and purple.  Diagram didn't go far enough to show origination point.  So those are the ones you need to find and "back" trace to the relay.   
I've mentioned before, the "old" style like the '59, was the window contacts were full amperage and they often failed due to corrosion/sparking, so they went to relays to take the amperage off the open contacts of the switches.

thanks but not the horn relay.. :-(
though i DID wonder why i never saw that horn relay there in front of the brake pedal while tearing hair looking for the ign relay.. i MIGHT just defeat that damn buzzer, though, now knowing where it is hiding..

thanks for the thought.. can't find those colors anyplace outside a thick bundle of wires..
the window buttons on my '59 work just fine though the top up and down button might benefit from a relay.. since i replaced the hydraulic pump and top cylinders the top moves more slowly and might be drawing more amperage.. the new top is so tight i must max out the pressure so as to be able to lock it when UP..
will try to find it one last time by following the wires from the 2, side by side, door open buttons which the wiring diagram tends to indicate MAY be in the same bundle..
